style="max-width: 640px; max-height: 320px;" alt="華為串口光端機(jī)" src="https://tyunfile.71360.com/UploadFile/sztykc/637242899137021484/6354326.jpg"></div><p> SDH 光傳輸設(shè)備故障故障處理方法 </p> <p> <p> 拔插法 </p> <p> 有些故障可以通過拔插單板來排除，現(xiàn)在的 SDH 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(dá)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(jī)等，或者排除某個單站內(nèi)的單板問題。舉例如下：當(dāng)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。互換接收線，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(jī)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(jī)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="華為串口光端機(jī)"

1、SDH傳輸系統(tǒng)在國際上有統(tǒng)一的幀結(jié)構(gòu)，數(shù)字傳輸標(biāo)準(zhǔn)速率和標(biāo)準(zhǔn)的光路接口，使網(wǎng)管系統(tǒng)互通，因此有很好的橫向兼容性，它能與現(xiàn)有的PDH完全兼容，并容納各種新的業(yè)務(wù)信號，形成了全球統(tǒng)一的數(shù)字傳輸體制標(biāo)準(zhǔn)，提高了網(wǎng)絡(luò)的可靠性； </p> <p> 2、SDH接入系統(tǒng)的不同等級的碼流在幀結(jié)構(gòu)凈負(fù)荷區(qū)內(nèi)的排列非常有規(guī)律，而凈負(fù)荷與網(wǎng)絡(luò)是同步的，它利用軟件能將高速信號一次直接分插出低速支路信號，實現(xiàn)了一次復(fù)用的特性，克服了PDH準(zhǔn)同步復(fù)用方式對全部高速信號進(jìn)行逐級分解然后再生復(fù)用的過程，由于**簡化了DXC，減少了背靠背的接口復(fù)用設(shè)備，改善了網(wǎng)絡(luò)的業(yè)務(wù)傳送透明性； </p> <p> 3、由于采用了較先進(jìn)的分插復(fù)用器（ADM）、數(shù)字交叉連接（DXC）、網(wǎng)絡(luò)的自愈功能和重組功能就顯得非常強(qiáng)大，具有較強(qiáng)的生存率。因SDH幀結(jié)構(gòu)中安排了信號的5%開銷比特，它的網(wǎng)管功能顯得特別強(qiáng)大，并能統(tǒng)一形成網(wǎng)絡(luò)管理系統(tǒng)，為網(wǎng)絡(luò)的自動化、智能化、信道的利用率以及降低網(wǎng)絡(luò)的維管費和生存能力起到了積極作用；
