隨著網(wǎng)絡(luò)傳輸技術(shù)的不斷發(fā)展, 電力系統(tǒng)中基于寬帶數(shù)據(jù)網(wǎng)的應(yīng)用也越來(lái)越多, 如圖像監(jiān)控、實(shí)時(shí)數(shù)據(jù)采集、實(shí)時(shí)控制、各種管理信息系統(tǒng)(MIS) 等,原先采用窄帶數(shù)據(jù)網(wǎng)承載的業(yè)務(wù)也逐步轉(zhuǎn)移到寬帶數(shù)據(jù)網(wǎng)上。除此之外, 電力通信**網(wǎng)本身還具有一些特點(diǎn): </p> <p> (1) 電力通信網(wǎng)基本上應(yīng)以光纖通信為主, 以微波通信作備份或補(bǔ)充。 </p> <p> (2) 光纖網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)復(fù)雜, 整個(gè)網(wǎng)絡(luò)節(jié)點(diǎn)數(shù)非常多, 需要傳輸設(shè)備有很強(qiáng)的組網(wǎng)和網(wǎng)絡(luò)管理能力,且對(duì)設(shè)備的可靠性要求非常高。 </p> <p> (3) 電力系統(tǒng)所敷設(shè)光纜通常芯數(shù)較少, 考慮到今后可能作為電信運(yùn)營(yíng)商, 應(yīng)盡量節(jié)約光纖通信系統(tǒng)所占用的光纖芯數(shù)。 </p> <p> (4) 為滿(mǎn)足整個(gè)電力部門(mén)目前和將來(lái)的所有通信需求, 需要做到話音、視頻和數(shù)據(jù)多網(wǎng)融合。 </p> <p>

SDH傳輸網(wǎng)是由不同類(lèi)型的網(wǎng)元通過(guò)光纜線路的連接組成的，通過(guò)不同的網(wǎng)元完成SDH網(wǎng)的傳送功能：上/下業(yè)務(wù)、交叉連接業(yè)務(wù)、網(wǎng)絡(luò)故障自愈等。下面我們講述SDH網(wǎng)中常見(jiàn)網(wǎng)元的特點(diǎn)和基本功能。 </p> <p> TM——終端復(fù)用器 </p> <p> 終端復(fù)用器用在網(wǎng)絡(luò)的終端站點(diǎn)上，例如一條鏈的兩個(gè)端點(diǎn)上，它是一個(gè)雙端口器件。它的作用是將支路端口的低速信號(hào)復(fù)用到線路端口的高速信號(hào)STM-N中，或從STM-N的信號(hào)中分出低速支路信號(hào)。請(qǐng)注意它的線路端口輸入/輸出一路STM-N信號(hào)，而支路端口卻可以輸出/輸入多路低速支路信號(hào)。在將低速支路信號(hào)復(fù)用進(jìn)STM-N幀（將低速信號(hào)復(fù)用到線路）上時(shí)，有一個(gè)交叉的功能，例如：可將支路的一個(gè)STM-1信號(hào)復(fù)用進(jìn)線路上的STM-16信號(hào)中的任意位置上，也就是指復(fù)用在1~16個(gè)STM-1的任一個(gè)位置上。將支路的2Mbit/s信號(hào)可復(fù)用到一個(gè)STM-1中63個(gè)VC12的任一個(gè)位置上去。對(duì)于華為設(shè)備，TM的線路端口（光口）一般以西向端口默認(rèn)表示的。 </p><p> SDH的復(fù)用包括兩種情況： </p> <p> 1、由STM-1信號(hào)復(fù)用成STM-N信號(hào) </p> <p> 復(fù)用的方法主要通過(guò)字節(jié)間插的同步復(fù)用方式來(lái)完成的，復(fù)用的基數(shù)是4，即4×STM-1→STM-4，4×STM-4→STM-16。在復(fù)用過(guò)程中保持幀頻不變（8000幀/秒），這就意味著高一級(jí)的STM-N信號(hào)是低一級(jí)的STM-n信號(hào)速率的4倍。 </p> <p> 在進(jìn)行字節(jié)間插復(fù)用過(guò)程中，各幀的信息凈負(fù)荷和指針字節(jié)按原值進(jìn)行字節(jié)間插復(fù)用，而STM-N的段開(kāi)銷(xiāo)并不是由所有低階STM-N幀中的段開(kāi)銷(xiāo)間插復(fù)用而成，而是舍棄了某些低階幀中的段開(kāi)銷(xiāo)。 </p> <p> 2、由PDH支路信號(hào)復(fù)用成STM-N信號(hào) </p> <p> 各種PDH支路信號(hào)復(fù)用進(jìn)STM-N幀的過(guò)程都要經(jīng)歷映射、定位、復(fù)用三個(gè)步驟。映射相當(dāng)于信號(hào)打包，定位伴隨與指針調(diào)整，復(fù)用相當(dāng)于字節(jié)間插復(fù)用。ITU-T規(guī)定了一整套完整的映射復(fù)用結(jié)構(gòu)，也就是映射復(fù)用路線，通過(guò)這些路線可將PDH的3個(gè)系列的數(shù)字信號(hào)以多種方法復(fù)用成STM-N信號(hào)。 </p> <p> 復(fù)用結(jié)構(gòu)包括了一些基本的復(fù)用單元：C－容器、VC－虛容器、TU－支路單元、TUG－支路單元組、AU－管理單元、AUG－管理單元組，這些復(fù)用單元的下標(biāo)表示與此復(fù)用單元相應(yīng)的信號(hào)級(jí)別。 </p> <p> 從一個(gè)有效負(fù)荷到STM-N的復(fù)用路線不是***的，有多條路線（也就是說(shuō)有多種復(fù)用方法），8Mbit/s的PDH支路信號(hào)是無(wú)法復(fù)用成STM-N信號(hào)的。 </p> <p> <br /> 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><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="陜西全新光傳輸設(shè)備烽火 E1板卡,烽火"
