Abstract :
Employment of optical frequency shift keying (OFSK) as the downstream modulation format in a WDM passive optical network is proposed. The upstream OOK (on-off keying) transmitter at the ONU (optical network unit) can be realised by remodulating the constant-intensity downstream OFSK signal power with the upstream data. Transmission and remodulation of 2.5 Gbit/s downstream and upstream signals were successfully demonstrated.
