Pl. Mason et al., INCREASING THE TRANSMISSION DISTANCE OF A DIRECTLY MODULATED LASER WITH A CHIRPED FIBER BRAGG GRATING DISPERSION COMPENSATOR, Electronics Letters, 31(4), 1995, pp. 281-282
The dependence of dispersion penalty on transmission length has been i
nvestigated in an optical communications system employing a directly m
odulated 2.5 Gbit/s DFB laser source and a fibre grating dispersion co
mpensator. The 2dB penalty transmission distance is similar to 520 km
along standard monomode fibre, representing a great improvement over t
he 150 km range expected for a similar uncompensated system.
