On WDM RoF–EPON link using OSSB transmission with and without DCF + FBG

A system is presented which uses optical SSB transmission on WDM RoF–EPON link to compensate dispersion and FWM with DCF and FBG. Performance of the system is improved by 8.91% with the use of DCF and FBG for equal spacing between the channels and it is further increased by 9.51% by keeping unequal spacing between the channels. Results are compared for equal and unequal spacing with and without DCF and FBG. BER, Q factor and eye diagrams have been analyzed for evaluating the performance of the system.
