Compensation of 202 km single-mode fibre chromatic dispersion in 4 Gbit/s optical CPFSK transmission experiment

摘要

Compensation for fibre chromatic dispersion in a coherent transmission system is demonstrated. A 4 Gbit/s optical CPFSK signal at 1.55 mu m is transmitted through a 202 km conventional single-mode fibre. There is 1.8 dB degradation in transmission caused by fibre chromatic dispersion. This degradation has been completely compensated for using a delay equaliser with optical heterodyne detection.
