PROJECT TITLE :

Performance of WDM-OFDM for Using Unequalized Optical Frequency Comb

ABSTRACT:

Optical Frequency Comb Generation (OFCG) technique employing a Mach Zehnder modulator (MZM) allows to diminish cost of an optical access network based mostly on Wavelength Division Multiplexing (WDM), because it simply desires one supply for generating several optical carriers. But, the unequalized comb power is a limitation for the performance of the network. So as to take care of its simplicity and low price, we propose to mix WDM with Orthogonal Frequency Division Multiplexing (OFDM). This answer permits changing the quantity of bits per carrier, being adaptive to many link impairments. An algorithm based mostly on bit‒loading strategies maximizes the transmission rate and mitigates the results of the unequalized channels on a WDM network. The simulation results show the efficiency of the adaptive algorithm to extend the channel capability up to 35 Gbps over five unequalized WDM channels.
