Nokia Bell Labs announced that its researchers set a world record for single-carrier transmission speeds of 1.52 Tb / s over a portion of a standard 80 km long single-mode fiber. This is four times more than the best serial solutions available on the market now, approximately equal to 400 Gb / s. A clear idea of the record speed gives such a comparison: it is equivalent to the simultaneous streaming of 1.5 million YouTube videos.
According to Nokia Bell Labs, this world record “will further strengthen Nokia’s ability to design networks for the 5G era to meet the ever-increasing demands on data, capacity and latency for the industrial Internet of things and consumer applications.”
The record was set using a new converter, which allows generating signals with a symbol rate of 128 Gbaud and a symbol rate of more than 6.0 bits per symbol and polarization value. At the same time, a world record for data transfer rates for direct-output lasers modulation (DML), which are critical for low-cost, high-speed applications such as data center connections. The record value exceeds 400 Gbit / s for channels up to 15 km long.
