M. Nakazawa et al., FIELD DEMONSTRATION OF SOLITON TRANSMISSION AT 10GBIT S OVER 2000KM IN TOKYO METROPOLITAN OPTICAL LOOP NETWORK/, Electronics Letters, 31(12), 1995, pp. 992-994
Experimental field transmissions of solitons at 10Gbit/s over 2000km h
ave been successfully demonstrated using part of the Tokyo metropolita
n optical loop network. The network is composed of conventional disper
sion-shifted 200 core optical fibre cable which was not originally int
ended for soliton transmission. However, with the dispersion-allocated
soliton transmission technique, an error-free 13ps soliton data train
was successfully transmitted over 2000km. The power penalty at a BER
of 10(-10) was 3.1dB.
