Field demonstration of soliton transmission at 10 Gbit/s over 2000 km in Tokyo metropolitan optical loop network

Abstract

Experimental field transmissions of solitons at 10 Gbit/s over 2000 km have been successfully demonstrated using part of the Tokyo metropolitan optical loop network. The network is composed of conventional dispersion-shifted 200 core optical fibre cable which was not originally intended for soliton transmission. However, with the dispersion-allocated soliton transmission technique, an error-free 13 ps soliton data train was successfully transmitted over 2000 km. The power penalty at a BER of 10-10 was 3.1 dB.
