Japan destroys the data transmission record again with 1.02 petabits per second. The impressive has been the distance

Japan has established A new record World Cup in data transmission per fiber optic, sending information to 1.02 Petabits per second through 1,808 kilometers away. The achievement, achieved by a joint team of Electric Industries Summit and the National Institute of Information and Communication Technologies (NICT) From Japan, it marks a new milestone in long -distance optical communications. And best of all: it has been achieved with fiber optics compatible with any device. The key technological jump. The advance does not reside solely in speed, but in the distance traveled maintaining a standard cable diameter. The previous records in speed Pure had reached 1.7 Petabits per second, but only covered 63.7 kilometers. This new brand multiplies by 28 the distance without increasing the thickness of the cable, bringing technology to real commercial applications. Image: Ispreview How it works. The system uses an optical fiber of 19 nuclei integrated in a cable with standard coating diameter of 0.125 millimeters, the same as the current fibers. Instead of a single beam of light, the fiber transports 19 parallel signals taking advantage of both the C and L bands of the optical spectrum. Electric Sumitomo optimized the structure and disposition of the nuclei to minimize losses, while NICT developed amplifiers capable of simultaneously enhancing the signals of all nuclei. Dimension of achievement. To contextualize the magnitude: 1 Petabit is equivalent to 1,000 terabits or 1 million gigabits per second. Compared to The average broadband speed in Spain (which is usually around 250 Mbps), this record is approximately 4 million times faster. At this theoretically, 10 million 8K video channels could be transmitted simultaneously. Or download the entire Netflix library in seconds. Practical implications. The record establishes a new standard within the framework of “capacity-duty” (1.86 exabits per second-kilometer) using standard diameter fiber. This means that future networks could exponentially multiply their ability without changing the existing physical infrastructure. Intercontinental submarine cableslike those that connect Europe with America, they could benefit from this technology, although at greater distances (more than 5,000 kilometers) the speeds would be lower but still impressive. The way to commercialization. Although these advances will not immediately reach domestic connections, they do mark the future of long -distance communications. The team now works on improving the efficiency of amplifiers and signal processing to bring technology closer to its real implementation. Global Internet traffic grows, but it’s nice to know that the optical fiber and the form of the cables we use today, they are still enough to evolve in this field.

Many Spanish music festivals are financed by an Israeli fund. And some are already distance

After the recent one Eurovision Festivalthe presence of Israeli capital in events around the world begins to be discussed by activists and even by certain governments, as in Spain. Israel has become a uncomfortable presence For certain cultural events and many music festivals, such as Sónar, they are checking it in recent weeks. Sónar takes a step. He Sonar Electronic Music Festival He has distanced himself from the KKR Investment Fund, current owner of the festival through an intermediary company, in a movement that culminates a few days scrambled in the Spanish scene of large festivals. Public opinion and many groups have been contrary to the interference of the company, with pro-Israeli interests, at several festivals. Sónar has expressed With a statement its “solidarity with the Palestinian civilian population trapped in the humanitarian catastrophe that is lived in Gaza.” It is the second one that broadcasts in a few days, after one that He was criticized for his excessive warmth. This statement is a simple declaration of intentions, since Sónar will continue to be the property of KKR. What is KKR? An American investment fund whose acronym corresponds to Kohlberg, Kravis and Roberts, surnames of its founders, and which has established itself as one of the world’s largest private capital companies, with assets of more than 400,000 million dollars. Among the most criticized kkr activities There are real estate investments in Palestinian territories occupied by Israel, such as Jerusalem Este, Gaza and the West Bank. KKR also controls Guesty, an Israeli platform for real estate property management, which reinforces his presence in the country’s housing sector. KKR has also invested in Israeli technology and cybersecurity companies, As Optivwhich was founded by former intelligence ex officers of the Army of Israel. Finally, Henry Kravis, KKR co -founder, is an acquaintance donor of cultural and political initiatives promoted by Israel and has financially supported US politicians aligned with Israeli interests. Within your team there are Figures like David Petraeusformer director of the CIA and president of the group in the Middle East, which makes clear their interests in the region. Festival intervention. A week ago, the newspaper El Salto He published an article About how KKR had acquired in 2024 Supersruct Entertainment for 1.3 billion euros. It is a company that organizes some eighty festivals worldwide and that in Spain is behind events as known as Sónar, Arenal Sound, or are Do Camiño, Love The 90s, Resurrection, Viña Rock, FIB, Monegros, Brava Madrid, Tsunami Xixón or Granada Sound, among many others until they add about twenty of them. At the moment, Sónar is the only one that has been unmarked from the policy of the investment firm, ensuring that he had no “control” on the company’s investments or decisions. Groups that protest. Although the festivals have not been unmarked from the presence of KKR, many groups have done so, especially those linked to social causes. Some of them They are repeat offenders, Fermín Muguruza, Non Servium, the last Ke Zierre, Sinkope, Kaos Urbano or Porretas. And the Spanish case is not unique: the London platform Boiler Roomwhich broadcasts live music sessions throughout the world, has also been acquired by KKR. The DJ and Producer Ikonika and the DJ Beatrice M are two of the artists who have announced their withdrawal from the festival that the company planned to organize in summer. Boiler Room has issued a statement In which he says that the sale has been a decision of his current owners, in which the team has not been able to influence. More festivals. The movement of the groups (and the Very visible action of civil movements such as the known as BDS movement of Boicot, divestments and sanctions against Israel) has encouraged several festivals to join Sónar, as Eldiario.es. This is what Sharemusic!, Organizers of the 90’s, love the twenties or i love reggaeton (“we want to express our total condemnation to the violence that the Palestinian people”), and Rock vineyard (They condemn “without nuances the massacre that the Palestinian people are suffering”). Both, such as Boiler Room and Sónar, clarify that despite the fact that the festivals are owned by KKR, this does not influence the programming or convictions of the teams. Government support. That the music festivals have become a center of attention for their relationship with Israel’s policies are framed in a much narrower observation of different cultural manifestations, with which it seems no longer to serve That “apolitical entertainment”. To the rejection of the bands to the festivals and the dust that has raised the result of Eurovision, the government positions are added. Last Saturday, the Minister of Culture, Ernest Urtasun, said the KKR fund “It’s not welcome” in Spain and commented on the “penetration” at music festivals. After Eurovision, Pedro Sánchez himself requested the Exclusion of Israel from international cultural eventslike the festival itself.

His distance with NASA is narrowing

A long time ago that China set the year From his arrival on the moon by 2030, almost five years after the date initially planned by NASA to put the first woman on the satellite surface. NASA’s plans have been delayed, but China keeps theirs firm; and now the United States advantage in the new space race It is narrower than ever. Context. NASA sent 12 men to the moon Between 1969 and 1972. Apollo missions launched with Saturn V, one of the most powerful rockets in history. Astronauts were in a modular ship that orbit the moon, descended to the surface and returned, with different modules. Unlike the Apollo program, the New Artemisa program It raises the return to the moon with a SLS rocket for takeoff, an Orion capsule to orbit the satellite and a huge commercial ship, the Spacex starship, for the alunication. That the starship is not yet ready is one of the reasons for the delay of the Artemis III mission, now scheduled for not before 2027. Two rockets for two ships. Although its long -term plans are as ambitious as those of the United States (create A manned lunar base that serves as a springboard for future Martian missions), China plans to take astronauts to the moon with a much simpler architecture than Artemis III. He will do it with two consecutive releases of the new CZ-10 rocket, of the state company CASC. The first will launch the Mengzhou ship, where three astronauts will go. The second will launch the Lanyue ship, which will travel empty to the orbit of the moon, where it will be attached to the Mengzhou to access two of the three astronauts, which will then descend on it to the surface. Image published in Baidu that mentions the five launches of the Cz-10 rocket The Chinese lunar calendar. Although the date of the first mooning was already known, we have just known the road map of the Chinese manned space agency (CMSA) thanks to an image that appeared In a Baidu channel that collects Eureka. According to this filtration, the launch of the first Chinese astronauts who will step on the Moon will be the fifth mission of the CZ-10 rocket. The rocket debut is planned for 2027 in a mission without crew called Y1. The first CZ-10 will predictably launch the first Mengzhou ship to the moon. Two options. Most likely, the following year, in 2028, China lance another two CZ-10: the Y2 mission with the first Lanyue Empty ship and the Y3 mission with the second Mengzhou ship; In this case, manned by the first Chinese who will orbit the moon. It would be a general landing essay: the two ships would be attached and decoupled in lunar orbit, with the astronauts present, but Lanyue would go empty to the surface of the satellite to demonstrate that it is safe. It is also possible that the test is carried out directly next to the Y1 mission, coupling the first Lanyue to the first Mengzhou (both without crew), but it would be risky to try the rocket for the first time with a complete essay, which requires two releases. The Apollo 11 of China. Finally, not before 2029, but before the end of 2030, the Y4 mission would launch a Lanyue ship already validated for manned alunage. Shortly after, the mission Y5 would launch the Mengzhou ship with three astronauts, including the first two Chinese who will step on the moon. They will be the Neil Armstrong and Buzz Aldrin from China, although predictably one of them would be an astronaut; Especially if Artemis III continues to delay and the symbolic milestone of putting the first woman on the moon is still available.
