目前,密集波分系统已经覆盖了江苏省所有市县,成为江苏有线的骨干层传输网络。随着波分系统的起用,广播和多媒体数据业务占据了大量传输通道,并且需求不断快速增长,仅省干线开通的通道就多达上百条。维护工程师在维护过程中随时需要开通新业务,而大部分市县还没有配备千兆通道测试仪表,掌握一些快速测试新通道的技能非常有用,作者在实践中总结出几种测试波分业务通道的方法,和大家一起分享。
At present, Dense Wave Division System has covered all cities and counties in Jiangsu Province, Jiangsu has become the backbone of the cable transmission network. With the introduction of the WDM system, broadcast and multimedia data services occupy a large number of transmission channels, and the demand continues to grow rapidly, with as many as a hundred channels opened only on the mainline. Maintenance engineers need to open new services at any time during the maintenance process. Most cities and counties are not equipped with gigabit channel test instruments. It is very useful to master some skills of quickly testing new channels. In practice, the author summarizes several channels for testing wavelength division services The way to share with everyone.
