class="title">詳細(xì)說明</p><div id="eyfripb" class="box"><p><p> 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，湖北SDH光端機(jī)中興IBAS 180、G.798，湖北SDH光端機(jī)中興IBAS 180、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)，湖北SDH光端機(jī)中興IBAS 180，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(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> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

SDH的眾多特性，使其在廣域網(wǎng)領(lǐng)域和**網(wǎng)領(lǐng)域得到了巨大的發(fā)展。中國(guó)移動(dòng)、電信、聯(lián)通、廣電等電信運(yùn)營(yíng)商都已經(jīng)大規(guī)模建設(shè)了基于SDH的骨干光傳輸網(wǎng)絡(luò)。利用大容量的SDH環(huán)路承載IP業(yè)務(wù)、ATM業(yè)務(wù)或直接以租用電路的方式出租給企、事業(yè)單位。而一些大型的**網(wǎng)絡(luò)也采用了SDH技術(shù)，架設(shè)系統(tǒng)內(nèi)部的SDH光環(huán)路，以承載各種業(yè)務(wù)。比如電力系統(tǒng)，就利用SDH環(huán)路承載內(nèi)部的數(shù)據(jù)、遠(yuǎn)控、視頻、語音等業(yè)務(wù)。 </p> <p> 而對(duì)于組網(wǎng)更加迫切、而又沒有可能架設(shè)**SDH環(huán)路的單位，很多都采用了租用電信運(yùn)營(yíng)商電路的方式。由于SDH基于物理層的特點(diǎn)，單位可在租用電路上承載各種業(yè)務(wù)而不受傳輸?shù)南拗?。承載方式有很多種，可以是利用基于TDM技術(shù)的綜合復(fù)用設(shè)備實(shí)現(xiàn)多業(yè)務(wù)的復(fù)用，也可以利用基于IP的設(shè)備實(shí)現(xiàn)多業(yè)務(wù)的分組交換。SDH技術(shù)可真正實(shí)現(xiàn)租用電路的帶寬保證，安全性方面也優(yōu)于VPN等方式。一般來說，SDH可提供E1、E3、STM-1或STM-4等接口，完全可以滿足各種帶寬要求。同時(shí)在價(jià)格方面，也已經(jīng)為大部分單位所接受。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，服務(wù)周到，產(chǎn)品質(zhì)量，信譽(yù)良好。
