摘要

摘要：伴随着“宽带中国”战略的推进，FTTx大规模部署，同时光纤故障检测需求越来越多，需要一种以较低成本实现PON故障检测，提高运维效率的解决方案。因此，研究了OLT PON端口内置OTDR 技术，分析比较了不同波长方案的实现和成本，重点提出了基于PON 端口内置OTDR 的PON 系统架构，给出PON 端口内置OTDR 技术的测试性能要求以及限制其对设备、通信业务影响的要求，从而使PON端口内置OTDR 能够满足运营商的PON运营检测需求，提高运维效率。

Abstract

Along with the propulsion of the“broadband China”strategy

FTTx has been deployed massively

therefore there are more and more requirements on detecting optic fiber faults

solutions with low cost are needed to detect fiber faults and improve the efficiency of PON operation and maintenance. OTDR integrated in OLT PON port was studied

and the implementation and the cost of different wavelength solutions were analyzed and compared. The PON system architecture based on OTDR integrated in PON port was proposed

and the requirements of OTDR detection ability and the limitation requirements of OTDR effecting the physical parameters of PON port and the communication service were given. The goal is that OTDR integrated in PON port can satisfy the requirements of operators' PON detection

and improve the efficiency of PON operation and maintenance.
