Abstract
Employment of optical frequency shift keying (OFSK) as the downstream modulation format in a WDM passive optical network is proposed. The upstream OOK transmitter at the ONU 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.Keywords
