光纖接口是用來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標準化，使用由國際性的接插件標準定義的8個位置（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年由美國電子工業(yè)協(xié)會聯(lián)合貝爾系統(tǒng)、調(diào)制解調(diào)器廠家及計算機終端生產(chǎn)廠家共同制定的用于串行通訊的標準。它的全名是“數(shù)據(jù)終端設(shè)備和數(shù)據(jù)通訊設(shè)備之間串行二進制數(shù)據(jù)交換接口技術(shù)標準”。該標準規(guī)定采用一個25個腳的DB25連接器，對連接器的每個引腳的信號內(nèi)容加以規(guī)定，還對各種信號的電平加以規(guī)定，新疆光傳輸設(shè)備華為STM-16。（多用DB9），新疆光傳輸設(shè)備華為STM-16。RJ-11接口就是我們平時所說的電話線接口 </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，新疆光傳輸設(shè)備華為STM-16。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”，觸點或者打線針。 </p> <p> <br />

由于SDH有多種網(wǎng)絡(luò)拓撲結(jié)構(gòu)，它所組成的網(wǎng)絡(luò)非常靈活，它能增強網(wǎng)監(jiān)，運行管理和自動配置功能，優(yōu)化了網(wǎng)絡(luò)性能，同時也使網(wǎng)絡(luò)運行靈活、安全、可靠，使網(wǎng)絡(luò)的功能非常齊全和多樣化； </p> <p> SDH有傳輸和交換的性能，它的系列設(shè)備的構(gòu)成能通過功能塊的自由組合，實現(xiàn)了不同層次和各種拓撲結(jié)構(gòu)的網(wǎng)絡(luò)，十分靈活； </p> <p> SDH并不專屬于某種傳輸介質(zhì)，它可用于雙絞線、同軸電纜，但SDH用于傳輸高數(shù)據(jù)率則需用光纖。這一特點表明，SDH既適合用作干線通道，也可作支線通道。例如，我國的國家與省級有線電視干線網(wǎng)就是采用SDH，而且它也便于與光纖電纜混合網(wǎng)（HFC）相兼容。 </p> <p> 從OSI模型的觀點來看，SDH屬于其比較低層的物理層，并未對其高層有嚴格的限制，便于在SDH上采用各種網(wǎng)絡(luò)技術(shù)，支持ATM或IP傳輸； </p> <p> SDH是嚴格同步的，從而保證了整個網(wǎng)絡(luò)穩(wěn)定可靠，誤碼少，且便于復用和調(diào)整； </p> <p> 標準的開放型光接口可以在基本光纜段上實現(xiàn)橫向兼容，降低了聯(lián)網(wǎng)成本。 </p> <p> <br /> </p><p>

SDH體制是新體制，剛剛誕生10年，**小容量的SDH是155Mb/s叫STM-1有63個E1。4個STM-1復接成1個STM-4，也叫622,4個STM-4復接成1個STM-16，叫2.5G,4個STM-16復接成1個STM-64，叫10G </p> <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勤務電話,用于站間聯(lián)絡(luò),實際上很少使用很便宜的光端機沒有勤務電話,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)，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,就是交叉連接方式。 </p> <p> <br />

光傳輸設(shè)備的***使用，因此，隨時都有報警的發(fā)生，正確掌握各種報警的含義和特征有利于故障的定位和解決。因為，系統(tǒng)故障時，網(wǎng)管都會記錄各種報警，包括發(fā)生的時間、位置以及其他設(shè)備的表現(xiàn)，根據(jù)這些特征結(jié)合開銷字節(jié)和警告原理機制，對故障的排除十分有用。怎樣才能更好的使用報警分析法，關(guān)鍵是及時準確獲取報警信息。因此，有必要了解故障的來源，故障的來源一方面是網(wǎng)管的記錄，這個來源非常容易也比較詳實，而且可以前后對比，通盤考慮，方便故障的排除；另一方面是觀察和記錄設(shè)備的指示燈。雖然這種方法具有時效性，但是比較片面，不能反映設(shè)備過去情況，不夠***。因此在運用報警分析法時一定要綜合考慮。新疆光傳輸設(shè)備華為STM-16</p><p
