設(shè)備都支持帶電熱插拔，拔插法對(duì)于故障的處理十分有效，拔插單板的時(shí)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(shí)損壞單板，造成不必要的損失。該方法對(duì)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(shí)現(xiàn)對(duì)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(gè)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(gè)單站內(nèi)的單板問題。舉例如下：當(dāng)某一個(gè)站的光板出現(xiàn)警告，有可能是收、發(fā)光纖的正反接錯(cuò)問題?；Q接收線，如果報(bào)警消失則說明確實(shí)是光纖接反導(dǎo)致的。如若支路板的信號(hào)有性能超值或者信號(hào)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。

style="text-indent:25px">光纖通信技術(shù)的特點(diǎn)--損耗低,中繼距離長。目前實(shí)用石英光纖的損耗可低于0.2dB/km,比其他任何傳輸介質(zhì)的損耗都低,若將來采用非石英系極低損耗光纖,其理論分析損耗可下降至109dB/km。由于光纖的損耗低,所以能實(shí)現(xiàn)中繼距離長,由石英光纖組成的光纖通信系統(tǒng)比較大中繼距離可達(dá)200多千米,由非石英系極低損耗光纖組成的通信系統(tǒng),其比較大中繼距離則可達(dá)數(shù)千甚至數(shù)萬千米,這意味著通過光纖通信系統(tǒng)可以跨越更大的無中繼距離,對(duì)于一個(gè)長途傳輸線路,由于中繼站數(shù)目的減少,系統(tǒng)成本和復(fù)雜性可**降低。專業(yè)銷售SDH光傳輸設(shè)備，PTN設(shè)備，OTN設(shè)備。認(rèn)準(zhǔn)深圳市騰云科創(chuàng)信息咨詢有限公司！</p><div
