当今世界，计算机与通信技术高度结合，光纤通信有了长足发展。纵观当今电信的主要技术，光纤和广波的变革极大的提高着信息的传输。进入1993年以后，我国光纤通信已处于持续大反战时期。其特征是大量新技术，特别是网络技术、高速介质接入网（HMAV）光时分复用接入（OTMMA）和波分复用接入（WDMA）、光孤子（solition）、掺铒光纤放大器（EDFA）、SDH产品等开发实用实用化开展大量、深入研究工作。同时，各种专用光纤系统组成及其系统参数测量技术现状，无论是对光纤通信的业主、经销商，还是对光纤通信的广大用户都是重要的。
20世纪70年代末，光纤通信开始进入实用化阶段，各种各样的光纤通信系统如雨后春笋在世界各地建立起来，逐渐成为电信传送网的主要传送手段。近几年来，光纤通信中的各种新技术，新系统也日新月异地发展着，在全球信息高速公路建设中扮演重要角色。
光纤通信是以光波为载波，光纤为传输媒介的通信方式。本次课程设计论文主要介绍光纤系统的基本组成，性能指标，还要对损耗和色散进行预算，用最坏值设计方法来设计高速数字光纤系统。

Abstract
Today’s world, computer and communication technology is highly integrated optical communication has made great progress. In today's major telecommunications technology, fiber and wide wave changes greatly improve the information transmission. Entered after 1993, China's largest optical fiber communications have been in constant war period. Characterized by a large number of new technologies, especially network technology, high-speed media access network (HMAV) optical time division multiplexing access (OTMMA) and wavelength division multiplexing access (WDMA), optical soliton (solition), erbium-doped fiber amplifier ( EDFA), SDH products carry a lot of practical development of practical, in-depth research.At the same time, various special optical system components and their status system parameter measurement techniques, both for the owners of optical fiber communication, distributors, or customers of the fiber optic communications are important.
The late 20th century, 70, entered the practical optical fiber communication phase, a variety of fiber optic communication systems are springing up all over the world set up, has become a major telecommunications transmission network transmission means. In recent years, optical fiber communications in a variety of new technologies, new systems are developing rapidly with the global information highway construction plays an important role.
Optical fiber communication based on the carrier wave, optical fiber as the transmission medium of communication. This paper introduces the course design basic components of optical fiber systems, performance indicators, but also on the loss and dispersion for the budget, with the worst value of the design methods to design high-speed digital fiber-optic system
keywords: optical fiber communication systems, optical fiber, loss, dispersion, fiber optic cable
