Power penalty analysis due to polarisation diversity on 1.2 Gbit/s optical DPSK heterodyne transmission

摘要

An optical DPSK transmission experiment was performed over 100 km at a bit rate of 1.2 Gbit/s using a dual-balanced polarisation-diversity receiver. A high receiver sensitivity of less than -42.8 dBm was achieved and the power penalty due to polarisation diversity was analysed.
