文档介绍：某小区光纤有线电视网络的设计
摘要
有线电视在目前住宅建设中是必备的,随着广播电视的飞速发展,以及信息化的发展要求,光纤有线电视的高速应用和普及,成为整个有线电视和通讯网络的瓶颈,因此迫切需要找到一种有利于业务综合发展方式。
光纤有线电视网络技术的发展,是网络向综合化、多功能、数字化发展的必要要求。即通过对光纤CATV 网络的改造,可以使其升级为光纤/同轴电缆混合(HFC)系统,或者将HFC与光纤数字技术相结合构成交互式数字视频(SDV)系统,实现在同一网络中传送有线电视、电话综合业务。
应用光纤传输有线电视信号,采用分布式HFC的网络结构,增加了小区有线电视网络的功能,使有线电视网络能够为人们提供期待己久的新业务。同时也为当地发展综合业务数字电视奠定了良好的基础。

Abstract
Cable TV in the current housing construction is necessary, along with the rapid development of radio and television, as well as requirements for the development of information technology, high-speed fiber optic cable usage and ration, as the entire cable work bottlenecks, there is an urgent need It conducive to business to find prehensive approach to development.
Optical fiber work technology development is integrated to work, multi-function, digital development of the necessary requirements. That is, through the transformation of optical work, it can upgrade to a fiber / coaxial cable mixed (HFC) system, or HFC and optical digital interactive technology bining a digital video (SDV) system, to achieve the same Cable work transmission, telephone integrated services.
Applications transmitting cable television signals, distributed by the work structure, an increase of the functions of district cable works, cable works to provide people with long been looking forward to the new business. But also for the local development of an integrated service digital TV laid a good foundation.
Key words: optical fiber cable; transmission image quality; work;
