SDH并不專屬于某種傳輸介質(zhì)，它可用于雙絞線、同軸電纜，但SDH用于傳輸高數(shù)據(jù)率則需用光纖。這一特點(diǎn)表明，SDH既適合用作干線通道，也可作支線通道。例如，我國的國家與省級有線電視干線網(wǎng)就是采用SDH，而且它也便于與光纖電纜混合網(wǎng)（HFC）相兼容。 </p> <p> 從OSI模型的觀點(diǎn)來看，SDH屬于其比較低層的物理層，并未對其高層有嚴(yán)格的限制，便于在SDH上采用各種網(wǎng)絡(luò)技術(shù)，浙江華為光端機(jī)型號，支持ATM或IP傳輸； </p> <p> SDH是嚴(yán)格同步的，從而保證了整個網(wǎng)絡(luò)穩(wěn)定可靠，誤碼少，且便于復(fù)用和調(diào)整； </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(biāo)準(zhǔn)速率和標(biāo)準(zhǔn)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(biāo)準(zhǔn)，提高了網(wǎng)絡(luò)的可靠性； </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(fù)荷區(qū)內(nèi)的排列非常有規(guī)律，而凈負(fù)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(shí)現(xiàn)了一次復(fù)用的特性，克服了PDH準(zhǔn)同步復(fù)用方式對全部高速信號進(jìn)行逐級分解然后再生復(fù)用的過程，由于**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> 3、由于采用了較先進(jìn)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(qiáng)大，具有較強(qiáng)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(qiáng)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(fèi)和生存能力起到了積極作用； </p> <p> <br /> 現(xiàn)貨供應(yīng)osn2500 價格優(yōu)惠 ,,專業(yè)技術(shù)團(tuán)隊(duì).為廣大行業(yè)用戶提供安裝,調(diào)試,培訓(xùn)等服務(wù).北京華為622m光端機(jī)</p><p style="text-indent:25px">深圳市騰云科創(chuàng)信息咨詢有限公司，成立于2015年專業(yè)從事通信產(chǎn)品購銷以及施工，維護(hù)，計(jì)算機(jī)系統(tǒng)集成施工。浙江華為光端機(jī)型號</p><p> SDH體制是新體制，剛剛誕生10年，**小容量的SDH是155Mb/s叫STM-1有63個E1。4個STM-1復(fù)接成1個STM-4，也叫622,4個STM-4復(fù)接成1個STM-16，叫2.5G,4個STM-16復(fù)接成1個STM-64，叫10G </p> <p> 可見SDH光端機(jī)是大容量光端機(jī). </p> <p> 155,和622是SDH體制里應(yīng)用**多的光端機(jī)。 </p> <p> 一般的光端機(jī)沒有以太網(wǎng)接口, 帶以太網(wǎng)接口的光端機(jī)是近2年市場的新需要 </p> <p> 用1個E1信道可以傳10M以太網(wǎng)信號,用4個E1信道可以傳100M以太網(wǎng)信號 </p> <p> 一般的光端機(jī)沒有V35接口 </p> <p> V35接口也是近2年的市場需要 </p> <p> V35接口是1種同步數(shù)據(jù)接口,速率是NX64kb/s. </p> <p> 通常用1個E1傳輸1路V35接口。 </p> <p> 一般光端機(jī)都有輔助信道。輔助信道是低速的異步數(shù)據(jù)接口,如RS232勤務(wù)電話,用于站間聯(lián)絡(luò),實(shí)際上很少使用很便宜的光端機(jī)沒有勤務(wù)電話,有的甚至沒有異步數(shù)據(jù)。 </p> <p> 網(wǎng)管,就是計(jì)算機(jī)網(wǎng)絡(luò)管理,也叫集中監(jiān)控。將所有站的光端機(jī)的運(yùn)行狀態(tài)信息都接入總局網(wǎng)管室的網(wǎng)管計(jì)算機(jī)里,就是網(wǎng)管。 </p> <p> 一般PDH光端機(jī)沒有網(wǎng)管系統(tǒng)，只能做TM,即點(diǎn)到點(diǎn)網(wǎng)絡(luò)，只有1個光口。 </p> <p> 一般SDH光端機(jī)都有網(wǎng)管系統(tǒng)，即可以做TM方式,也可以做ADM方式,因此可以組成自愈環(huán)網(wǎng)絡(luò)。 </p> <p> 3個以上光方向的工作方式叫DXC,就是交叉連接方式。
