摘要
阐述在广西2004~2005年'村村通'广播电视工程建设中,广西充分利用区光缆干线开口的有利条件,应用1 550 nm光传输系统连接光缆沿途经过的村点,介绍1 550 nm光传输系统长距离传输的优势,并举例说明如何选择光纤网络拓扑结构、如何进行光链路的设计计算以及如何在区光缆干线开口及引接、安装光分路器等.
This paper expatiates how to make the best of the condition to open the municipal optical fiber trunk cable network, applies 1550nm fiber optic transmission system to connect village in Guangxi at 2004 -2005 year. It also introduces the advantage of 1550nm fiber optic transmission system in long distance transmission, illustrates the way of choosing the optical fiber network structure and counting the optical link, as well as how to open and link the optical fiber trunk cable network and install the fiber separate implement.
