Japanese team tops 100 terabits over an optical fibre

Nippon Telegraph and Telephone (NTT) and six partners have established a new world record of 118.5Tb/s for the largest transmission capacity achieved over an optical fibre of standard dimensions.

Though the optical fibre had the same diameter as standard singlemode fibre, its structure was not standard. The design contained four cores (light paths) running along the fibre’s length.

NTT presents FASA concept for virtualised optical access

Nippon Telegraph and Telephone Corporation (NTT) has introduced the Flexible Access System Architecture (FASA) concept, which aims to provide greater flexibility in optical access equipment through the use of network functions virtualisation (NFV).

Instead of using purpose-built hardware, NTT has modularised the various functions of access equipment as much as possible. This is the first time that the modularisation concept has been applied to access equipment, the Japanese company asserts.
