针对太西矿区有线电视网络的升级改造问题,按照统一标准、经济实用的原则,采用二芯光纤设计了一套解决方案并已实施:一级光网为具有自愈功能的环型网络拓扑结构;各分前端的二级光网为星型网络拓扑结构。既保证了有线电视光缆传输高带宽、高质量、低损耗、低成本的特点,又弥补了网络运行的可靠性低、安全性差的不足,是矿区有线电视网络建设中一种较好的方案。 Aiming at the upgrading and reconstruction of CATV network in Taixi mining area, a set of solutions was designed and implemented according to the principle of uniform standard and economy and practicability. The primary optical network is a ring network topology with self-healing function ; The two front-end optical network for the star network topology. It not only ensures the high bandwidth, high quality, low loss and low cost of cable television transmission, but also makes up for the lack of reliability and poor security of network operation. It is a good solution in the construction of CATV network in mining area.
