光纤接收机码间串扰测试

光纤通信系统的测试仪表大多建立在光学和电子学原理之上,因此系统复杂、设备昂贵.本文给出了不需要这些昂贵测试设备却又能进行测试的方法.本文首先从原理上探讨了光纤接收机码间串扰的抑制方法,并从中得到了用示波器观察光纤接收机码间串扰的启发,最后介绍了两种关于光纤接收机码间串扰的简单测试法,为测试设计、测试执行人员在进行光纤接收机码间串扰测试时提供了一种思路.

Test of inter symbol interfere of the optical fiber receiver

The optical fiber corresponds by letter the test gauge of the system mostly based on the optics and electronics principle,so system is complicated,and the equipments is expensive.Can we have to do the test but not need these expensive test equipmentses?This paper gave the affirmative answer.It explores the principle of restraining method of the ISI(inter symbol interfere)of the optical fiber,and gets the elicitation of the ISI,finally introduces the two kinds of testing methods.
