SDH傳輸網(wǎng)是由不同類型的網(wǎng)元通過光纜線路的連接組成的，通過不同的網(wǎng)元完成SDH網(wǎng)的傳送功能：上/下業(yè)務、交叉連接業(yè)務、網(wǎng)絡故障自愈等，湖南光端機烽火ASON 780B。下面我們講述SDH網(wǎng)中常見網(wǎng)元的特點和基本功能。 </p> <p> TM——終端復用器 </p> <p> 終端復用器用在網(wǎng)絡的終端站點上，例如一條鏈的兩個端點上，它是一個雙端口器件。它的作用是將支路端口的低速信號復用到線路端口的高速信號STM-N中，湖南光端機烽火ASON 780B，或從STM-N的信號中分出低速支路信號。請注意它的線路端口輸入/輸出一路STM-N信號，而支路端口卻可以輸出/輸入多路低速支路信號。在將低速支路信號復用進STM-N幀（將低速信號復用到線路）上時，有一個交叉的功能，例如：可將支路的一個STM-1信號復用進線路上的STM-16信號中的任意位置上，也就是指復用在1~16個STM-1的任一個位置上，湖南光端機烽火ASON 780B。將支路的2Mbit/s信號可復用到一個STM-1中63個VC12的任一個位置上去。對于華為設備，TM的線路端口（光口）一般以西向端口默認表示的。管理單元指針位于STM-N幀中第4行的***到第9×N列。湖南光端機烽火ASON 780B</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

保護倒換系統(tǒng)：目前環(huán)形網(wǎng)絡的拓撲結構用得比較多，因為環(huán)形網(wǎng)具有較強的自愈功能。自愈環(huán)的分類可按保護的業(yè)務級別、環(huán)上業(yè)務的方向、網(wǎng)元節(jié)點間光纖數(shù)來劃分。按環(huán)上業(yè)務的方向可將自愈環(huán)分為單向環(huán)和雙向環(huán)兩大類；按網(wǎng)元節(jié)點間的光纖數(shù)可將自愈環(huán)劃分為雙纖環(huán)(一對收／發(fā)光纖)和四纖環(huán)(兩對收發(fā)光纖)；按保護的業(yè)務級別可將自愈環(huán)劃分為通道保護環(huán)和復用段保護環(huán)兩大類。

SDH通信網(wǎng)具有保護機制實現(xiàn)網(wǎng)絡的自愈，在發(fā)生短暫失效時會自動切換到保護通道，而不需要人工切換。然而，由于人為因素或設備故障，一旦發(fā)生業(yè)務中斷，尤其是傳輸繼電保護信號的網(wǎng)絡發(fā)生故障，造成的巨大損失無法估計。SDH設備的保護方式應符合ITU.T建議G．841規(guī)范及將來的<span>相關</span>建議要求。例如某地環(huán)采用二纖雙向復用段保護方式，當線路出現(xiàn)故障時可通過傳輸系統(tǒng)的保護倒換機制，使業(yè)務迅速恢復(保護倒換時間在50rIls以內)。在二纖雙向復用段保護環(huán)上無專門的主、備用光纖，每一條光纖的前半個時隙是主用信道，后半個時隙是備信道，兩根光纖上業(yè)務流向相反。

<span style="font-size:16px;font-family:"Microsoft YaHei";">（1）由于SDH有多種網(wǎng)絡拓撲結構，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；</span> </p> <p> <span style="font-size:16px;font-family:"Microsoft YaHei";">（2）SDH有傳輸和交換的性能，它的系列設備的構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構的網(wǎng)絡，十分靈活；</span> </p> <p> <span style="font-size:16px;font-family:"Microsoft YaHei";">（3）SDH并不專屬于某種傳輸介質，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。</span> </p> <p> <span style="font-size:16px;font-family:"Microsoft YaHei";">（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，支持ATM或IP傳輸；</span> </p> <p> <span style="font-size:16px;font-family:"Microsoft YaHei";">（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，且便于復用和調整；</span> </p> <p> <span style="font-size:16px;font-family:"Microsoft YaHei";">（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。</span> 例如一條鏈的兩個端點上，它是一個雙端口器件。寧夏銷售光傳輸設備烽火 E1板卡</p><p style="text-indent:25px">。隨著經(jīng)濟的發(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)務多樣化。湖南光端機烽火ASON 780B</p><p> SDH的主要設備 </p> <p>
