(2)復(fù)用光纖保護(hù)：
光纖與縱聯(lián)保護(hù)(如：7SL32、WXH-11、CSL101、WXH-11C保護(hù))配合構(gòu)成復(fù)用光纖縱聯(lián)保護(hù)。采用允許式，保護(hù)裝置發(fā)出的允許信號和直跳信號需要經(jīng)音頻接口傳送給復(fù)用設(shè)備，然后經(jīng)復(fù)用設(shè)備上光纖通道。優(yōu)點是：接線簡單，利于運行維護(hù)。帶路進(jìn)行電信號切換，利于實施。提高了光芯的利用率。缺點是：中間環(huán)節(jié)增加，而且?guī)非袚Q設(shè)備在通信室，不利于運行人員巡視檢查，通信設(shè)備有問題要影響保護(hù)裝置的運行。
