光纖通信技術(shù)在電力系統(tǒng)中廣泛應(yīng)用，而且在不斷迅速發(fā)展，但是要想保障電力通信網(wǎng)的可靠，就必須保證網(wǎng)絡(luò)設(shè)備的正常運轉(zhuǎn)，但是設(shè)備的故障在所難免，因此，有必要提高對網(wǎng)絡(luò)設(shè)備的維護能力，出現(xiàn)問題可以及時解決，這樣就能使其更好的為電力的網(wǎng)絡(luò)建設(shè)和信息傳輸服務(wù)。因此，有必要提高通信維護人員的理論水平，提高其的業(yè)務(wù)熟練度，比如：掌握和 SDH 相關(guān)的基本理論知識、出現(xiàn)問題時各種警告代號的含義和解決措施和警告信號的來龍去脈和影響等等，陜西光傳輸設(shè)備SDH華為RET，陜西光傳輸設(shè)備SDH華為RET。同時還要熟悉網(wǎng)絡(luò)的基本概念，陜西光傳輸設(shè)備SDH華為RET，比如系統(tǒng)配置，數(shù)據(jù)的采集和傳輸，同時加強分析故障和解決故障的能力。

設(shè)備都支持帶電熱插拔，拔插法對于故障的處理十分有效，拔插單板的時候要注意正確使用防靜電手鐲，避免由于不使用防靜電手鐲拔插單板時損壞單板，造成不必要的損失。該方法對于一些故障來說快速便捷。 </p> <p> <p> 替換法 </p> <p> 如果拔插法還不能解決故障的話，替換法也是一種選擇。所謂替換法，就是用正常工作的元件去替換被懷疑有故障的元件，從而實現(xiàn)對故障的定位，達到排除故障的目的。這里所提到的元件是指任何設(shè)備，無論是復(fù)雜到一個設(shè)備或者是小到一段線纜。替換法主要用于排除用以傳輸?shù)耐獠吭O(shè)備問題，比如電纜、供電設(shè)備、光纖和交換機等，或者排除某個單站內(nèi)的單板問題。舉例如下：當某一個站的光板出現(xiàn)警告，有可能是收、發(fā)光纖的正反接錯問題?；Q接收線，如果報警消失則說明確實是光纖接反導(dǎo)致的。如若支路板的信號有性能超值或者信號丟失的警告，有可能是中繼線或交換機的問題，可以與其他工作正常的通道互換，若警告轉(zhuǎn)移，則可以證明中繼線或交換機的問題，若不是，則可能是傳輸故障。 </p> <p> 該方法的優(yōu)點是簡單實用。 </p> </p> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="陜西光傳輸設(shè)備SDH華為RET"
