峰峰矿区HFC网络改造方案——从1310nm到1550nm全光网络传输技术方案

HFC Network Transformation Scheme of Fengfeng Mining Area

针对峰峰矿区已拥有的1310nm光网络存在的故障多、可靠性差、管理维护难等问题，讨论了采用1550nm＋EDFA光传输替代1310nm光传输模式的优势，介绍峰峰矿区1550nm全光网络的设计思路和技术方案，该方案使以上问题得以解决。

The 1310 nm Optical Network of Fengfeng Mining Area is now troubled by the frequent faults, low reliability and hard maintenance. This paper discusses the advantage of 1 550 nm ＋ EDFA optical transmission, which may be a substitution of 1 310 nm optical transmission. Then it introduces design and technology scheme of 1 550 nm Optical Network.
