對于組網(wǎng)更加迫切、而又沒有可能架設**SDH環(huán)路的單位，很多都采用了租用電信運營商電路的方式。由于SDH基于物理層的特點，單位可在租用電路上承載各種業(yè)務而不受傳輸?shù)南拗?。承載方式有很多種，可以是利用基于TDM技術(shù)的綜合復用設備實現(xiàn)多業(yè)務的復用，也可以利用基于IP的設備實現(xiàn)多業(yè)務的分組交換。SDH技術(shù)可真正實現(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.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。同時在價格方面，也已經(jīng)為大部分單位所接受。 </p> <p> 綜上所述，SDH以其明顯的優(yōu)越性已成為傳輸網(wǎng)發(fā)展的主流。SDH技術(shù)與一些先進技術(shù)相結(jié)合，如光波分復用（WDM）、ATM技術(shù)、Internet技術(shù)（IP over SDH）等，使SDH網(wǎng)絡的作用越來越大。SDH已被各國列入21世紀高速通信網(wǎng)的應用項目，是電信界公認的數(shù)字傳輸網(wǎng)的發(fā)展方向，具有遠大的商用前景。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">光纖通信技術(shù)的特點--頻帶極寬,通信容量大。光纖可利用的帶寬約為50000GHz,比銅線或電纜的傳輸帶寬大得多,對于傳輸各種寬頻帶信息具有十分重要的意義,否則,無法滿足未來寬帶綜合業(yè)務數(shù)字網(wǎng)(B-ISDN)發(fā)展的需要。對于單波長光纖通信系統(tǒng),由于終端設備的電子瓶頸效應而不能發(fā)揮光纖帶寬大的優(yōu)勢。通常采用各種復雜技術(shù)來增加傳輸?shù)娜萘?特別是現(xiàn)在的密集波分復用技術(shù)極大地增加了光纖的傳輸容量。目前,單波長光纖通信系統(tǒng)的傳輸速率一般在2.5Gbps10Gbps。專業(yè)銷售SDH光傳輸設備，PTN設備，OTN設備。認準深圳市騰云科創(chuàng)信息咨詢有限公司！</p><div

1、SDH傳輸系統(tǒng)在國際上有統(tǒng)一的幀結(jié)構(gòu)，數(shù)字傳輸標準速率和標準的光路接口，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)務信號，形成了全球統(tǒng)一的數(shù)字傳輸體制標準，提高了網(wǎng)絡的可靠性； </p> <p> 2、SDH接入系統(tǒng)的不同等級的碼流在幀結(jié)構(gòu)凈負荷區(qū)內(nèi)的排列非常有規(guī)律，而凈負荷與網(wǎng)絡是同步的，它利用軟件能將高速信號一次直接分插出低速支路信號，實現(xiàn)了一次復用的特性，克服了PDH準同步復用方式對全部高速信號進行逐級分解然后再生復用的過程，由于**簡化了DXC，減少了背靠背的接口復用設備，改善了網(wǎng)絡的業(yè)務傳送透明性； </p> <p> 3、由于采用了較先進的分插復用器（ADM）、數(shù)字交叉連接（DXC）、網(wǎng)絡的自愈功能和重組功能就顯得非常強大，具有較強的生存率。因SDH幀結(jié)構(gòu)中安排了信號的5%開銷比特，它的網(wǎng)管功能顯得特別強大，并能統(tǒng)一形成網(wǎng)絡管理系統(tǒng)，為網(wǎng)絡的自動化、智能化、信道的利用率以及降低網(wǎng)絡的維管費和生存能力起到了積極作用；

由于SDH有多種網(wǎng)絡拓撲結(jié)構(gòu)，它所組成的網(wǎng)絡非常靈活，它能增強網(wǎng)監(jiān)，運行管理和自動配置功能，優(yōu)化了網(wǎng)絡性能，同時也使網(wǎng)絡運行靈活、安全、可靠，使網(wǎng)絡的功能非常齊全和多樣化； </p> <p> SDH有傳輸和交換的性能，它的系列設備的構(gòu)成能通過功能塊的自由組合，實現(xiàn)了不同層次和各種拓撲結(jié)構(gòu)的網(wǎng)絡，十分靈活； </p> <p> 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模型的觀點來看，SDH屬于其比較低層的物理層，并未對其高層有嚴格的限制，便于在SDH上采用各種網(wǎng)絡技術(shù)，支持ATM或IP傳輸； </p> <p> SDH是嚴格同步的，從而保證了整個網(wǎng)絡穩(wěn)定可靠，誤碼少，且便于復用和調(diào)整； </p> <p> 標準的開放型光接口可以在基本光纜段上實現(xiàn)橫向兼容，降低了聯(lián)網(wǎng)成本。 </p> <p> <br /> 廣西SDH設備華為8路帶交換功能快速以太網(wǎng)處理板</p><p
