Japan announced that a team of engineers from the National Institute of Information and Communication Technology (NICT) research team has achieved a record Internet speed of 319 terabits per second (Tb/s), twice the previous world record.
The previous Internet speed world record was set in 2020, when British and Japanese engineers collaborated to make 178 Tb/s connection a reality. However, today’s announcement ignored this engineering feat, which almost doubled the old record.
Scientists at NICT use optical fiber, a small tube that uses light to transmit information, which is needed to achieve recording. Ordinary copper cables cannot carry such speeds and require more complex infrastructure to work.
In order to achieve this record, the team must use some special add-ons that are only familiar to highly skilled and educated laser engineers. “We demonstrated the cyclic transmission of 552 x 25 GHz spaced channels, covering the S, C and L bands >120 nm in a 125μm diameter 4-core fiber, and measured a decoding throughput of 319 Tb/s at 3001 km.” , As a submitted paper International Optical Fiber Communication Conference Say.
They used 552-channel comb lasers emitting various wavelengths. Subsequently, these optical streams are processed and amplified by a new type of thulium and erbium-doped fiber amplifier. The process after amplification is conventional Raman amplification. Although the working principle of this method is very complicated, the final result is that the speed of realization is a huge breakthrough.
The team can maintain this speed over 3000 kilometers and maintain the bandwidth it creates without sacrificing performance. Engineers said that even ordinary fiber optic infrastructure can support these types of speeds, but some modifications need to be made first.
It is almost impossible to imagine that this raw bandwidth will enter our homes and offices. However, the applications and possibilities will be endless. However, we will not hold our breath and wait for the local ISP to implement this technology as soon as possible.
