First , the background and significance of the project are introduced . the pin photo - detector and its application in the laser measure are discussed 首先，阐述了本文的研究背景、目的和意义，介绍了pin光接收器及其在激光测距中的应用状况。
Return optical receiver 16 - way receiving zhsr - 200 at most , can be equipped with 8 forward receiver module , 1 receiver module can 2 way return optical signal , then send out 1 rf after combination 最多可配置8个反向光接收模块， 1个接收模块能接收2路反向光信号，经混合后输出1路射频信号。
One forward optical receiver module takes one slot , after power double - amplification inside , send out 1 way rf signal 104dbuv and 1 way level checking signal , or two - distribution output 一个正向光接收器模块占一个槽位，内置功率倍增放大，输出1路射频信号104dbuv和1路电平检测口，或二分配输出
The company develops series products of the catv photoemission equipment and the light receiving equipment and most early obtains the certificate to enter the net from original bureau of broadcast and tv 公司开发生产的catv光发射设备、光接收设备系列产品最早获得原广电部入网证书、被国家科委评为高科技新产品。
Due to the urgent demand of domestic user and the fact that the test system of photo - detector is mainly imported from abroad , we developed a set of test system . it has great value of theory and utility 针对目前光接收器测试系统主要依赖于进口的现状，以及国内的迫切需求，本文研制了一套实用的光接收器测试系统，有较高的理论意义和实用价值。
Pin photo - detector is used extensively in fiber communication and national defense . it has crucial value , it ' s characteristics influence the quality of the whole system . so it needs to be tested strictly Pin光接收器在光纤通信、国防军事等领域广泛应用，有极其重要的价值，其性能关系到应用系统的整体质量，因此须对其进行严格的性能检测。
Second , the whole process of developing the test system is introduced . the design of optical structure , mechanical structure , laser , fiber , monitor software and database software are all presented in detail . third , the process of debugging and test is introduced 其次，对pin光接收器测试系统研制的全过程进行介绍；重点论述了光学、机械结构的设计、激光光源、光纤的选择和应用以及自动测试和集中监控应用软件的集成和数据库软件的编制。
