远端OLT与上联交换机如何连接?
提问者:pz1001   |  提问时间:2011-8-24 14:23
FTTH网络中,OLT设备与上联交换机不在同一个站址(约4公里),二者之间是否只需光缆直连,还是需要另外增加有源的传输设备来连接?急!谢谢。
首先看你纤芯资源如何?如果有直达光纤且资源比较富裕的话,站点暂无传输设备的情况下可以直接用光纤直驱方式连接。

长远来看,上联交换机通常是作为OLT汇接用的,通常情况下交换机处是有传输资源的,如果OLT点紧紧是单台设备,那么如果光纤资源足够,直接上联相对来说投资划算些,如果OLT点还放置了其他业务设备,或者以后可能会新增OLT设备,那当然使用传输设备上联能大幅度节约光纤资源,并且以后也要考虑OLT上行板卡扩容问题,加上这么远的距离,长远来看,用传输设备是划算的。
