設(shè)備的光纖自愈環(huán)可實(shí)現(xiàn)多種形式的通道保護(hù), 而且SDH 光纖環(huán)有較強(qiáng)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(shí), 無(wú)需人為干預(yù), 網(wǎng)絡(luò)能在極短的時(shí)間內(nèi)( ITU 2T規(guī)定為50ms

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(kāi)銷(xiāo)字節(jié), 就可以極大簡(jiǎn)化網(wǎng)絡(luò)結(jié)構(gòu), 實(shí)現(xiàn)強(qiáng)大的OAM功能, 降低傳輸費(fèi)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)。</p><p> SDH的應(yīng)用 </p> <p> 由于以上所述的SDH的眾多特性，使其在廣域網(wǎng)領(lǐng)域和**網(wǎng)領(lǐng)域得到了巨大的發(fā)展。中國(guó)移動(dòng)、電信、聯(lián)通、廣電等電信運(yùn)營(yíng)商都已經(jīng)大規(guī)模建設(shè)了基于SDH的骨干光傳輸網(wǎng)絡(luò)。利用大容量的SDH環(huán)路承載IP業(yè)務(wù)、ATM業(yè)務(wù)或直接以租用電路的方式出租給企、事業(yè)單位。而一些大型的**網(wǎng)絡(luò)也采用了SDH技術(shù)，架設(shè)系統(tǒng)內(nèi)部的SDH光環(huán)路，以承載各種業(yè)務(wù)。比如電力系統(tǒng)，就利用SDH環(huán)路承載內(nèi)部的數(shù)據(jù)、遠(yuǎn)控、視頻、語(yǔ)音等業(yè)務(wù)。 </p> <p> 而對(duì)于組網(wǎng)更加迫切、而又沒(méi)有可能架設(shè)**SDH環(huán)路的單位，很多都采用了租用電信運(yùn)營(yíng)商電路的方式。由于SDH基于物理層的特點(diǎn)，單位可在租用電路上承載各種業(yè)務(wù)而不受傳輸?shù)南拗?。承載方式有很多種，可以是利用基于TDM技術(shù)的綜合復(fù)用設(shè)備實(shí)現(xiàn)多業(yè)務(wù)的復(fù)用，也可以利用基于IP的設(shè)備實(shí)現(xiàn)多業(yè)務(wù)的分組交換。SDH技術(shù)可真正實(shí)現(xiàn)租用電路的帶寬保證，安全性方面也優(yōu)于VPN等方式。在****和對(duì)安全性非常注重的企業(yè)，SDH租用線路得到了***的應(yīng)用。一般來(lái)說(shuō)，SDH可提供E1、E3、STM-1或STM-4等接口，完全可以滿(mǎn)足各種帶寬要求。同時(shí)在價(jià)格方面，也已經(jīng)為大部分單位所接受。
