Abstract

The main aim of the proposal is to enhance overall capacity of the passive optical network, by increasing Wavelength Division Multiplexing (WDM) channels. The objective of this paper is to demonstrate the technique to generate Optical Flat comb spectrum (OFCS) with the help of Amplitude Modulator (AM) and Single Drive Mach Zehnder Modulator (SDMZM). The OFCS generated through this technique will have 51 spectral lines with very less power difference between them. Both (AM and MZM) modulators are driven by the same RF frequency of 30 GHz and proper DC biasing is given for MZM to get very flat spectral carriers. The OFCS generated by this method can be used in WDM-PON system which can serve large number of users. Each carrier out of 51 spectral lines is capable of supporting greater than 10 Gbps Quadrature Amplitude Modulation based data with the help of Orthogonal Frequency Division Multiplexing (OFDM) sub-carriers.
