On WDM RoF–EPON link using OSSB transmission with and without square root module

In this paper, we have proposed a technique for the generation of OSSB transmission with carrier for WDM Ethernet Passive Optical Network (EPON) with Radio over Fiber (RoF) optical link. The performance of the system is further enhanced by using a square root module (SRm) at the receiver side. The suppression of 5 dB in carrier and 10 dB in the sidebands has been shown. The improvement in the performance has been reported three times for successful transmission of OSSB as compared to ODSB over the distance of 20 km and it is further enhanced by two times with the use of SQRT module and that has been witnessed by measuring BER and eye opening.
