Y. Sorel et al., 10 GBIT S TRANSMISSION EXPERIMENT OVER 165KM OF DISPERSIVE FIBER USING ASK-FSK MODULATION AND DIRECT-DETECTION/, Electronics Letters, 29(11), 1993, pp. 973-975
10 Gbit/s transmission over 116 km of standard dispersive fibre has be
en performed with a simple direct-detection FSK system using a straine
d-MQW VUG DFB high FM efficiency laser directly driven in a mixed ASK-
FSK modulation format. This distance has been extended to 165 km by me
ans of a short length of negative dispersion fibre.
