(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(diǎn)是：接線簡單，利于運(yùn)行維護(hù)。帶路進(jìn)行電信號切換，利于實(shí)施。提高了光芯的利用率。缺點(diǎn)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(yùn)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(yùn)行。

使用安全PLC/DCS 及安全網(wǎng)絡(luò)的優(yōu)點(diǎn)包括:
1 機(jī)械控制更大的集成性和靈活性
2 當(dāng)標(biāo)準(zhǔn)控制層智能化時(shí)，能夠進(jìn)行更好更容易的故障診斷
3 更快、更方便的維護(hù)
4 減少安裝、調(diào)試以及重新配置的費(fèi)用
5 與對于邏輯單獨(dú)使用安全繼電器相比，降低了設(shè)計(jì)和硬件成本
