光口數(shù)量1：點(diǎn)到點(diǎn)方式 </p> <p> 便宜的光端機(jī)只有1個(gè)光接口1對設(shè)備，組成點(diǎn)到點(diǎn)工作方式也叫終端方式：TM </p> <p> 光口數(shù)量2：雙光口單方向 </p> <p> 較好的光端機(jī)有雙光口雙光口的光端機(jī)還分：1個(gè)還是2個(gè)光方向1個(gè)光方向的雙光口，是1+1備份工作的一旦主光纖斷了，輔光口保證工作。 </p> <p> 光口數(shù)量3：雙光口雙方向 </p> <p> 來自左光口的信號1部分落在本地，另1部分繼續(xù)從右光口發(fā)送，這種工作模式叫上下路模式：ADM具有ADM方式的光端機(jī)可以組成雙纖自愈環(huán) </p> <p> 雙纖自愈環(huán)的好處 </p> <p> 自愈環(huán)的好處就是，一旦光纜斷了，整個(gè)通信不會(huì)中斷。光纜正常時(shí)，各站間的信息從外環(huán)走端纜后，站1發(fā)向站2方向的信息，改由內(nèi)環(huán)走，當(dāng)光纜接好后，網(wǎng)絡(luò)自動(dòng)恢復(fù)正常只有具備ADM方式的光端機(jī)，才能實(shí)現(xiàn)自愈環(huán)。 </p> <p> 光口數(shù)量4：多光口多光方向 </p> <p> 比較好用的光端機(jī)是SDH，具有多個(gè)光方向但是價(jià)格就貴了很多在SDH設(shè)備中在詳細(xì)論述后面給出1個(gè)網(wǎng)絡(luò)圖，是各種方式的**。 </p> <p> 深圳騰云科創(chuàng)信息咨詢有限公司，擁有專業(yè)的技術(shù)團(tuán)隊(duì)，由

對于組網(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。在**機(jī).關(guān)和對安全性非常注重的企業(yè)，SDH租用線路得到了***的應(yīng)用。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。
