Abstract

Abstract

Along with the rapid development of broadband technology and network technology ,computer technology, people’s demand for information is more and more big. Thus, put forward the higher requirement of network bandwidth and rate, prompting from low speed to high speed, from Shared to exchange, from narrowband to broadband direction of the development of technology.

Cell FTTX+LAN broadband access network is designed to conform to the development needs of special design a broadband system for intelligentbuildings, such as the body of the nerve, and it has adopted a series of high quality standard materials, combined in a modular way, provides a physicalmedium for the system of intelligent building integration.
