A record-breaking data-rate of 402 terabits per second has been achieved using a bandwidth of 37.6 THz over a standard optical fiber, according to the Photonic Network Laboratory of the National Institute of Information and Communications Technology (NICT). 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, according to a NICT spokesman.
“It is expected that the data-rate of optical transmission systems required to enable “Beyond 5G” information services will increase enormously,” according to the NICT paper. “New wavelengths enable deployed optical fiber networks to perform higher data-rate transmission and extend the useful life of existing network systems. It is also anticipated that new bands can address the increasing demand of next generation communications services by combining with new types of optical fibers.”
In the experiment, NICT expanded dense wavelength division multiplexed transmission to cover all the major transmission bands in the low-loss window of standard optical fibers to enable more than 1,500 parallel transmission channels within the optical bandwidth.
The results of this experiment were accepted at the 47th International Conference on Optical Fiber Communications (OFC 2024) and presented on March 28, at the San Diego Convention Center.
