无源波分复用设备应用分析

Application and analysis of passive WDM equipment

针对NB-IoT基站和新建基站采用C-RAN接入,导致城区光缆网纤芯资源紧张,本文提出利用无源波分复用设备方式进行扩容纤芯。无源波分复用设备插入损耗,造成了全程链路衰耗增大。本文理论分析最大传输距离,给出了无源波分复用设备和彩光模块选型,最后结合光缆网现状,提出无源波分复用设备的应用方案。

Aiming at NB-IoT base station and new base station use C-RAN access,lead to the tension of fiber core in optical cable network in urban area,proposed to use the passive WDM equipment of method to expand the core,but passive WDM equipment insertion loss,caused a total link attenuation increase,theoretical analysis of maximum transmission distance,the selection of passive WDM equipment and color light module is given.Finally,combining the status of optical cable network,proposed application scheme of passive WDM equipment.
