配网自动化通信PON中继器的研究

本文介绍了一种用于组建基于EPON的双环自愈网的EPON中继器,内部包含两路OEO放大整形电路,可同时对两路EPON信号的下行和上行光信号放大整形,增强光信号功率,延长通信距离,提高环路所能接入的ONU数量,增强了网络部署的灵活性和方便性。

This article introduces an EPON repeater which is used to build a dual loop self-healing network based on EPON.It contains two channels of OEO amplification and shaping circuit,which can amplify and shape the downlink and uplink optical signals of two EPON signals at the same time,enhance the optical signal power,extend the communication distance,increase the number of onus that can be accessed by the loop,and enhance the flexibility and convenience of network deployment.
