Abstract
In this paper, the performance of WDM Ethernet Passive Optical Network (EPON) with radio over fiber (RoF) optical link is enhanced by using a square root module (SRm) at the receiver side. We have proposed that a square root (SQRT) module compensates the square law characteristics for improving the performance of WDM RoF-EPON. The improvement in the performance has been reported four times for successful transmission over the distance of 20km that has been witnessed by BER, Q factor and eye opening. Moreover the significant improvement in the signal power has been noticed which is 4.675, −47.118dBm with SRm and −20.563, −84.896dBm without SRm for ONUs and OLT respectively.
