的改進(jìn)版，它的發(fā)明是電信傳輸體制的**之一，湖南SDH光傳輸設(shè)備華為NMU，原因在于它可以對(duì)同步信號(hào)進(jìn)行傳送、分插、交叉連接和復(fù)用，不僅可以通過(guò)衛(wèi)星、光纖，還可以微波等進(jìn)行傳送，是一種新的傳輸體制。SDH 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，湖南SDH光傳輸設(shè)備華為NMU，就必須保證網(wǎng)絡(luò)設(shè)備的正常運(yùn)轉(zhuǎn)，但是設(shè)備的故障在所難免，因此，有必要提高對(duì)網(wǎng)絡(luò)設(shè)備的維護(hù)能力，出現(xiàn)問題可以及時(shí)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，湖南SDH光傳輸設(shè)備華為NMU，有必要提高通信維護(hù)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(shí)、出現(xiàn)問題時(shí)各種警告代號(hào)的含義和解決措施和警告信號(hào)的來(lái)龍去脈和影響等等。同時(shí)還要熟悉網(wǎng)絡(luò)的基本概念，比如系統(tǒng)配置，數(shù)據(jù)的采集和傳輸，同時(shí)加強(qiáng)分析故障和解決故障的能力。 </p> <p> <br />

光纖接口是用來(lái)連接光纖線纜的物理接口。通常有SC、ST、FC等幾種類型，它們由日本NTT公司開發(fā)。 </p> <p> FC是Ferrule Connector的縮寫，其外部加強(qiáng)方式是采用金屬套，緊固方式為螺絲扣 </p> <p> ST接口通常用于10Base-F， </p> <p> SC接口通常用于100Base-FX。 </p> <p> RJ-45接口是以太網(wǎng)**為常用的接口，指的是由IEC（60）603-7標(biāo)準(zhǔn)化，使用由國(guó)際性的接插件標(biāo)準(zhǔn)定義的8個(gè)位置（8針）的模塊化插孔或者插頭。 </p> <p> RS-232-C接口是**常用的一種串行通訊接口。它是在1970年由美國(guó)電子工業(yè)協(xié)會(huì)聯(lián)合貝爾系統(tǒng)、調(diào)制解調(diào)器廠家及計(jì)算機(jī)終端生產(chǎn)廠家共同制定的用于串行通訊的標(biāo)準(zhǔn)。它的全名是“數(shù)據(jù)終端設(shè)備和數(shù)據(jù)通訊設(shè)備之間串行二進(jìn)制數(shù)據(jù)交換接口技術(shù)標(biāo)準(zhǔn)”。該標(biāo)準(zhǔn)規(guī)定采用一個(gè)25個(gè)腳的DB25連接器，對(duì)連接器的每個(gè)引腳的信號(hào)內(nèi)容加以規(guī)定，還對(duì)各種信號(hào)的電平加以規(guī)定。（多用DB9）。RJ-11接口就是我們平時(shí)所說(shuō)的電話線接口 </p> <p> RJ-11是用于西部電子公司（Western Electric）開發(fā)的接插件的通用名稱。其外形定義為6針的連接器件。原名為WExW，這里的x表示“活性”，觸點(diǎn)或者打線針。 </p> <p> <br /> </p><p> 怎么看光端機(jī)的性能優(yōu)劣 </p> <p> 組網(wǎng)方式：能不能構(gòu)成自愈環(huán)。 </p> <p> 光口數(shù)量1：點(diǎn)到點(diǎn)方式 </p> <p> 便宜的光端機(jī)只有1個(gè)光接口1對(duì)設(shè)備，組成點(diǎn)到點(diǎn)工作方式也叫終端方式：TM </p> <p> 光口數(shù)量2：雙光口單方向 </p> <p> 較好的光端機(jī)有雙光口雙光口的光端機(jī)還分：1個(gè)還是2個(gè)光方向1個(gè)光方向的雙光口，是1+1備份工作的一旦主光纖斷了，輔光口保證工作。 </p> <p> 光口數(shù)量3：雙光口雙方向 </p> <p> 來(lái)自左光口的信號(hào)1部分落在本地，另1部分繼續(xù)從右光口發(fā)送，這種工作模式叫上下路模式：ADM具有ADM方式的光端機(jī)可以組成雙纖自愈環(huán) </p> <p> 雙纖自愈環(huán)的好處 </p> <p> 自愈環(huán)的好處就是，一旦光纜斷了，整個(gè)通信不會(huì)中斷。光纜正常時(shí)，各站間的信息從外環(huán)走端纜后，站1發(fā)向站2方向的信息，改由內(nèi)環(huán)走，當(dāng)光纜接好后，網(wǎng)絡(luò)自動(dòng)恢復(fù)正常只有具備ADM方式的光端機(jī)，才能實(shí)現(xiàn)自愈環(huán)。 </p> <p> 光口數(shù)量4：多光口多光方向 </p> <p> 比較好用的光端機(jī)是SDH，具有多個(gè)光方向但是價(jià)格就貴了很多在SDH設(shè)備中在詳細(xì)論述后面給出1個(gè)網(wǎng)絡(luò)圖，是各種方式的**。 </p> <p> 深圳騰云科創(chuàng)信息咨詢有限公司，擁有專業(yè)的技術(shù)團(tuán)隊(duì)，由
