有线电视宽带接入网技术的应用

BROAD BANDWIDTH ACCESS BY CATV CABLE MODEM TECHNOLOGY

为解决网络最后一公里问题 ,研究了有线电视宽带接入技术 .实现有线电视宽带接入网的主要困难在于噪声控制、网络优化和调制技术的选择 .分析了 S- CDMA技术的优势 ,并结合某高校实际做出选择 .通过对网络噪声的分析和实际测量 ,提出采用“小分损组网技术”和“高衰配平阻噪技术”.工程实践表明 ,采用 S- CDMA调制 ,并采用 Cable

This paper discusses the CATV broad bandwidth access technology.The main problems of building a CATV access network are noise control,network reconfiguration,and the choice of cable modem.We choose the S CDMA by Terayon according to Tianjin University network environment.The running experience of the CATV access network shows that high speed two way network transport is possible.
