FBG-Based Large Scale WDM-PON Optical Broadcast Communication System

Abstract

First-class quality and minimum signal errors are the basic requirements of this era, and these requirements are constantly expanding according to the prerequisites of different applications such as real-time communication, network video, and video conferencing. In this research, the FBG-based WDM broadcast communication system is designed to transmit different types of information, such as sound, video, design, text, etc., within the frequency range of 1550 nm. The basic idea behind the framework comes from the passive optical network and adjusts it. The framework is planned in such a way that customers can only identify information of one frequency data at a time. The presentation of the frame is concentrated between 2.5 to 10 gigabits per second, and then the correlation between the Q factor and the bit error rate (BER) is completed based on the results obtained in the bit error analyzer. The framework is simulated with uniform and non-uniform FBG, it can be seen that from obtained results, non-uniform FBG will reduce the dispersion by itself and provide a better- Quality factor of 60. If there is a uniform FBG, then pumping by using a coupler at the same frequency can reduce the effect of dispersion and produce an ideal quality factor of more than 11 for the signal. EDFA amplifiers are associated in the channel to enhance different optical signals at the same time, followed by single-mode fiber (SMF). The framework has been simulated in Opti system’s Opti Wave system software.
