密集波分復用器(DWDM)應用方案

上傳時間:2020-06-05   瀏覽次數:4647

1、DWDM點對點應用方案


采用DWDM點對點傳輸

點到點的拓撲中,設備利用有限的光纖資源,復用出幾倍于原有的帶寬來實現兩點之間多業務的雙向匯聚,比CWDM具有更大的帶寬容量


2、DWDM鏈狀組網


采用OADM鏈狀組網

采用波分復用終端設備(MUX/DMUX)和光分插復用設備(OADM)配合,上下幾路波長,構架出城域光通信中的鏈狀網絡。


3、DWDM環網組網


DWDM組環保護

利用多個波通道在雙纖資源中實現業務對稱環網,主路由業務中斷,業務自動切換至備用路由,實現業務側和復用段組環保護,保證業務穩定傳輸,提高了系統的穩定性,同時DWDM各通道相互獨立,相互通訊無干擾,提高業務容量,節省光纖資源的同時,保證了業務信號的安全性、穩定性,充分體現波分復用的優勢。鎮江波分系統設備.
