二纖雙向復用段保護環(huán)將每根光纖的前一半時隙傳送主用業(yè)務(wù)，后一半時隙傳送額外業(yè)務(wù)，也就是說一根光纖的保護時隙用來保護另一根光纖上的主用業(yè)務(wù)。業(yè)務(wù)容量為四纖雙向復用段保護環(huán)的1/2，即M/2（STM-N），其中M是節(jié)點數(shù)。它在組網(wǎng)中使用得較多，海南全新光傳輸設(shè)備烽火ASON

單向通道保護環(huán)的比較大業(yè)務(wù)容量是STM-N，二纖雙向復用段保護環(huán)的業(yè)務(wù)容量為M/2 ×STM-N（M是環(huán)上節(jié)點數(shù)）。 </p> <p> 復雜性 </p> <p> 二纖單向通道保護環(huán)，無論從實現(xiàn)控制的復雜性，還是設(shè)備的開發(fā)和制作難度來說，都是各種倒換環(huán)中**簡單的，海南全新光傳輸設(shè)備烽火ASON 780B。由于它不涉及APS的協(xié)議處理過程，海南全新光傳輸設(shè)備烽火ASON

SDH作為新一代理想的傳輸體系，具有路由自動選擇能力，上下電路方便，維護、控制、管理功能強，標準統(tǒng)一，便于傳輸更高速率的業(yè)務(wù)等優(yōu)點，能很好地適應(yīng)通信網(wǎng)飛速發(fā)展的需要。迄今，SDH得到了空前的應(yīng)用與發(fā)展。在標準化方面，已建立和即將建立的一系列建議已基本上覆蓋了SDH的方方面面。在干線網(wǎng)和長途網(wǎng)、中繼網(wǎng)、接入網(wǎng)中它開始廣泛應(yīng)用。且在光纖通信、微波通信、衛(wèi)星通信中也積極地開展研究與應(yīng)用。 </p> <p> <br /> </p><p> SDH網(wǎng)絡(luò)的常見網(wǎng)元和功能 </p> <p> 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(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(luò)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，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。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(shè)備，TM的線路端口（光口）一般以西向端口默認表示的。積極響應(yīng)配合客戶做好售后服務(wù)，在業(yè)界贏得廣大客戶認可及一致好評。努力奉獻，您的滿意是我們一直的追求。</p><div

分/插復用器用于SDH傳輸網(wǎng)絡(luò)的轉(zhuǎn)接站點處，例如鏈的中間結(jié)點或環(huán)上結(jié)點，是SDH網(wǎng)上使用**多、**重要的一種網(wǎng)元，它是一個三端口的器件。 </p> <p> ADM有兩個線路端口和一個支路端口。兩個線路端口各接一側(cè)的光纜（每側(cè)收/發(fā)共兩根光纖），為了描述方便我們將其分為西（W）向、東向（E）兩個線路端口。ADM的作用是將低速支路信號交叉復用進東或西向線路上去，或從東或西側(cè)線路端口收的線路信號中拆分出低速支路信號。另外，還可將東/西向線路側(cè)的STM-N信號進行交叉連接，例如將東向STM-16中的3#STM-1與西向STM-16中的15#STM-1相連接。 </p> <p> ADM是SDH**重要的一種網(wǎng)元，通過它可等效成其它網(wǎng)元，即能完成其它網(wǎng)元的功能，例如：一個ADM可等效成兩個TM。分/插復用器用于SDH傳輸網(wǎng)絡(luò)的轉(zhuǎn)接站點處。重慶SDH光端機烽火RET</p><p
