Abstract :
A coherent optical transmission system has been demonstrated using commercial DFB lasers as both transmitter and local oscillator. A receiver sensitivity of ¿51.8dBm was measured at a data rate of 140Mbit/s. The system employs FSK modulation and a three-port, phase-diversity receiver. The effect of source linewidth on receiver bandwidth requirements has been examined.
