<p> 可見SDH光端機是大容量光端機. </p> <p> 155,和622是SDH體制里應(yīng)用**多的光端機。 </p> <p> 一般的光端機沒有以太網(wǎng)接口, 帶以太網(wǎng)接口的光端機是近2年市場的新需要 </p> <p> 用1個E1信道可以傳10M以太網(wǎng)信號,用4個E1信道可以傳100M以太網(wǎng)信號 </p> <p> 一般的光端機沒有V35接口 </p> <p> V35接口也是近2年的市場需要 </p> <p> V35接口是1種同步數(shù)據(jù)接口,速率是NX64kb/s. </p> <p> 通常用1個E1傳輸1路V35接口。 </p> <p> 一般光端機都有輔助信道。輔助信道是低速的異步數(shù)據(jù)接口,如RS232勤務(wù)電話,用于站間聯(lián)絡(luò)，海南SDH光傳輸設(shè)備華為CKU,實際上很少使用很便宜的光端機沒有勤務(wù)電話,有的甚至沒有異步數(shù)據(jù)。 </p> <p> 網(wǎng)管,就是計算機網(wǎng)絡(luò)管理,也叫集中監(jiān)控。將所有站的光端機的運行狀態(tài)信息都接入總局網(wǎng)管室的網(wǎng)管計算機里,就是網(wǎng)管。 </p> <p> 一般PDH光端機沒有網(wǎng)管系統(tǒng)，只能做TM,即點到點網(wǎng)絡(luò)，只有1個光口。 </p> <p> 一般SDH光端機都有網(wǎng)管系統(tǒng)，海南SDH光傳輸設(shè)備華為CKU，即可以做TM方式,也可以做ADM方式,因此可以組成自愈環(huán)網(wǎng)絡(luò)。 </p> <p> 3個以上光方向的工作方式叫DXC，海南SDH光傳輸設(shè)備華為CKU,就是交叉連接方式。 </p> <p> <br />

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(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?；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><p style="text-indent:25px">光纖在光傳輸中的應(yīng)用根據(jù)傳輸設(shè)備的不同,光纖線路在光傳輸網(wǎng)絡(luò)中主要有兩種應(yīng)用:一種為數(shù)字傳輸,一般為PDH、SDH制式。PDH目前較少用于廣播電視傳輸,多用于數(shù)據(jù)傳輸。SDH多用于組建干線傳輸網(wǎng),也是目前廣電系統(tǒng)采用的傳統(tǒng)模式。另一種為AM模擬傳輸,AM模擬有線電視光傳輸系統(tǒng)又可分為直接調(diào)制調(diào)幅和外調(diào)制調(diào)幅系統(tǒng)。直接調(diào)制調(diào)幅系統(tǒng)是半導(dǎo)體、激勵器直接將光強度調(diào)制,將調(diào)頻電信號轉(zhuǎn)換成調(diào)幅光信號進行傳輸。(DFB)激勵器,其光譜線窄、線性好、輸出功率高、光波長為1310nm,目前使用**多,適用于中短距離傳輸。為廣播電視系統(tǒng)傳輸?shù)闹鞴饫w的連接分為熔接和磨接,無論何種連接都會產(chǎn)生接頭損耗。1310nm的光纖衰減系數(shù)為0.35dB/km。無論信號傳輸遠近,光纜的連接都需要進行光纖熔接,其接頭熔接損耗一般在0.05dB以下。因此在計算光纖自動損耗時還應(yīng)考慮接頭和其他損耗(2km一般取1dB)。深圳市騰云科創(chuàng)專業(yè)從事華為傳送網(wǎng)設(shè)備,中興承載網(wǎng)設(shè)備光端機等通信產(chǎn)品購銷！</p><div
