（1）由于SDH有多種網(wǎng)絡拓撲結(jié)構(gòu)，它所組成的網(wǎng)絡非常靈活，它能增強網(wǎng)監(jiān)，運行管理和自動配置功能，優(yōu)化了網(wǎng)絡性能，同時也使網(wǎng)絡運行靈活、安全、可靠，使網(wǎng)絡的功能非常齊全和多樣化； </p> <p> （2）SDH有傳輸和交換的性能，它的系列設備的構(gòu)成能通過功能塊的自由組合，實現(xiàn)了不同層次和各種拓撲結(jié)構(gòu)的網(wǎng)絡，十分靈活； </p> <p> （3）SDH并不專屬于某種傳輸介質(zhì)，它可用于雙絞線、同軸電纜，但SDH用于傳輸高數(shù)據(jù)率則需用光纖。這一特點表明，SDH既適合用作干線通道，也可作支線通道。例如，我國的國家與省級有線電視干線網(wǎng)就是采用SDH，而且它也便于與光纖電纜混合網(wǎng)(HFC)相兼容。 </p> <p> （4）從OSI模型的觀點來看，SDH屬于其比較低層的物理層，并未對其高層有嚴格的限制，便于在SDH上采用各種網(wǎng)絡技術(shù)，支持ATM或IP傳輸； </p> <p> （5）SDH是嚴格同步的，從而保證了整個網(wǎng)絡穩(wěn)定可靠，誤碼少，且便于復用和調(diào)整； </p> <p> （6）標準的開放型光接口可以在基本光纜段上實現(xiàn)橫向兼容，降低了聯(lián)網(wǎng)成本。 </p> <p> <br /> </p> <p> <br /> </p><p> 同步數(shù)字系列（Synchronous Digital Hierarchy，縮寫為SDH）是一種將復接、線路傳輸及交換功能融為一體、并由統(tǒng)一網(wǎng)管系統(tǒng)操作的綜合信息傳送網(wǎng)絡，是美國貝爾通信技術(shù)研究所提出來的同步光網(wǎng)絡（SONET）。國際電話電報咨詢**會（CCITT）（現(xiàn)ITU-T）于1988年接受了SONET 概念并重新命名為SDH，這使其成為不*適用于光纖也適用于微波和衛(wèi)星傳輸?shù)耐ㄓ眉夹g(shù)體制。它可實現(xiàn)網(wǎng)絡有效管理、實時業(yè)務監(jiān)控、動態(tài)網(wǎng)絡維護、不同廠商設備間的互通等多項功能，能**提高網(wǎng)絡資源利用率、降低管理及維護費用、實現(xiàn)靈活可靠和***的網(wǎng)絡運行與維護。 </p>

近些年，點播電視、多媒體業(yè)務和其他寬帶業(yè)務如雨后春筍般紛紛出現(xiàn)，為SDH應用在接入網(wǎng)中提供了廣闊的空間。SDH技術(shù)應用于接入網(wǎng)的好處是：1）對于要求高可靠、高質(zhì)量業(yè)務的大型企事業(yè)用戶，SDH可以提供較為理想的網(wǎng)絡性能和業(yè)務可靠性。2）可以將網(wǎng)管范圍擴展至用戶端，簡化維護工作。3）利用SDH固有靈活性，可使網(wǎng)絡運營者更快、更有效地提供用戶所需的長期和短期業(yè)務需求。
