一种10M/100M自适应以太网光纤收发器的实现

 摘要：光纤收发器的作用是将我们要发送的电信号转换成光信号，并发送出去，同时，能将接收到的光信号转换成电信号，输入到我们的接收端，本文分别从光纤收发器主要元器件的选型、线路板抗电磁干扰、方案性能测试几个方面进行了阐述。此收发器不仅能用在100Mbps系统中，而且能用于现有的大量10Mbps的设备环境中，能够实现两者间的自适应连接。与同类方案相比具有功能更强、体积更小、成本更低的优点，在实践中得到了很好的应用。

A Realization of 10M/100M Self-Adapting Ethernet Media Converter

Abstract: The role of the fiber-optic transceiver is to convert an electrical signal into an optical signal, and send out; and at the same time, it is able to convert the optical signal which is received into an electric signal, and input to the receiver. The selection of the main components, PCB design, and performance tests are described in this paper. This converter can be used not only in the 100Mbps system, but also for a large number of existing 10Mbps device environment, and achieve connection can be achieved between them. Comparing with the same kind of products, it features more powerful in function, smaller in volume, less power consumption and lower cost, and Obtained the very good application in practice.
