摘要：

当今，为适应三网融合、智慧城市、基础宽带网建设等一系列国家信息化发展战略的要求，各电信运营商已全面开展以光纤接入替代原有铜线接入的宽带网络改造工作。然而，FTTH的建设和发展是一场革命，涉及一系列新技术和新问题，在规模部署中面临了诸多技术难关需要攻克，其中ODN是FTTH建设和改造中的重点和难点，尤其是如何解决既有住宅建筑内的光缆入户问题。本文从既有住宅建筑光缆入户场景分析入手，围绕如何破解光缆入户难题，在光纤/光缆、光器件、入户器材的选型以及光缆入户施工方法和工艺等方面作了全面的论述。

Abstract:

Facing the national informatization strategies, including triple play, smart city, fundamental broadband network construction and etc, the telecommunication service providers in China are now actively progressing on the replacement of the copper access network with fibers.We believe that the construction and the development of FTTH would be revolutionary and involves a series of new technologies and challenges.We'll have a lot of technical difficulties to conquer during the deployment of FTTH, among which ODN would be the most critical and difficult point, especially that we need to solve the problem of fiber cable dropping in brown areas.Starting with the analysis of the brown area scenario, this article will have a full discussion on the solution of FTTH cable dropping, the selection criteria of fiber/cable, optical devices and equipments, and the fiber dropping techniques.

Key words: FTTH, ODN, KFRP drop cable, dropping scenario, field mechanical fiber connector, bellows
