/> </p> <p> （1）SDH傳輸系統(tǒng)在國際上有統(tǒng)一的幀結(jié)構(gòu)，數(shù)字傳輸標準速率和標準的光路接口，使網(wǎng)管系統(tǒng)互通，因此有很好的橫向兼容性，它能與現(xiàn)有的PDH完全兼容，并容納各種新的業(yè)務(wù)信號，形成了全球統(tǒng)一的數(shù)字傳輸體制標準，提高了網(wǎng)絡(luò)的可靠性； </p> <p> <br /> </p> <p> （2）SDH接入系統(tǒng)的不同等級的碼流在幀結(jié)構(gòu)凈負荷區(qū)內(nèi)的排列非常有規(guī)律，而凈負荷與網(wǎng)絡(luò)是同步的，它利用軟件能將高速信號一次直接分插出低速支路信號，實現(xiàn)了一次復(fù)用的特性，克服了PDH準同步復(fù)用方式對全部高速信號進行逐級分解然后再生復(fù)用的過程，由于大的簡化了DXC，減少了背靠背的接口復(fù)用設(shè)備，改善了網(wǎng)絡(luò)的業(yè)務(wù)傳送透明性； </p> <p> <br /> </p> <p> （3）由于采用了較先進的分插復(fù)用器（ADM）、數(shù)字交叉連接（DXC）、網(wǎng)絡(luò)的自愈功能和重組功能就顯得非常強大，具有較強的生存率。因SDH幀結(jié)構(gòu)中安排了信號的5％開銷比特，它的網(wǎng)管功能顯得特別強大，并能統(tǒng)一形成網(wǎng)絡(luò)管理系統(tǒng)，為網(wǎng)絡(luò)的自動化、智能化、信道的利用率以及降低網(wǎng)絡(luò)的維管費和生存能力起到了積極作用；中興SDH光傳輸設(shè)備，光端機。認準深圳市騰云科創(chuàng)信息咨詢有限公司

DWDM與OTN的區(qū)別：OTN即光傳送網(wǎng)，實際上是DWDM（密集型光波復(fù)用）和ASON（自動光交換網(wǎng)絡(luò)）的綜合體。首先OTN具備光交叉能力，即通過加載WSS型ROADM模塊，可以使其組成類似于ASON設(shè)備的MESH網(wǎng)結(jié)構(gòu)，即提高業(yè)務(wù)調(diào)度的靈活性，又增加了網(wǎng)絡(luò)安全性；其次OTN具備電交叉能力，即每個波道的子速率交叉能力，這一部分與SDH的作用非常相像，但OTN有自己特殊的幀結(jié)構(gòu)，那就是2.5G顆粒的ODU1和10G顆粒的ODU2，也有專門為數(shù)據(jù)業(yè)務(wù)服務(wù)的ODU1E和ODU2E。

的思想來源于SDH/SONET技術(shù)體制（例如映射、復(fù)用、交叉連接、嵌入式開銷、保護、FEC 等），把SDH/SONET 的可運營可管理能力應(yīng)用到WDM 系統(tǒng)中，同時具備了SDH/SONET靈活可靠和WDM 容量大的優(yōu)勢。 </p> <p> </p> <p> <br /> </p> <p> <br /> </p> <p> <br />
