Abstract

We propose and demonstrate a novel and simple signal remodulation ring-based wavelength division multiplexed passive optical network (WDM-PON) scheme with the capability to mitigate the Rayleigh backscattering (RB) beat noise in colorless signal remodulation operation. The effects of RB can be avoided since the backscattering effects and upstream signals travel in opposite directions. Here, 10 Gb/s DPSK downstream is used to launch into reflective optical semiconductor amplifier (RSOA)-based optical network unit (ONU) for signal remodulation at 1.25 or 2.5 Gb/s on-off keying (OOK). Moreover, the network performance has also been analyzed and discussed.
