Cd. Chen et al., FIELD EXPERIMENT OF 10GBIT S, 360 KM TRANSMISSION THROUGH EMBEDDED STANDARD (NON-DSF) FIBER CABLES/, Electronics Letters, 30(14), 1994, pp. 1159-1160
The authors have demonstrated, for the first time, 10Gbit/s transmissi
on over 360km of embedded standard fibre cables. During the five month
long field experiment, the 1.55mum, 10Gbit/s IM/DD system showed long
term 'error free' transmission (less than 10(-16) BER) with an optica
l repeater spacing of 120km (33dB repeater span loss).
