According to news on March 31, British scientists announced that they have developed a technology that can achieve network speeds of up to 301,000 Gbps through a single standard optical fiber.

英国科学家解锁光纤新频段,实现 301000 Gbps 超高速网络A research team at Aston University achieved this breakthrough by exploiting a new fiber wavelength band. These frequency bands are not currently used by existing fiber optic cables. Noted that other scientists have previously achieved ultra-high-speed networks of more than 1 million Gbps by splitting light pulses into more bands, thereby increasing data transmission rates. However, the Aston University team's paper points out that these solutions often require upgrades to the entire fiber network. "In contrast, our multi-band transmission (MBT) technology requires only system upgrades at the node and operator levels, although the overall bandwidth is limited by the existing standard single-mode fiber (SSMF)," researchers wrote. They also mentioned that the experiment was conducted on optical fiber up to 50 kilometers long. Specifically, the team developed an "optical amplifier and optical gain equalizer" that can utilize E-band and S-band for signal transmission in addition to the commercial C-band and L-band. "Prior to the development of our device, no one had been able to correctly simulate E-band channels in a controlled way," said Ian Phillips, one of the Aston University researchers involved in the project. The research results are expected to provide Internet service providers with a more affordable way to increase the speed of existing fiber-optic networks, "by utilizing more available frequency bands (not just traditional C-band, but also L, S and now "Additional E-band) to increase system capacity can help reduce the cost of providing bandwidth," added Aston University professor Wladek Forysiak, "This is compared to deploying more new fiber optics It is also a more environmentally friendly solution.”
