Japanese engineers create revolutionary fiber optic cable with record bandwidth

A team of engineers from Japan has achieved a significant breakthrough in data transmission technology by developing a new type of fiber optic cable with extremely high bandwidth. Japan’s National Institute of Information and Communications Technology(NICT) transferred data at 22.9 petabits per second (Pbps), according to the NewAtlas report. For comparison, the current estimate of global Internet traffic is about 1 Pbps, which means that the new cable is 22 times higher than this figure.

This record was achieved through the use of several innovative technologies. The cable contains 38 fiber optic cores, each of which transmits data in three modes. This allows the use of a total of 114 spatial channels, and each of these channels consists of 750 wave channels in three bands (S, C, L), which creates a total bandwidth of 18.8 THz.

The transmission speed of 22.9 Pbps significantly exceeds the previous record set in 2020. In addition, the team believes that further optimization of the error correction system could even increase this speed to 24.7 Pbps.

However, the use of this technology in everyday life is currently limited. Decoding data transmitted at this speed requires complex signal processing, which requires the use of specialized MIMO receivers in the network. In addition, the high cost and complexity of mass production of such cables pose additional challenges.

This technological breakthrough opens up new horizons for the future of the Internet and data transmission, although its practical application may be limited in the near future due to the technical and financial challenges mentioned above.
