max-height: 320px;" alt="云南光傳輸設備烽火STM-16,烽火" src="https://tyunfile.71360.com/UploadFile/sztykc/637244845103808594/6520524.jpg"></div><p> <br /> </p> <p> SDH的特點 </p> <p> （1）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> （2）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> （3）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> （4）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> （5）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> （6）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 /> </p> <p> <br /> </p><p style="text-indent:25px">1.近年來，SDH作為新一代理想的傳輸體系，具有路由自動選擇能力，上下電路方便，維護、控制、管理功能強，標準統(tǒng)一，便于傳輸更高速率的業(yè)務等優(yōu)點，能很好地適應通信網(wǎng)飛速發(fā)展的需要。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。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，產(chǎn)品維修，計算機系統(tǒng)集成施工。為客戶提供質(zhì)量產(chǎn)品、完善的解決方案，積極響應配合客戶做好售后服務，在業(yè)界贏得廣大客戶認可及一致好評。努力奉獻，您的滿意是我們一直的追求。積極響應配合客戶做好售后服務，在業(yè)界贏得廣大客戶認可及一致好評。努力奉獻，您的滿意是我們一直的追求。</p><div

SDH作為新一代理想的傳輸體系，具有路由自動選擇能力，上下電路方便，維護、控制、管理功能強，標準統(tǒng)一，便于傳輸更高速率的業(yè)務等優(yōu)點，能很好地適應通信網(wǎng)飛速發(fā)展的需要。迄今，SDH得到了空前的應用與發(fā)展。在標準化方面，已建立和即將建立的一系列建議已基本上覆蓋了SDH的方方面面。在干線網(wǎng)和長途網(wǎng)、中繼網(wǎng)、接入網(wǎng)中它開始廣泛應用。且在光纖通信、微波通信、衛(wèi)星通信中也積極地開展研究與應用。 </p> <p> <br /> 它的作用是將支路端口的低速信號復用到線路端口的高速信號STM-N中。云南光傳輸設備烽火STM-16</p><p style="text-indent:25px">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。云南光傳輸設備烽火STM-16</p><p>
