Abstract :
A 1.244 Gbit/s 32 channel transmission experiment is demonstrated by using a shelf-mounted continuous-phase FSK optical heterodyne system. Stable 121 km fibre transmission is achieved with sensitivity ranging from -45.1 to -44.2 dBm at a bit error rate of 10-9. This is made possible by employing channel spacing stabilisation, optical tuning and polarisation diversity reception.
