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
