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。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。</p><div

采用相切環(huán)時可在兩環(huán)相切的節(jié)點上采用雙環(huán)網(wǎng)元設備交叉保護, 克服雙環(huán)相切時節(jié)點保護可靠性差的問題。支路可根據(jù)實際需要采用鏈形、星形、樹形等結構。另外, 采用SDH 設備的光纖自愈環(huán)可實現(xiàn)多種形式的通道保護, 而且SDH 光纖環(huán)有較強的自愈能力。傳統(tǒng)的組網(wǎng)概念中,提高傳輸設備利用率是比較關鍵的,為了增加線路的占空比,在每個節(jié)點都建立了許多直接通道，致使網(wǎng)絡結構非常復雜。而利用SDH 組網(wǎng),使用SDH提供的豐富的開銷字節(jié),就可以極大簡化網(wǎng)絡結構,實現(xiàn)強大的OAM功能,降低傳輸費用并支持新業(yè)務的發(fā)展, 這正符合了現(xiàn)代通信發(fā)展的目標。同PDH相比, SDH組網(wǎng)的巨大的優(yōu)越性完全發(fā)揮出來了。樹形網(wǎng)絡拓撲可看成是鏈形拓撲和星形拓撲的結合。西藏SDH設備烽火8路帶交換功能快速以太網(wǎng)處理板</p><p

電力通信要求確保電能的生產(chǎn)、輸送、分配、消費在瞬間是同時完成的。為了保證電網(wǎng)安全、經(jīng)濟地運行, 必須配置調度、保護、遠程控制等系統(tǒng)。這些系統(tǒng)的所有信息傳輸都必須由通信系統(tǒng)提供通道。由此可見, 通信在電力系統(tǒng)中的作用是非常關鍵的。隨著經(jīng)濟的發(fā)展, 電力系統(tǒng)容量急劇增加, 隨之而來的是輸電超高壓化, 接入業(yè)務多樣化。 </p> <p> 電力系統(tǒng)一旦發(fā)生故障, 如果通信不暢, 不能及時調度指揮,就會擴大范圍, 造成大面積停電甚至系統(tǒng)瓦解,不但經(jīng)濟損失十分慘重, 而且會給社會造成嚴重影響。因此電力系統(tǒng)的通信要有非常高的可靠性。由于SDH技術具有特有的優(yōu)勢, 采用SDH技術組網(wǎng)不但適合現(xiàn)代通信發(fā)展的需要,而且特別適合電力系統(tǒng)通信的需要。SDH網(wǎng)是由不同類型的SDH網(wǎng)元設備, 如終端復用設備(TM )、再生器(REG)、分插復用設備(ADM )、數(shù)字交叉連接(DXC) 設備等, 通過光纜互連而成的, 由這些網(wǎng)元設備完成SDH
