Abstract

With the growth of digital technology in the stage of industrial revolution 4.0, the demand for broadcasting large amounts of information to last mile users has increased. Free-space optical (FSO) communication is one of the telecommunication platforms that has shown immense potential in meeting the demand for information broadcasting. In this work, the performance of FSO communication based on wavelength division multiplexing with a data rate of 80 Gbps is investigated through simulations. The configuration of optical amplifiers in the FSO system is set up on the basis of the amplifyforward and amplify-received configurations to expand the network. The investigation is aimed at identifying the best optical signal amplification between an erbium-doped fiber amplifier (EDFA) and a semiconductor optical amplifier (SOA) under an atmospheric channel. Simulation results show that the EDFA performs better than the SOA in terms of the optical signal amplification for eight channels of the C band. The maximum optical propagation path length under the atmospheric channel for the amplify-forward and -received schemes using the EDFA is 1.7 km, with the bit error rate achieved at 10 −6 .

使用光放大器的自由空间光通信系统在放大前向和放大接收配置下的性能
随着数字技术在工业革命4.0阶段的发展,向最后一英里用户广播大量信息的需求也在增加。自由空间光通信是在满足信息广播需求方面显示出巨大潜力的电信平台之一。本文通过仿真研究了数据速率为80Gbps的基于波分复用的FSO通信的性能。FSO系统中光放大器的配置是在放大前向和放大接收配置的基础上设置的,以扩展网络。该研究旨在确定大气信道下掺铒光纤放大器(EDFA)和半导体光放大器(SOA)之间的最佳光信号放大。仿真结果表明,对于C波段的八个通道,EDFA在光信号放大方面优于SOA。使用EDFA的放大前向和接收方案在大气信道下的最大光传播路径长度为1.7km,误码率达到10−6。
