在各種寬帶光纖接入網(wǎng)技術(shù)中，采用SDH技術(shù)的接入網(wǎng)系統(tǒng)是應(yīng)用**普遍的。SDH的誕生解決了由于入戶媒質(zhì)的帶寬限制而跟不上骨干網(wǎng)和用戶業(yè)務(wù)需求的發(fā)展,而產(chǎn)生了用戶與**網(wǎng)之間的接入"瓶頸"的問題，同時提高了傳輸網(wǎng)上大量帶寬的利用率。SDH技術(shù)自從90年代引入以來，至今已經(jīng)是一種成熟、標(biāo)準(zhǔn)的技術(shù)，在骨干網(wǎng)中被***采用，且價格越來越低，在接入網(wǎng)中應(yīng)用可以將SDH技術(shù)在**網(wǎng)中的巨大帶寬優(yōu)勢和技術(shù)優(yōu)勢帶入接入網(wǎng)領(lǐng)域，充分利用SDH同步復(fù)用、標(biāo)準(zhǔn)化的光接口、強大的網(wǎng)管能力、靈活網(wǎng)絡(luò)拓撲能力和高可靠性帶來好處，在接入網(wǎng)的建設(shè)發(fā)展中長期受益。 </p> <p> <br /> </p><p style="text-indent:25px">根據(jù)電力通信點多面廣, 可靠性要求高的特點, 主干傳輸網(wǎng)可采用光纖自愈環(huán)的網(wǎng)絡(luò)拓撲結(jié)構(gòu), 也可以采用雙環(huán)相切、多環(huán)相切的主干網(wǎng)絡(luò)拓撲結(jié)構(gòu), 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(shè)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(jié)構(gòu)。另外, 采用SDH 設(shè)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。所謂自愈就是指在網(wǎng)絡(luò)發(fā)生故障(例如光纖斷裂)時, 無需人為干預(yù), 網(wǎng)絡(luò)能在極短的時間內(nèi)( ITU 2T規(guī)定為50ms 以內(nèi)) 自動恢復(fù)傳輸, 使用戶幾乎感覺不到網(wǎng)絡(luò)出了故障。傳統(tǒng)的組網(wǎng)概念中, 提高傳輸設(shè)備利用率是**關(guān)鍵的, 為了增加線路的占空系數(shù), 在每個節(jié)點都建立了許多直接通道, 致使網(wǎng)絡(luò)結(jié)構(gòu)非常復(fù)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(luò)結(jié)構(gòu), 實現(xiàn)強大的OAM功能, 降低傳輸費用并支持新業(yè)務(wù)的發(fā)展, 這正符合了現(xiàn)代通信發(fā)展的目標(biāo)。電力系統(tǒng)一旦發(fā)生故障, 如果通信不暢, 不能及時調(diào)度指揮,就會擴大***范圍。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
