摘要

We investigate the principles of optical phase remodulation and demonstrate its application in a future-proof 10 Gb/s/channel wavelength-division-multiplexed (WDM) passive optical network to realize a colorless optical network unit and bidirectional transmission over a single fiber.The modulation depth of downstream differential phase-shift keying is properly reduced to facilitate phase remodulation and Rayleigh noise mitigation.For both downstream and upstream 10 Gb/s signals,error-free transmission via a 20 km single-mode fiber is demonstrated without dispersion compensation operation.
