摘　　要：和电信号的引出不同,光信号的引出存在着分路器的分光比损耗太大、引出光信号太弱、与引出光信号的位置有关等问题,使得在光通讯工程实际测试过程中,经常不稳定或不能满足测试需求而失败。本文提出了一种全光有源分路方法,充分发挥了光放大器的作用,可用于光通讯测试时光信号的引出。除了满足测试信号对原信号没有影响的基本要求之外,并且具有插入损耗小、引出信号强、成本较低和与测试光信号格式无关等特点。Different from the electrical signal, the optical signal has many problems in split method, such as too big insertion loss, the weak split test signal, and the test signal concerned in the split position. It is often not stable or can＇t meet the demand and fail in the actual optical communication engineering test process. A full optical design method of active splitter is presented to make full use of the optical amplifiers, which can be used to split test signal in optical fiber network. In addition to meeting the basic requirement of the test signal to have no effect on the original signal, it has a small insertion loss, draws out a strong signal, has a low cost and is unconcerned in test optical signal format etc. With the development of the technology of optical amplifiers, this full optical split method will get more attention.
