cable

China wants to lay a cable from Chile to Hong Kong. And in the process, it has put Chile in a storm against the US

by

Next March 11, Chile will have a new president. Gabriel Boric will no longer be in charge of the country and José Antonio Kast will land in the presidential chair. And he arrives just to take care of a morrocotudo mess: the submarine cable that China is deploying from Valparaíso to Hong Kong. And, evidently, the United States does not like this situation one bit. To the point that he considers it dangerous for his safety. In short. On February 20, the United States revoked the visas of three Chilean officials. The reason? Concern about an underwater cable that will connect Chile and Hong Kong. It’s not so much the cable, but who is ‘pulling’ it: China. As they point out in Mercopressit was the outgoing president who managed the agreement to deploy this cable through a concession decree signed on January 27, which allowed the company China Mobile to install, operate and exploit the cable. 48 hours later, that act was annulled citing “technical errors” and the Boric Administration commented that the project was in the evaluation process. The United States, however, wasted no time and banned the visas of the Minister of Transportation and Telecommunications, the Undersecretary of Telecommunications, and the Chief of Staff of Subtel (Chile’s Undersecretary of Telecommunications). The storm it had just started. political war. Marco Rubio is the Secretary of State of the United States and accused Chilean officials for having “knowingly directed, authorized, financed and supported activities that compromise critical telecommunications infrastructure.” You may be wondering what the United States cares about what Chile does, but Rubio continued by pointing out that this decision “undermines regional security in our hemisphere.” “Which hemisphere” is not the question, but what is happening now. Because Chile has responded that the accusation is “absolutely false” and describes the United States measure as “unilateral,” also pointing out that it is something that goes against Chile’s sovereignty. China has not stood by and, through its embassy in Santiago de Chile, accused the United States of acting in a hegemonic manner, ignoring Chile’s sovereignty to carry out these projects in its territory. If you look closely, the cables from the American continent pass through the US except for Google’s Halaihai, at least directly Cross-fire. Brandon Judd is the US ambassador to Chile and has sided with his government… going a little further in the accusations. Affirms which had already warned the Chilean authorities of what would happen, describing the agreement with China as an intrusion into Chilean telecommunications systems carried out by “malicious foreign actors.” And, as we said, it will be next March 11 when the new president will take office with a pending task: solving a monumental ballot. From the Foreign Relations Department of the incoming president, it has already been saying that “everything possible will be done to ensure that foreign policy allows for the best possible relations with all countries.” A 0º, neither cold nor hot. Influence. Leaving domestic and foreign politics aside, the cable is known as Chile-China Express and is estimated to measure almost 20,000 kilometers. It will link the Chilean city of Concón and reach Hong Kong. The budget is about 500 million dollars and its importance seems key because it would represent the first transpacific data route that would completely avoid routing through North America. From China Mobile it is pointed out that this cable will allow establish Chile as “the central node of the computing power network between China and Latin America.” Now we begin to understand what it is that “undermines regional security in our hemisphere” to which Marco Rubio referred. If completed, it will be a cable deployed by China and in which the United States will have no say, but which reaches the American continent. And we say that it is an important ballot for the new president because the United States injects a lot of money into Chile, being its main foreign investor, but China is the main trading partner of the country. A cable is going to put Kast between a rock and a hard place. Not only in telecommunications. In the background, we have a United States that is looking at the wolf’s ears. In recent months, and at an accelerated pace, China has been moving its chips. It has done this in developing countries on the African continent through energy deals, infrastructure construction, agreements to mine strategic elements and expand its automobile market. But he is also doing it in America. When the United States turned its back on Mexico with tariffs, China was there to offer to open factories. He is carrying out energy projects on American soil, he has interest in some of the strategic ports of the continent and is rolling out infrastructure, such as a railway line that, if completed, will link South America from east to west. The cable between Hong Kong and Chile is just one more piece of a puzzle that Beijing is weaving, which has already torn off with the works. And Washington only sees one thing: the wolf at the doors.

The first great Atlantic submarine cable that connected us to the internet says goodbye for a simple reason: it was too expensive to repair it

by

It has been at the bottom of the sea for more than two decades, forgotten. But now, finally, the TAT-8, the first fiber optic cable that crossed the Atlantic and connected us to the Internet, is being removed from its place. And to understand the importance of this, it is worth telling its story, since perhaps the Internet would not be as we know it without this cable. The cable that started it all. On December 14, 1988, AT&T, British Telecom and France Telecom developed TAT-8, the acronym for Trans-Atlantic Telephone 8. It was the eighth transoceanic cable system between Europe and the United States, but the first to use optical fiber. Before him, transatlantic cables ran on copper, with very limited capacity. With the TAT-8, voices and data traveled converted into pulses of light through glass threads thinner than a hair. Just like account Wired in its report, at the inaugural event, writer Isaac Asimov connected by video call from New York with audiences in Paris and London to celebrate, in his own words, “this inaugural voyage across the sea on a ray of light.” Why was it so important? When it came into operation, the Internet was still too technical a concept for the general public. But the TAT-8 literally built the highway on which everything later circulated. The curious thing is that in just 18 months it already reached its maximum capacity, so this forced new cables to be laid as soon as possible, especially after the outbreak of the world Wide Webelectronic commerce and in a context in which the Internet became increasingly relevant. By 2001 the TAT series had already reached 14. Disconnection. Just like account In the middle, in 2002, the TAT-8 suffered a breakdown, and repairing it was not worth it, it was that simple. With more modern and higher capacity cables already operational, it made no sense to invest in their recovery. It went offline and was abandoned at the bottom of the Atlantic, where it has remained for more than two decades. Now they are taking it out of the sea. According to collect Wired, a specialist company called Subsea Environmental Services is physically recovering the cable with its vessel MV Maasvliet. It is one of the few companies in the world whose entire business consists of recovering and recycling retired submarine cables. The operation involves dragging a flat hook across the seabed, waiting hours until tension is felt in the cable, and then hoisting it aboard meter by meter. The workers they explain As the ocean floor is an increasingly crowded space, and recovering old cables frees up routes for new ones. What is done with the remains. The TAT-8 is not thrown away. Fiber optic cables contain high purity copper, steel and polyethylene, all recyclable materials with market value. Copper, especially, is a valuable resource and may become scarce in a few years. And according to the International Energy Agency, in less than a decade could be scarce if the industry does not find new sources. On the other hand, the steel of the cable will end up being converted into fences, and the plastic, processed in the Netherlands, will be transformed into pellets to manufacture non-food packaging. In fact, just as they count At Wired, you may soon be using shampoo in a bottle made from remains of the first fiber optic cable to cross the Atlantic. Sharks. Curiously, the TAT-8 is at the epicenter of one of the legends that has lasted the longest in this sector: that sharks bite internet cables. Just like share In the middle, it all started with a test prior to the TAT-8, the Optican-1, which ended up failing due to problems in its insulation. A Bell Labs engineer appeared at a conference with shark teeth that had supposedly been removed from the damaged cable. The story spread instantly. As well as point At the time, AT&T even included four pages on protection against shark bites in its press kit for TAT-8. Actually, there has never been consensus about whether the sharks really caused that damage. Subsequent tests in aquariums, where they were starved to see if they would bite into wires with electric fields, did not yield any clear patterns. At least the outcome of all that testing and debate was positive, as engineers added a layer of steel between the insulation and the fibers, which improved the cable’s overall resistance to abrasions and damage of all kinds.

when you need to buy the most expensive cable and when the 5 euro one is worth it

by

You go to a store like Amazon and type ‘HDMI cable’ in the search engine. The results show a lot of options and all, at a glance, they are almost identicalyes. Yes, there are braided cables, cables of different lengths, or you can even find cables of other colors, but there doesn’t seem to be much difference between them all. Despite this, there are very cheap cables and others that cost more than 20 euros. Your first impulse may be to go for the cheapest one that has the meters you need. Ideally, you should spend a moment on the details, since the cheapest ones are usually HDMI 2.0, while the most expensive ones are HDMI 2.1. What does that mean for you? Let’s take a look at it so you know if it’s worth investing a little more or if one of these cheap cables works for you. Choosing an HDMI 2.1 cable In short, HDMI 2.1 cable is better. The main difference between this and HDMI 2.0 is that it has greater bandwidth (more than double, in fact). In practice, this means that the cable can handle and transport more information per second. Since we are talking about an HDMI cable, we are referring to image and sound. Precisely because it has more bandwidth, this cable can move higher resolution at higher hertz. It is the right one if you plan to see 8K resolution content (although for commercial 8K content there is still) or if you are looking to play something at 4K at 120 Hz. The latter is what leads many people to go for one of these cables because it is the way to get the most out of a PlayStation 5 or one Xbox Series X. To the greater bandwidth of this cable, we must add some technologies such as dynamic HDR or others that are also great for video games and that are not present in HDMI 2.0. The most important one is called VRR (either Variable Refresh Rate), which basically makes the console or PC and the TV “agree” so that the image does not jerk. We have two examples of VRR with two technologies that are usually present in many monitors, such as NVIDIA G-Sync or AMD FreeSync. There is also ALLM, which makes the TV’s Game Mode activate automatically when you connect the console. This is very convenient because it will save you from doing it manually every time, but it is great when playing because reduce latency. That is, it minimizes the time that passes between you pressing a button and the action being displayed on the screen. For competitive games it is key. If you have a good sound bar for TV at home and you want to connect it via HDMI, then choosing an HDMI 2.1 cable may be a good idea. Here comes into play what is called eARCwhich allows you to command uncompressed audio in the highest quality from the TV. Where is the “but”? So that all these things that we tell you are worth something, It is necessary that both the TV and the console or PC are compatible. You can use the cable if they are not, but you will have spent more money and you will not be taking advantage of it. The good thing is that check if your TV or monitor has HDMI 2.1 It’s not difficult. Choose an HDMI 2.0 cable The best cable doesn’t have to be what you need. The HDMI 2.0 cable has less bandwidth, as we said above, but it is still more than enough for 4K and 60 Hz content. This combination, today, is the most common when playing with all consoles. Plus, it still supports HDR. For this reason, it can be great for consoles from previous generations (PlayStation 4 or Nintendo Switch, for example) or for a TV Box. Another asset that this HDMI 2.0 cable has: the price. Generally, this type of cable It is significantly cheaper than HDMI 2.1. That, which is great for our pocket, also allows us to buy one of better quality without having to spend a good pinch. Because yes, the quality of the cable or connector matters (a lot). And the distance, because the longer the cable is, the more likely it is to suffer losses or interference. What is the main drawback of this cable? May it become obsolete soon. If you don’t plan to change your TV or console right now, HDMI 2.0 is perfect. Now, when you switch to a newer device that supports HDMI 2.1, you will have to buy a new cable if you want higher resolution and more fps. In other words: if renewing consoles or TVs in the short or medium term is on your mind, buy an HDMI 2.1 directly. The good and the bad of both options, face to face HDMI 2.1 HDMI 2.0 THE GOOD 🟢 It reaches up to 8K and 60 Hz (or 4K and 120 Hz) and has exclusive technologies It’s cheaper and still capable with 4K and 60 Hz THE BAD 🔴 It is more expensive and you will not get the most out of it if your TV is not compatible It will soon become obsolete if you plan to renew your TV or console. Ideal for: Play at higher fps and higher resolution with a PS5 or Xbox Series X and to play audio in the best quality Consoles from past generations or watch movies, series and football if you don’t have an 8K TV We do the math to see which one can compensate you more. Both options have their advantages and disadvantages, so now let’s see which one may interest you more depending on which cases. Here it will depend a little on what you are looking for, but especially on What TV or monitor are you going to use the cable for?. The advantages in resolution, Hz and technologies of HDMI 2.1 are obvious, … Read more

the new life of your Cable Car

by

This week, January 20, 2026, works started to dismantle one of the symbols of Madrid. They are, however, the first step to modernize it and adapt it to current security standards. With more than 50 years Behind them, the Madrid Cable Car is being taken down. The reason is a comprehensive renovation of the infrastructure. In fact, the cable car will remain alive but The iconic image will no longer return of the blue cabins supported by cables that seemed to flex too much. Because those cables with more than half a century behind them are being dismantled. The project includes a completely renovated cable car. Fewer cabins, faster journeys and, of course, the obligatory announcement that we will have the AI ​​monitoring possible incidents. It is a turning point in a story that was born at the end of the 60s. A cable car to nowhere Year 1969. Gento continued running on the Real Madrid wing and Gregorio “Hacha braba” Benito brought order to the center of the defense. But the team’s best years in Europe had passed. Gárate, Ufarte, Adelardo and Luis Aragonés would lead Atlético de Madrid to become League champion the following year and a few years later to brush with glory in Heysel before that great shot hit the net by one of those Germans with an unpronounceable name. The 60s gave way to a new decade and Madrid began to breathe a certain air of change without yet letting go of its most traditional signs of identity. Carlos Arias Navarro, then mayor of the city, turned the city upside down to get anywhere by car. Urban highways such as scalextric from Atocha and the proliferation of parking lots honored the rich Madrid tradition of drilling holes in the ground and always keep some work active. But, unlike motorized vehicles, in 1969 Madrid inaugurated a mass of iron that allowed people to fly above what would later become the M-30 and unite the Argüelles neighborhood with the Casa de Campo, then open to traffic and the classic setting for Sunday picnics. The plan seemed perfect to spend a day with the family eating tortillas away from the hustle and bustle. A completely isolated hill that, really, has no services at hand. What then led to building a cable car to nowhere in a city that was in full ferment and whose neighbors seemed eager for new plans? They count in elDiario.es that, really, the current Casa de Campo station was nothing more than an intermediate stop to get to the Amusement Park and the Zoo. That 1969, in fact, an attempt was made to inaugurate the first of these attractions together with the Cable Car, taking advantage of the festival of San Isidro, patron saint of the city, but the flying cabins had to wait because some neighbors tried to stop the project, claiming that the passage of these vehicles did not respect their privacy since they could see the interior of their houses. The Casa de Campo Cable Car station is linked to the Lake, the Amusement Park and the Zoo by roads that run through the interior of the urban park. But then you had to walk through pine trees to get to the recent Amusement Park, which is located just over a kilometer from the end of the cable car. To get to the Zoo it is necessary to double the distance. And the project contemplated joining both spaces with the cable car in a monorail that never came to fruition. If it had left, one of the city’s wealthy neighborhoods would be linked by air to two of the municipality’s great leisure attractions at that turn of the decade. The project, however, was stopped. Since 1969 it has been in operation with the same infrastructure, its cables have remained active for more than 50 years and it is estimated that it has transported more than eight million people. In 2022, a review temporarily paralyzed the facility when it was considered that it was not completely safe and in 2023 it was temporarily closed indefinitely. Now, the Madrid Cable Car seeks to write a new page in its history. This week the works for its dismantling began but a renovation project is already underway, so that the cabins can fly again for almost three kilometers above the Parque del Oeste and the Casa de Campo. They will do it with new cabins and renewed cables from Switzerland. With artificial intelligenceof course, which according to the Madrid City Council will help control incidents. Spaces that will weigh a ton with seats to transport a total of 10 people per trip. The challenge, they say from the City Council, has been to put new material in a space that was designed 60 years ago, they collect in The World. If everything goes ahead as planned, the flying cabins will return to the Madrid sky next year. They will do so after a five-year hiatus and almost 60 years after the first travelers covered that walk that, one day, should have linked the Argüelles neighborhood with the Madrid Zoo.

There is an invisible chip in every USB-C cable that decides whether your phone charges fast or slow: almost no one knows it exists

by

There is a small and notable chip in our USB-C cables. This is the so-called “e-Marker”, which is especially important. The reason is simple: when we connect a cable to a device, it is responsible for indicating to those devices whether the cable supports more or less transmission or charging speed, for example. USB-C chaos is a little less chaos. USB-C connectors completely dominate the market, especially after European regulations that require them to be used to charge mobile phones and other devices. Although they have become the Swiss army knife for connecting all types of devices and peripherals, it is not easy to know what we can do with a cable when we connect it to our mobile phone or laptop, for example. And that’s where the e-Marker chip (Electronically Marked ID chip) comes in, a fundamental yet invisible component of the connectivity of our devices. In Xataka We criticize the EU a lot with its obsession with regulating Big Tech. There are at least two examples that justify this obsession A chip to identify everything. The official specification of the USB-C standard clearly indicates the mission of this chip, which is responsible for showing what capabilities the cable in question has. The document that talks about this chip is the one dedicated to USB Power Delivery, the power delivery function through these cables. Specifically, the identification data includes: Manufacturer and model of the cable. Signaling protocol: that indicates the maximum transmission speedthat is, if it is a cable with USB 2.0 support, or USB 3.2 of one generation or another (Gen 1, Gen 2, etc.). Active construction (in long cables there may be chips that regenerate data signal to act as a kind of repeater) or passive construction (they do not alter the data signal). How much power does the VCONN pin (intended to power accessories) consume? Whether the cable can support 3A (standard) or 5A (required for powers from 100 W to 240 W). Latency (signal delay over the cable). RX/TX directionality (how the high-speed cable pairs are configured). SOP Controller Mode: Whether the cable controller can communicate independently with the charger or device Hardware/firmware version. One of the sections of the USB Power Delivery specification that talks about this chip. Source: USB.org An active safety mechanism. The e-Marker is not only official, but is a mandatory part of the USB Power Delivery (USB-PD) specification dictated by the USB Implementers Forum (USB-IF). This chip acts as an active safety mechanism, and during the power negotiation phase, the chip tells the charger “I am a cable certified to support up to 100W” (for example). If the charger does not receive that digital confirmation, it will assume that the cable is basic and cheap, restricting the flow of power or data transmission. Does your phone charge slowly or is the transfer using pedals? In fact, if a USB-C cable does not have an e-Marker chip, most device drivers will automatically treat it as a USB 2.0 cable. That means that even if the cable is physically capable of more, the speed will be limited to 480 Mbps maximum, and charging will also be slower. With 3A you can reach 60 W at 20 V, so even so this section is not so affected and it also depends on the charging capacity of the charger. {“videoId”:”x8dmqaj”,”autoplay”:false,”title”:”One USB-C TO RULE THEM ALL- the European Union approves a single charger for mobile phones”, “tag”:”webedia-prod”, “duration”:”54″} The rails. High-speed cables (USB 3.2, USB4, Thunderbolt) have multiple pairs of copper wires designed to transmit data in parallel. The e-Marker tells the device “I have all the threads necessary to activate dual lane mode.” If this confirmation does not arrive, the transfer speed is again limited. The e-Marker on long cables. Another function of the e-Marker, as we said, is to identify the length of the cable. At high transmission speeds the signal degrades very quickly, and the e-Marker is responsible for notifying you, allowing the device (mobile phone, computer) to adjust the signal strength to compensate for potential data loss. Support for alternative video modes. Another option that this chip enables is to indicate what video connection standards the USB-C cable in question supports, and if, for example, it has the necessary bandwidth for 4K or 8K resolutions. There are “readers” of the information provided by the e-Marker chip, although they are not cheap: this one from ChargerLAB costs about 140 euros. Two key pins. The “brains” of a USB-C connector are located on two specific pins known as the configuration channel (CC). These pins (CC1 and CC2) allow, for example, the orientation or reversibility to be detected. Since the connector is reversible, the device needs to know which side you inserted the cable to activate the appropriate data pins (TX/RX). When connecting it, the side will be identified, and based on that the rest of the pins are switched for transmission. The other pin of the configuration channel becomes Vconn to power the e-Marker chip. In Xataka | Mobile phone manufacturers first stopped including the charger with every purchase.

ride a 15 kilometer long cable car

by

Mexico City is one of the most massive cities on the planet. Also hell when it comes to transportation. It is about one of the most congested cities in the world because you have to take the car for absolutely everything, but the Government found a solution: the cable car. What we have associated with ski resorts and tourism is in Mexico the artery for thousands of people to move much more quickly and economically. After a line of almost 12 kilometers, Mexico City is preparing something worthy of China. A new 15 kilometer cable car that will become the longest in the world. In short. If someone controls cable cars, that is Doppelmayr. This Austrian company is the largest manufacturer of cable cars in the world and is the one that, as we read in EFEis going to be in charge of the new longest cable car in the world. In total, 15.2 kilometers in length for Line 5 of the Cablebus of the Mexican capital. This line will have twelve stations, will interconnect the suburbs of Álvaro Obdal, Contreón and Beni Contreón and it is estimated that it will be able to transport 3,000 passengers per hour and direction in the 642 cabins it will have. The project will have a cost of about 400 million euros and something that draws attention is the start-up: 2028. It is one of the advantages of this transportation system. While railway lines, subways or roads require years of planning and construction, laying cable car cables is faster and easier. The longest, but not the only one. Those 15.2 kilometers are impressive, but they are not that far from other lines that already operate in Mexico City. Without going any further, Doppelmayr has laid more than 25 kilometers of cable between three lines that operate in different parts of the city and they are already building a Line 4 of 11.4 kilometers in length. In addition to Cablebús, there is Mexicanable (that came before), with another 13 kilometers deployed. Mexicable is the system of the State of Mexico operated by a Mexican company, while Cablebús is from CDMX and operated by Doppelmayr. Advantages. Aside from the short development times from when the project is approved to when it starts operating, the cable car is a relief for daily traffic. The first thing is that it is a simple way to connect the suburbs with the most central parts. Areas that are poorly connected today will be able to access a continuous route with other areas. In areas where the orography is complex and the roads are collapsed, it is a real transportation alternative. And, although it does not have the capacity of the metro, it is affordable transportation and, as we say, any help when it comes to decongesting the city is welcome in a city where Mexicans spend, on average, a hundred hours in traffic jams. There is also a reduction in CO₂ emissions into the atmosphere. The intangibles of ‘Cablebús’. Although they are not perfect and are sensitive to extreme weather conditions, such as strong winds or storms, there is something less visible, but equally important: the state of mind with which the user arrives at their destination. One of the problems that CDMX faces is that the population is geographically far away and disconnected. Travel times from peripheral areas to employment, education or health centers can be up to an hour and a half when the cable car would take about 45 minutes. This reduces the inequality gap, which is measured not so much in money as in hours and opportunities lost by living so far away. A study of the United Nations Office for Project Services measured the benefits of two Cablebús lines, specifically what they called: generalized travel costs. They are everything that a passenger absorbs beyond the price of the ticket, and the conclusion is that traveling by cable car saves 466 million hours in 20 years, 102,000 tons of CO₂ into the atmosphere and users arrive more rested where they need to go. Also safer as they are not exposed to traffic accidents. And, in the end, although they are not a magic solution, in certain cities, especially where the terrain is not a help, cable cars seem like a support for decongest the brutal daily traffic. When lines 4 and 5 are completed (by 2028), Mexico will have about 50 kilometers of public cable car.

The color of your Ethernet cable is not for decoration: it is a key visual language

by

We all have Ethernet cables at home and they are probably different colors. In my case, I have several yellows, but there are also red, blue, green… What many people do not know (myself included) is that colors are not a whim of the manufacturers, but rather They answer a practical question. A question of organization Contrary to what we might expect, the exterior color of an Ethernet cable will not tell us anything about its performance. If what you want is know the category of the cable (that is, the speed it supports), they all come with this detail printed on the cable itself. The color does not tell us if the cable is more or less fast, it is for something totally different: being able to distinguish and organize them better. In Xataka How to convert the antenna sockets in your house into an Ethernet network to bring Internet from one room to another. In a home it doesn’t make as much sense, but imagine a server or data center where Ethernet cables number in the hundreds or even thousands; If all the cables were the same color it would be crazy to identify them. Colors help manage large networks. Ethernet cable colors Although there are some guidelines on cable colors from organizations such as the IEEEand ANSIthere really is no universal color code for Ethernet cables. The meaning of each color can vary depending on the country, the sector and even the company. However, there are many similarities and widely used color patterns. These are the most common uses: Grey/white/black: These are the colors that we usually find for general home and office use. We see them in most routers. Blue: They are the most used cable for general network connections, servers or workstations. Yellow: They are usually PoE (Power over Ethernet) cables, that is, they provide power as well as connectivity. They can be used in IP cameras and VoIP phones. Green: to directly connect two devices such as computers, without an intermediate device. Red: They are usually reserved for critical connections such as security or emergency systems. orange and purple: They are less common colors. According to Cables and Kitsare used to connect systems that require a specific connection not compatible with the usual standards, for example to connect older systems that do not use Ethernet with newer ones that do. {“videoId”:”x8coltz”,”autoplay”:false,”title”:”ALL ABOUT ETHERNET CABLES_ TYPES, CHARACTERISTICS AND WHICH TO CHOOSE”, “tag”:”webedia-prod”, “duration”:”211″} As we said, the color of the cable does not determine its performance, but rather has a practical purpose for those who manage very large networks. With colors, maintenance time is shortened and serious failures such as the disconnection of critical systems are avoided. At home it can also be useful if you have several devices connected to your router and you want to clearly see which is which.

Mobile phone manufacturers first stopped including the charger with every purchase. Your next threat is clear: the USB cable

by

There was a (wonderful) time when when you bought an iPhone, Apple not only included the cable and charger, but also included EarPods headphones. In 2020 the iPhone 12 arrived and They broke that tradition: that box It included the phone and the charging cable, but nothing else. All manufacturers released following that trail with the same speech from Apple: at that point, users they used to tell with their own headphones and some charger, so what they were doing was protect the environment although that argument was not particularly convincing. Of course, they did something else: first They saved money by not including those elementsand then they earned it when you bought them official headphones and adapters if you ended up needing them. Of course one could resort to third-party accessories, although Lumafield CT scans have been demonstrating for some time that cables, chargers and headphones from companies like Apple are expensive because they are small works of art of engineering. In fact, those same images reveal that the same you shouldn’t trust of “strange” cables, lest they be tools to hack your computers. The truth is that Apple’s decision – which other companies such as Fairphone had previously made – made a deep impact on the industryand nowadays it is very rare to find a mobile phone whose box includes a charger, much less headphones. But the thing is can go further. USB charging cables may also be about to disappear from those boxes. Do we really need the USB cable to be included with our devices? A Reddit user revealed recently how when buying his Sony Xperia 10 VII he had found a surprise: in the box There was no charger, but there was no charging cable either.. In the photo included in the post it was clearly seen how this absence was made evident on the back of the box. The Sony Xperia 10 VII does not include a charger or charging cable. It is true that Sony is no longer a major player in the field of mobility, but these types of decisions are what can begin to establish an important precedent that other manufacturers end up adopting as well. At Xataka we have contacted those responsible for Sony to try to find out the reasons behind that decision. In the absence of confirmation, it seems clear that the environmental protection and the reduction of electronic waste may once again be the clear argument, although obviously the savings for Sony may also be relevant. The European Union precisely wanted mitigate the problem of electronic waste years ago. He did it at set the USB-C connector as the standard connector to charge mobile devices, something that for example forced Apple to ditch your Lightning connector. In these years it seems clear that users We have ended up accumulating a good number of USB-C cables to charge our devices. It is something similar to what happened with chargers: a priori we all have one at home, so the need to include them in the box, as is now the case with cables, is debatable. Of course, it also happens that over time mobile phones tend to allow charging at higher power or transferring data at higher speeds, and this makes it necessary to use chargers and cables specially prepared to take advantage of these options. But even in those cases, including the charger or cable doesn’t seem to make much sense. Especially because Those accessories that manufacturers include are the “basic” models that allow you to upload or transfer data, but not at maximum speed. The usual thing here for years is that manufacturers offer that option on the mobile, but we have to buy the specific charger and cable separately, which imposes an extra cost. Will we therefore see fewer and fewer USB cables included in mobile phone boxes? It seems quite possible. Now all that’s left is for the manufacturers of those USB-C cables to solve their big problem: label them well so that we know which one to use at all times.

The first cable that connects it to the peninsula is already in the sea

by

Giulio Verne, a cable vessel from the company Prysmian, crossed the Strait on September 15 to dock in Ceuta. In his winery he brought more than copper and steel: the first underwater cable that connects to the autonomous city with the peninsular electrical system. With this, Ceuta leaves decades of energy isolation behind. And Spain, when looking in that mirror, is reflected the challenges that still Drag in your own networks. Weaving networks. According to the Red Eléctrica press release from Spainon August 26, the line began from the Line of La Concepción, in Cádiz. The cable toured 58 kilometers under the sea until reaching the Ceutí coast, with maneuvers almost 900 meters deep and special measures to protect the biodiversity of the Strait. The boat chosen for this operation, Giulio Verne, is one of the few of the world prepared for this type of missions: it can load up to 7,000 tons of cable and place it more than 1,600 meters underwater. Leaving behind the “energy island.” Until now, Ceuta’s electrical demand was covered with diesel and gas turbines. The result were high costs for the system, dependence on fossil fuels and polluting emissions in an especially sensitive enclave such as narrow. Thanks to the interconnection, Ceuta will stop depending completely on fossil fuels. As we point out in Xatakaup to 87% of the electrical demand can be covered with clean energy. That will be a respite for the environment – about 300,000 tons of co₂ will be avoided – and also for the system invoice, with a saving of about 30 million euros per year. From Ree summarize it with a clear image: This “umbilical cord” will give Ceuta a supply as stable and safe as that of the Peninsula, but also cheaper and sustainable. The challenge is even greater. Yes, Ceuta has ceased to be an “energy island”, but Spain continues to be in more than one sense. The Iberian Peninsula maintains an interconnection level With France of just 2.8%far from 15% marked by the European Union by 2030. In addition, they are still waiting for reach concrete plans To create electric interconnection runners, while they continue to suffer an electric “bottleneck. However, the problem is also internal. Within Spain, at noon there is cheap renewable spare in rural Spain, but at the afternoon, electricity is fallen in urban areas. According to the employer Aelēc83.4% of distribution knots are already saturated, which blocks the connection of new industrial or digital consumption and forces to waste up to 30% of clean energy at some points. Rather than directly relieve these knots – Ceuta’s link responds to another logic – the project demonstrates that Spain has the technical capacity to undertake large interconnections, just what you need to reinforce its internal network and stop losing clean energy along the way. More networks. In Ceuta, the road map is clear and will benefit the electrical system. The second submarine circuit will tend along autumn. On land, the new virgin substation of Africa (132 kV) should be ready in September, and in October the new Algeciras transformation park will be put into service, connected to the existing 220 kV substation. With the Soterrado terrestrial sections almost finished, the official forecast is that all the infrastructure is running before the end of this year. You have to get muscle. The Ceuta cable shows that Spain has technical muscle to undertake complex and sustainable projects, with underground, directed drilling and compact substations. But it also launches a warning: it is not enough to celebrate a new link. The energy transition requires more internal network, more distribution capacity in demand poles, more storage and more international interconnections. Other countries have already advanced. The United Kingdom and Denmark Viking Link premiered in 2023a 765 kilometers cable that crosses the North Sea to import or export electricity according to the wind. Spain, which beats cheap renewable generation records at noon, needs something similar not to run out at night. The Strait already has its “umbilical cord.” The question is whether Spain will know how to weave the network that connects it, really, with itself and with Europe.
