🌐 A world record for data transmission speed in a standard commercially available optical fiber was reached in Japan. An international joint research group on head of the Photonic Network Laboratory of the National Institute of Information and Communications Technology (NICT) based in Tokyo-Japan, also including Aston Institute of Photonic Technologies (AIPT), Nokia Bell Labs, USA, Amonics, Hong Kong, University of Padova, Italy and University of Stuttgart, Germany. It was demonstrated a record-breaking aggregate optical transmission bandwidth of 37.6 THz to enable a new data-rate record of 402 terabits per second (Tb/s) in a standard commercially available optical fiber.
This record data-rate was achieved by constructing the first optical transmission system covering all the transmission bands (O,E,S,C,L and U) of the low-loss window of standard optical fibers. The system incorporates various amplification technologies, some developed for this demonstration, including six kinds of doped fiber optical amplifiers and both discrete and distributed Raman amplification.
It beats their previous record of 301 terabits or 301,000,000 megabits per second using a single, standard optical fiber. This speed is over 100 million times faster, if it is compared to the internet connection speed recommendations of Netflix, of 3 Mbit/s or higher, for watching a HD movie. The speed was acquired by using a wider spectrum, using six bands rather than the previous four, which increased capacity for data sharing. Generally just one or two bands are used.
“The newly developed technology is expected to make a significant contribution to expand the communication capacity of the optical communication infrastructure as future data services rapidly increase demand”.
