A Rayleigh backscattering noise eliminated long-reach, single-fiber, full-duplex, centralized WDM-PON with 10-Gb/s DPSK downstream and remodulated 2.5-Gb/s OOK upstream using optical carrier-suppressed sub-carrier-modulation and optical interleaver is proposed. Experimental demonstration shows error-free transmission over 115km SMF-28 with less than 2dB power penalty.
Simple WDM-PON testbed with centralized-lightwave using single-arm IM to provide 10 Gb/s data and 2.5 Gb/s digital video downstream and 2.5 Gb/s upstream data has been demonstrated. After 20 km SSMF, power-penalty for all channels is less than 0.5dB.
