（1）由于SDH多種網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)，它所組成的網(wǎng)絡(luò)非常靈活，它能增強(qiáng)網(wǎng)監(jiān)，運(yùn)行管理和自動(dòng)配置功能，優(yōu)化了網(wǎng)絡(luò)性能有，同時(shí)也使網(wǎng)絡(luò)運(yùn)行靈活、安全、可靠，使網(wǎng)絡(luò)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(shè)備的構(gòu)成能通過(guò)功能塊的自由組合，實(shí)現(xiàn)了不同層次和各種拓?fù)浣Y(jié)構(gòu)的網(wǎng)絡(luò)，十分靈活； </p> <p> （3）SDH并不專(zhuān)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(diǎn)表明，SDH既適合用作干線通道，也可作支線通道。例如，我國(guó)的國(guó)家與省級(jí)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(diǎn)來(lái)看，SDH屬于其比較低層的物理層，并未對(duì)其高層有嚴(yán)格的限制，便于在SDH上采用各種網(wǎng)絡(luò)技術(shù)，支持ATM或IP傳輸； </p> <p> （5）SDH是嚴(yán)格同步的，從而保證了整個(gè)網(wǎng)絡(luò)穩(wěn)定可靠，誤碼少，且便于復(fù)用和調(diào)整； </p> <p> （6）標(biāo)準(zhǔn)的開(kāi)放型光接口 </p> <p> 可以在基本光纜段上實(shí)現(xiàn)橫向兼容，降低了聯(lián)網(wǎng)成本。貴州SDH光傳輸設(shè)備烽火2路交換式千兆以太網(wǎng)處理板由于采用了較先進(jìn)的分插復(fù)用器（ADM）、數(shù)字交叉連接（DXC）。</p><div
