SDH作為新一代理想的傳輸體系，具有路由自動(dòng)選擇能力，上下電路方便，維護(hù)、控制、管理功能強(qiáng)，標(biāo)準(zhǔn)統(tǒng)一，便于傳輸更高速率的業(yè)務(wù)等優(yōu)點(diǎn)，能很好地適應(yīng)通信網(wǎng)飛速發(fā)展的需要。迄今，SDH得到了空前的應(yīng)用與發(fā)展。在標(biāo)準(zhǔn)化方面，已建立和即將建立的一系列建議已基本上覆蓋了SDH的方方面面。在干線網(wǎng)和長(zhǎng)途網(wǎng)、中繼網(wǎng)、接入網(wǎng)中它開(kāi)始廣泛應(yīng)用。且在光纖通信、微波通信、衛(wèi)星通信中也積極地開(kāi)展研究與應(yīng)用。

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。
