如圖像監(jiān)控、實時數(shù)據(jù)采集、實時控制、各種管理信息系統(tǒng)(MIS) 等,原先采用窄帶數(shù)據(jù)網承載的業(yè)務也逐步轉移到寬帶數(shù)據(jù)網上。除此之外, 電力通信**網本身還具有一些特點: </p> <p> (1) 電力通信網基本上應以光纖通信為主, 以微波通信作備份或補充。 </p> <p> (2) 光纖網絡拓撲結構復雜, 整個網絡節(jié)點數(shù)非常多, 需要傳輸設備有很強的組網和網絡管理能力,且對設備的可靠性要求非常高。 </p> <p> (3) 電力系統(tǒng)所敷設光纜通常芯數(shù)較少, 考慮到今后可能作為電信運營商, 應盡量節(jié)約光纖通信系統(tǒng)所占用的光纖芯數(shù)。 </p> <p> (4) 為滿足整個電力部門目前和將來的所有通信需求, 需要做到話音、視頻和數(shù)據(jù)多網融合。 </p> <p> （5) 目前的業(yè)務接口需求主要有POTS、2W/4W、E&M、V.24、V.35、ISDN、E1、E3/T 3、10Mb/100Mb以太網接口等, 未來的業(yè)務需求大,多基于寬帶數(shù)據(jù)網。采用基于SDH 和MSTP, 可使調度網實現(xiàn)計算機網絡的遠程互聯(lián), 在SDH平臺上實現(xiàn)以太網業(yè)務傳送功能, 從而實現(xiàn)二網合一, 且極大地降低網絡建設成本。湖北SDH光端機烽火 E1板卡分/插復用器用于SDH傳輸網絡的轉接站點處。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

PCM綜合接入設備介紹：FA16接入設備｜BX10接入設備 </p> <p> <br /> </p> 以太網業(yè)務的接入和傳送應用,支持端口捆綁( IEEE802. 3ad) 和生成樹算法( IEEE802.1D) , 支持VLAN ( IEEE802. 1Q ) 和QoS ( IEEE802.1p ) , 可以直接提供10Mb/100Mb自適應以太網接口, 通過內置2 層、3

（1）由于SDH有多種網絡拓撲結構，它所組成的網絡非常靈活，它能增強網監(jiān)，運行管理和自動配置功能，優(yōu)化了網絡性能，同時也使網絡運行靈活、安全、可靠，使網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構的網絡，十分靈活； </p> <p> （3）SDH并不專屬于某種傳輸介質，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就是采用SDH，而且它也便于與光纖電纜混合網(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上采用各種網絡技術，支持ATM或IP傳輸； </p> <p> （5）SDH是嚴格同步的，從而保證了整個網絡穩(wěn)定可靠，誤碼少，且便于復用和調整； </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)網成本。 </p> <p> <br /> </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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣西光傳輸設備SDH烽火STM-1,烽火"
