Dual carrier multiplexed M-QAM signals modulated optical SSB transmission over fiber

Abstract

In this paper, a simple hybrid radio-over fiber network that can transmit a different quadrature amplitude modulated (QAM) signals simultaneously over a 50-km fiber link is investigated. Simulation results indicate that a maximum of 162 Mbps-64QAM and 108 Mbps-16QAM signals can be sent simultaneously using Optical Single Side Band (OSSB) generation technique without any dispersion compensation. The proposed dual carrier multiplexing (DCM) architecture may be used for the multi-service transmission in heterogeneous networks. In presence of centralized control and processing, subcarrier multiplexing (SCM) techniques over fiber may provide economical and protocol-transparent solutions for the next-generation hybrid networks.
