Abstract : A cost-effective hybrid wavelength division multiplexing (WDM), optical code division multiple access (OCDMA) scheme by sharing single multi-port encoder in central office and using tunable decoders in optical network unit has been proposed and demonstrated in field trial. 111 km error-free transmission of asynchronous, 3-WDM x 10-OCDMA x 10.71 Gbps/user has been achieved with differential phase-shift keying (DPSK) for data modulation and balanced detection. Foreward-error-correction and optical thresholding techniques were not used in the experiment.
