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(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，也有專門為數(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(hù)、FEC 等），把SDH/SONET 的可運(yùn)營可管理能力應(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> <p> <br />

SDH傳輸體制是由PDH傳輸體制進(jìn)化而來的，因此它具有PDH體制所無可比擬的優(yōu)點(diǎn)，它是不同于PDH體制的全新的一代傳輸體制，與PDH相比在技術(shù)體制上進(jìn)行了根本的變革。 </p> <p> ◆SDH概念的**是從統(tǒng)一的國家電信網(wǎng)和國際互通的高度來組建數(shù)字通信網(wǎng)，是構(gòu)成綜合業(yè)務(wù)數(shù)字網(wǎng)（ISDN），特別是寬帶綜合業(yè)務(wù)數(shù)字網(wǎng)（B-ISDN）的重要組成部分。因?yàn)榕c傳統(tǒng)的PDH體制不同，按SDH組建的網(wǎng)絡(luò)是一個(gè)高度統(tǒng)一的、標(biāo)準(zhǔn)化的、智能化的網(wǎng)絡(luò)。它采用全球統(tǒng)一的接口以實(shí)現(xiàn)設(shè)備多廠家環(huán)境的兼容，在全程全網(wǎng)范圍實(shí)現(xiàn)高效的協(xié)調(diào)一致的管理和操作，實(shí)現(xiàn)靈活的組網(wǎng)與業(yè)務(wù)調(diào)度，實(shí)現(xiàn)網(wǎng)絡(luò)自愈功能，提高網(wǎng)絡(luò)資源利用率。并且由于維護(hù)功能的加強(qiáng)**降低了設(shè)備的運(yùn)行維護(hù)費(fèi)用。專業(yè)銷售SDH光傳輸設(shè)備，PTN設(shè)備，OTN設(shè)備。推薦深圳市騰云科創(chuàng)信息咨詢有限公司
