DWDM與OTN的區(qū)別：OTN即光傳送網(wǎng)，實(shí)際上是DWDM（密集型光波復(fù)用）和ASON（自動(dòng)光交換網(wǎng)絡(luò)）的綜合體。首先OTN具備光交叉能力，即通過(guò)加載WSS型ROADM模塊，可以使其組成類(lèi)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(gè)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(zhuān)門(mén)為數(shù)據(jù)業(yè)務(wù)服務(wù)的ODU1E和ODU2E。 </p> <p> ◆光傳送網(wǎng)OTN是由ITU-T G.872、G.798、G.709等建議定義的一種全新的光傳送技術(shù)體制，它包括光層和電層的完整體系結(jié)構(gòu)，對(duì)于各層網(wǎng)絡(luò)都有相應(yīng)的管理監(jiān)控機(jī)制和網(wǎng)絡(luò)生存性機(jī)制。OTN 的思想來(lái)源于SDH/SONET技術(shù)體制（例如映射、復(fù)用、交叉連接、嵌入式開(kāi)銷(xiāo)、保護(hù)、FEC 等），把SDH/SONET 的可運(yùn)營(yíng)可管理能力應(yīng)用到WDM 系統(tǒng)中，同時(shí)具備了SDH/SONET靈活可靠和WDM 容量大的優(yōu)勢(shì)。 </p> <p> <br /> </p>
