12 300 PS/NM, 2.4 GB/S NONREGENERATIVE OPTICAL FIBER TRANSMISSION EXPERIMENT AND EFFECT OF TRANSMITTER PHASE NOISE

A nonregenerative optical transmission experiment with a chromatic dispersion of more than 10 000 ps/nm is reported for the first time. 2.4 Gb/s externally intensity-modulated optical signals were transmitted over 710 km of nondispersion-shifted optical fiber using ten Er-doped fiber amplifiers with a total net optical gain of 125 dB. In the experiment, although the total chromatic dispersion amounted to 12 300 ps/nm, the power penalty observed was as small as 0.5 dB, and an error floor was not observed. Also, the effect of transmitter phase noise associated with fiber chromatic dispersion was experimentally investigated. © 1990 IEEE
