Paper Title
Performance Evaluation of 16qam Optical Network for WAN Communication

A secure, reliable and flexible wide area network (WAN) is crucial in today’s fastest growing technological era. By incorporating optical and wireless technology, the Critical WAN Infrastructure solution enables the convergence of all traffic (voice, video and data) onto a single network with enhanced security and prioritization capabilities. In this paper, we propose the design of an all-optical wide area network for P2MP communication with the help of 16QAM modulation technique. Dispersion compensation (DC) has been used to lessen the consequence of intersymbol interference (ISI) as well as the signal degradation due to overlapping of signals in the optical network. Maximum Q-factor achieved for a distance of 20, 30 and 40Km is 9.1, 8.5 and 7.7 respectively. Keywords - WAN, PON, 16QAM, Q- FACTOR, ISI, P2MP
