Future Generation Optical Network for Wired and Wireless Networks Based on OFDM using a Comb Source

Abstract

In this study it is focused to design an architecture for the future optical networks based on PON ( Passive Optical Network) called as FGON (Future Generation Optical Network). The FGON improves the efficiency and reliability of optical networks in providing a seamless data transmission network by integrating the three core concepts namely WDM, PON and OFDM. The proposed network also supports ROF (radio over fiber) for extended coverage of optical signals through wireless in unfavorable domains. In the FGON the input signals are given using a unique technique of creating a dense signals using WDM by creating a uniform comb like structure by using a dual arm Mach Zender Modulator based circuit whose output has nine flat comb structures and then the modulation technique of OFDM is used for enabling the WDM-OFDM-PON We study the performance of the signals generated by the comb structure in a ROF based OFDM-PON simulation network where out of the nine generated signals seven are used for wired network and one for wireless network and one for common uplink channel the various parameters such as the received signal strength FGON network, BER (Bit Error Rate) are noted and analyzed, and the received signals propagation characteristics of the FGON is noted which will be suitable for next generation optical access.
