摘 要光纤通信就是利用光纤来传输携带信息的光波以达到通信的目的。光纤通信具有通信容量大、传输速率高、使用寿命长，等诸多特点。因而得到了普遍的应运，其中光放大器是光纤系统中的重要组成部分。光纤放大器是指运用于光纤通信线路中，实现信号放大的一种新型全光放大器。本论文介绍了掺铒光纤放大器的相关理论。首先对光纤放大器的种类进行大致的简介，其次阐述了掺铒光纤放大器的历史和进展，以及对掺铒光纤放大器工作原理进行了介绍又介绍了仿真软件 Optisystem 的使用及功能。重点关注了掺铒光纤放大器的放大过程以及对掺饵光纤放大器各信道增益不平坦问题进行了初步讨论并分析。关键字：Optisystem；光纤通信；掺铒光纤放大器AbstractOptical fiber communication uses optical fiber to transmit information in order to achieve the purpose of communication. Optical fiber communication owns some advantages such as, the communication capacity, high transmission rate, long service life and so on. So it is widely used in optical amplifier and it is an important part of optical fiber systems. Fiber amplifier is a kind of signal amplifier, which is used in optical fiber communication lines to achieve a novel all-optical.This paper introduces a theory of erbium doped fiber amplifier. First, it is introduce the kinds of fiber amplifier. Secondly describes the history and development of erbium doped fiber amplifier, as well as working principle of the erbium-doped fiber amplifier.The functions and the use of simulation software Optisystem are also introduced in this paper. It focuses on the amplification process of erbium doped fiber amplifier and studies and analyzes the problem that the channel gain erbium-doped fiber amplifier is not flat.Keywords: Optisystem;Optical fiber communication; Erbium-doped fiber amplifier目 录1 绪论......................................................................................................................................
