來自左光口的信號1部分落在本地，另1部分繼續(xù)從右光口發(fā)送，這種工作模式叫上下路模式：ADM具有ADM方式的光端機可以組成雙纖自愈環(huán) </p> <p> 雙纖自愈環(huán)的好處 </p> <p> 自愈環(huán)的好處就是，一旦光纜斷了，整個通信不會中斷。光纜正常時，各站間的信息從外環(huán)走端纜后，站1發(fā)向站2方向的信息，改由內環(huán)走，當光纜接好后，網絡自動恢復正常只有具備ADM方式的光端機，才能實現(xiàn)自愈環(huán)。 </p> <p> 光口數(shù)量4：多光口多光方向 </p> <p> 比較好用的光端機是SDH，具有多個光方向但是價格就貴了很多在SDH設備中在詳細論述后面給出1個網絡圖，是各種方式的**。 </p> <p> 深圳騰云科創(chuàng)信息咨詢有限公司，擁有專業(yè)的技術團隊，由 (中興通訊，華為技術)服務10年以上從業(yè)經驗的技術****，并有多名專業(yè)技術人員為您提供專業(yè)的商務技術和專業(yè)解決方案。 </p> <p> <br />
