Abstract

We propose a novel wavelength-division-multiplexed passive optical network (WDM-PON) architecture with enhanced tolerance toward chromatic dispersion where a DPSK-modulated downstream signal with constant intensity is remodulated at the ONU side with a return to zero (RZ-DPSK). Driving the downstream modulator with a 50% RZ data enabled us to employ the pulse carver at the ONU for both removing downstream data and generating the optical RZ signal for upstream. This offers an attractive alternative to earlier proposed schemes as it allows us to use full modulation depth (FMD) and balanced detection for downstream data restoration. We experimentally demonstrate the system with both balanced and single-ended detection at 2.5Gb/s. Error-free operation has been achieved along a 20Km single mode fiber without dispersion compensation.
