近些年，點(diǎn)播電視、多媒體業(yè)務(wù)和其他寬帶業(yè)務(wù)如雨后春筍般紛紛出現(xiàn)，為SDH應(yīng)用在接入網(wǎng)中提供了廣闊的空間。SDH技術(shù)應(yīng)用于接入網(wǎng)的好處是：1）對(duì)于要求高可靠、高質(zhì)量業(yè)務(wù)的大型企事業(yè)用戶，SDH可以提供較為理想的網(wǎng)絡(luò)性能和業(yè)務(wù)可靠性。2）可以將網(wǎng)管范圍擴(kuò)展至用戶端，簡(jiǎn)化維護(hù)工作。3）利用SDH固有靈活性，可使網(wǎng)絡(luò)運(yùn)營(yíng)者更快、更有效地提供用戶所需的長(zhǎng)期和短期業(yè)務(wù)需求。 </p> <p> 從技術(shù)上來(lái)看，接入層的相對(duì)帶寬需求較小，需要提供IP、TDM，可能還有ATM等綜合業(yè)務(wù)傳送。以SDH 系統(tǒng)為基礎(chǔ)并能夠提供IP 、ATM 傳送與處理的系統(tǒng)（包括TDM、IP與ATM接口，甚至包括IP 和ATM 交換模塊）將是解決接入層傳送的主要方法，這種方式可廉價(jià)地在一個(gè)業(yè)務(wù)提供點(diǎn)（POP）上提供高質(zhì)量專(zhuān)線、ATM 、IP 等業(yè)務(wù)的接入、傳送和保護(hù)。 </p> </p> <p> <br /> </p> <p> <br /> </p><p> SDH網(wǎng)絡(luò)的常見(jiàn)網(wǎng)元和功能 </p> <p> REG——再生中繼器 </p> <p> 光傳輸網(wǎng)的再生中繼器有兩種，一種是純光的再生中繼器，主要進(jìn)行光功率放大以延長(zhǎng)光傳輸距離；另一種是用于脈沖再生整形的電再生中繼器，主要通過(guò)光/電變換、電信號(hào)抽樣、判決、再生整形、電/光變換，以達(dá)到不積累線路噪聲，保證線路上傳送信號(hào)波形的完好性。此處講的是后一種再生中繼器，REG是雙端口器件，只有兩個(gè)線路端口——W、E。 </p> <p> 它的作用是將w/e側(cè)的光信號(hào)經(jīng)O/E、抽樣、判決、再生整形、E/O在e或w側(cè)發(fā)出。注意到?jīng)]有，REG與ADM相比*少了支路端口，所以ADM若本地不上/下話路（支路不上/下信號(hào)）時(shí)完全可以等效一個(gè)REG。 </p> <p> 真正的REG只需處理STM-N幀中的RSOH，且不需要交叉連接功能（w—e直通即可），而ADM和TM因?yàn)橐瓿蓪⒌退僦沸盘?hào)分/插到STM-N中，所以不*要處理RSOH，而且還要處理MSOH；另外ADM和TM都具有交叉復(fù)用能力（有交叉連接功能），因此用ADM來(lái)等效REG有點(diǎn)大材小用了。電力網(wǎng)的發(fā)展對(duì)電力系統(tǒng)**通信網(wǎng)提出了更高的要求。</p><div

分/插復(fù)用器用于SDH傳輸網(wǎng)絡(luò)的轉(zhuǎn)接站點(diǎn)處，例如鏈的中間結(jié)點(diǎn)或環(huán)上結(jié)點(diǎn)，是SDH網(wǎng)上使用**多、**重要的一種網(wǎng)元，它是一個(gè)三端口的器件。 </p> <p> ADM有兩個(gè)線路端口和一個(gè)支路端口。兩個(gè)線路端口各接一側(cè)的光纜（每側(cè)收/發(fā)共兩根光纖），為了描述方便我們將其分為西（W）向、東向（E）兩個(gè)線路端口。ADM的作用是將低速支路信號(hào)交叉復(fù)用進(jìn)東或西向線路上去，或從東或西側(cè)線路端口收的線路信號(hào)中拆分出低速支路信號(hào)。另外，還可將東/西向線路側(cè)的STM-N信號(hào)進(jìn)行交叉連接，例如將東向STM-16中的3#STM-1與西向STM-16中的15#STM-1相連接。 </p> <p> ADM是SDH**重要的一種網(wǎng)元，通過(guò)它可等效成其它網(wǎng)元，即能完成其它網(wǎng)元的功能，例如：一個(gè)ADM可等效成兩個(gè)TM。為了實(shí)時(shí)監(jiān)測(cè)貨物（打包的低速信號(hào)）在傳輸過(guò)程中是否有損壞。寧夏光端機(jī)烽火 E1板卡</p><p
