SDH技術的誕生有其必然性，隨著通信的發(fā)展，要求傳送的信息不*是話音，還有文字、數(shù)據(jù)、圖像，和視頻等。加之數(shù)字通信和計算機技術的發(fā)展，在70至80年代，陸續(xù)出現(xiàn)了T1(DS1)／E1載波系統(tǒng)(1.544／2.048Mbps)、X.25幀中繼、ISDN(綜合業(yè)務數(shù)字網(wǎng)) 和FDDI(光纖分布式數(shù)據(jù)接口)等多種網(wǎng)絡技術。隨著信息社會的到來，人們希望現(xiàn)代信息傳輸網(wǎng)絡能快速、經(jīng)濟、有效地提供各種電路和業(yè)務，而上述網(wǎng)絡技術由于其業(yè)務的單調性，擴展的復雜性，帶寬的局限性，*在原有框架內修改或完善已無濟于事。SDH就是在這種背景下發(fā)展起來的。 </p><p> 電力通信**網(wǎng)的特點 </p> <p> 隨著網(wǎng)絡傳輸技術的不斷發(fā)展, 電力系統(tǒng)中基于寬帶數(shù)據(jù)網(wǎng)的應用也越來越多, 如圖像監(jiān)控、實時數(shù)據(jù)采集、實時控制、各種管理信息系統(tǒng)(MIS) 等,原先采用窄帶數(shù)據(jù)網(wǎng)承載的業(yè)務也逐步轉移到寬帶數(shù)據(jù)網(wǎng)上。除此之外, 電力通信**網(wǎng)本身還具有一些特點: </p> <p> (1) 電力通信網(wǎng)基本上應以光纖通信為主, 以微波通信作備份或補充。 </p> <p> (2) 光纖網(wǎng)絡拓撲結構復雜, 整個網(wǎng)絡節(jié)點數(shù)非常多, 需要傳輸設備有很強的組網(wǎng)和網(wǎng)絡管理能力,且對設備的可靠性要求非常高。 </p> <p> (3) 電力系統(tǒng)所敷設光纜通常芯數(shù)較少, 考慮到今后可能作為電信運營商, 應盡量節(jié)約光纖通信系統(tǒng)所占用的光纖芯數(shù)。 </p> <p> (4) 為滿足整個電力部門目前和將來的所有通信需求, 需要做到話音、視頻和數(shù)據(jù)多網(wǎng)融合。 </p> <p> （5) 目前的業(yè)務接口需求主要有POTS、2W/4W、E&M、V.24、V.35、ISDN、E1、E3/T 3、10Mb/100Mb以太網(wǎng)接口等, 未來的業(yè)務需求大,多基于寬帶數(shù)據(jù)網(wǎng)。采用基于SDH 和MSTP, 可使調度網(wǎng)實現(xiàn)計算機網(wǎng)絡的遠程互聯(lián), 在SDH平臺上實現(xiàn)以太網(wǎng)業(yè)務傳送功能, 從而實現(xiàn)二網(wǎng)合一, 且極大地降低網(wǎng)絡建設成本。從OSI模型的觀點來看，SDH屬于其比較低層的物理層。</p><div style="width:100%;text-align: center;"><img

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，這種方式可廉價地在一個業(yè)務提供點（POP）上提供高質量專線、ATM 、IP 等業(yè)務的接入、傳送和保護。 </p> <p> 隨著骨干傳輸容量不斷增大，城域傳輸網(wǎng)絡的接入能力也多樣化。但以IP為主的網(wǎng)絡業(yè)務仍然是不可預知的，這需要傳輸網(wǎng)絡具有更好的自適應能力，而這種自適應能力不**是網(wǎng)絡接口或網(wǎng)絡容量的適應能力，而且要求網(wǎng)絡連接的自適應能力?？偟膩碚f，低成本、靈活快速的完成運營商端局到用戶端的業(yè)務接入和業(yè)務收斂是對未來城域網(wǎng)接入系統(tǒng)的主要需求。
