Complete suppression of FWM in ultra dense WDM-PON optical networks using centralized light source

Abstract

In this paper, a novel technique to completely eliminate FWM has been introduced. Alternative circular polarizer have been used to change the polarization of incoming pulses into left-hand and right-hand polarizations before multiplexing in UDWDM optical network with centralized light source. System’s performance have been calculated on the bases of Q factor, optical signal to noise ratio, received power and bit error rate. All simulation has been performed in OptiSystem.
