A team of researchers from Japan has set a new world record for internet data transmission speed.
Using commercially available optical fiber, the team achieved a data rate of 402 terabits per second (402 Tbps), about 1.6 million times faster than the average broadband speed in the United States.
High speed data transmission is possible with fiber optic cable.
Led by the Photonic Networking Laboratory at Japan's National Institute of Information and Communications Technology (NICT), the team was able to achieve this feat by building a system that covers all transmission bands of standard optical fibers, as well as deploying various amplification technologies.
NICT claims that this new approach allows them to access previously unused wavelength bands, which could be put to use in future telecommunications networks. “This newly developed technology is expected to make a significant contribution to expanding the communication capacity of optical communication infrastructure as the demand for future data transmission services rapidly increases,” NICT said in a statement summarizing its research.
With the data rate set by the Japanese research team at 402 Tbps, users can imagine that it would allow downloading 12,500 movies in just one second. That's three times the number of movies currently available on Netflix.
Results obtained in laboratory only.
Researchers at NICT have ambitions to eventually extend the transmission range to vast, transoceanic distances, but will need to be cautious about the immediate results of this achievement. While standard optical fiber was used to set the new world record, it was achieved in an optimized laboratory setting. Much more research and a lot of resources will be needed to bring the breakthrough data transmission to the real world, even partially.
Vietnam's international fiber optic cable system must be given priority for modern investment, one step ahead.
According to information on the Electronic Information Portal of the Ministry of Information and Communications (MIC), the Ministry has recently issued a decision approving the "Strategy for developing Vietnam's international optical cable system to 2030, with a vision to 2035".

The strategy clearly states: Vietnam's international fiber optic cable system is an important component of digital infrastructure, and must be prioritized for modern investment, one step ahead, ensuring Vietnam's international connection has super large capacity, super wide bandwidth, safety, sustainability, and enough space for some urban areas to become regional data centers (Digital Hub).

Developing an international fiber optic cable system aims to build autonomy in establishing, deploying, and repairing international fiber optic cables, ensuring the safety of Vietnam's Internet network, and fully meeting the international connection needs for the development of the digital economy, digital society, and national defense and security.
State-owned enterprises pioneered the deployment of international fiber optic cables, promoting domestic and foreign enterprises to participate in investment and construction to quickly develop a breakthrough in Vietnam's international fiber optic cable system.
Target by 2030
Deploy and put into operation at least 10 new submarine optical cable lines with modern technology, bringing the total number of submarine optical cable lines in Vietnam to at least 15 lines with a minimum capacity of 350Tbps.
Deploy and put into operation at least 2 undersea fiber optic cable lines owned by Vietnam, directly connected to Digital Hubs in the region.
Vietnam's submarine optical cable system is deployed and distributed harmoniously in all technically feasible directions: Connecting to the East Sea to the North; connecting to the East Sea to the South; connecting to the southern sea.
Deploy and put into use at least 2 more international land-based optical cable lines, ensuring that the total capacity of international land-based optical cables reaches at least 15% of the actual usable capacity of the submarine optical cable system.
