Reduction of signal-induced Rayleigh noise in a 10 Gb/s WDM-PON using a gain-saturated SOA

We demonstrate mitigation of signal-induced Rayleigh-beat-noise in a carrier-distributed WDM-PON using a gain-saturated SOA. The required signal-to-Rayleigh power was reduced by 11dB thereby enabling 10Gb/s error-free transmission in a 64 way-split, 20km reach PON.
