PON技术及其在铁通接入网中的应用

PON Technique and Its Application in CRC'Access Network

本文介绍宽带光纤网络的主流接入技术——无源光网络(PON)技术,比较几种PON技术的利弊及适用范围,采用PON技术的优势,以及接入网光进铜退的几种应用模式。

The key broadband access technology of the optical fiber network-Passive Optical Network（PON） are demonstrated in this paper,where the pros and cons of several PON techniques and their proper applications are compared.By utilization of the advantages of the PON techniques,a number of application patterns of the optical fiber substitution for trunk copper cable have also been illustrated.
