有些故障可以通過拔插單板來(lái)排除，現(xiàn)在的 SDH 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(lái)說(shuō)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(wú)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(shuō)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。 </p> <p> 該方法的優(yōu)點(diǎn)是簡(jiǎn)單實(shí)用。 </p> </p> 湖北光傳輸設(shè)備價(jià)格華為NMU深圳市騰云科創(chuàng)成立于2015年專業(yè)從事通信產(chǎn)品購(gòu)銷以及施工，維護(hù)，產(chǎn)品維修，計(jì)算機(jī)系統(tǒng)集成施工。</p><div

20-60公里。需要更遠(yuǎn)要求時(shí),只要更換光口模塊就可以了。再有就是光口的接頭形式, 較常見的是FC型(圓的)和SC型(方的),定貨是涉及到是否配上尾纖。深圳市騰云科創(chuàng)信息咨詢有限公司以質(zhì)量的服務(wù)、良好的信譽(yù)、雄厚的技術(shù)力量為廣大客戶提供質(zhì)量服務(wù)。我司供應(yīng)中興ZXMP系列產(chǎn)品：ZXMP
