（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)行管理和自動配置功能，優(yōu)化了網(wǎng)絡(luò)性能有，同時也使網(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(diǎn)來看，SDH屬于其比較低層的物理層，并未對其高層有嚴(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。將所有網(wǎng)元節(jié)點(diǎn)兩兩相連，就形成了網(wǎng)孔形網(wǎng)絡(luò)。四川代理光傳輸設(shè)備烽火ASON 780B</p><p

電力通信要求確保電能的生產(chǎn)、輸送、分配、消費(fèi)在瞬間是同時完成的。為了保證電網(wǎng)安全、經(jīng)濟(jì)地運(yùn)行, 必須配置調(diào)度、保護(hù)、遠(yuǎn)程控制等系統(tǒng)。這些系統(tǒng)的所有信息傳輸都必須由通信系統(tǒng)提供通道。由此可見, 通信在電力系統(tǒng)中的作用是非常關(guān)鍵的。隨著經(jīng)濟(jì)的發(fā)展, 電力系統(tǒng)容量急劇增加, 隨之而來的是輸電超高壓化, 接入業(yè)務(wù)多樣化。 </p> <p> 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(kuò)大范圍, 造成大面積停電甚至系統(tǒng)瓦解,不但經(jīng)濟(jì)損失十分慘重, 而且會給社會造成嚴(yán)重影響。因此電力系統(tǒng)的通信要有非常高的可靠性。由于SDH技術(shù)具有特有的優(yōu)勢, 采用SDH技術(shù)組網(wǎng)不但適合現(xiàn)代通信發(fā)展的需要,而且特別適合電力系統(tǒng)通信的需要。SDH網(wǎng)是由不同類型的SDH網(wǎng)元設(shè)備, 如終端復(fù)用設(shè)備(TM )、再生器(REG)、分插復(fù)用設(shè)備(ADM )、數(shù)字交叉連接(DXC) 設(shè)備等, 通過光纜互連而成的, 由這些網(wǎng)元設(shè)備完成SDH 網(wǎng)的上下業(yè)務(wù)、交叉連接業(yè)務(wù)、網(wǎng)絡(luò)故障自愈等傳送功能。SDH網(wǎng)的網(wǎng)絡(luò)節(jié)點(diǎn)(網(wǎng)元) 和傳輸線路的幾何排列就構(gòu)成了網(wǎng)絡(luò)的拓?fù)浣Y(jié)構(gòu)。網(wǎng)絡(luò)的基本拓?fù)浣Y(jié)構(gòu)大致有這樣幾種方式: 鏈形、星形、樹形、環(huán)形和網(wǎng)格形等。西藏光傳輸設(shè)備烽火IBAS 180</p><p
