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(wǎng)承載的業(yè)務也逐步轉(zhuǎn)移到寬帶數(shù)據(jù)網(wǎng)上。除此之外, 電力通信**網(wǎng)本身還具有一些特點: </p> <p> (1) 電力通信網(wǎng)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(wǎng)絡拓撲結(jié)構(gòu)復雜, 整個網(wǎng)絡節(jié)點數(shù)非常多, 需要傳輸設備有很強的組網(wǎng)和網(wǎng)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(wǎng)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，重慶銷售光傳輸設備烽火PEOW、10Mb/100Mb以太網(wǎng)接口等, 未來的業(yè)務需求大,多基于寬帶數(shù)據(jù)網(wǎng)。采用基于SDH 和MSTP, 可使調(diào)度網(wǎng)實現(xiàn)計算機網(wǎng)絡的遠程互聯(lián), 在SDH平臺上實現(xiàn)以太網(wǎng)業(yè)務傳送功能，重慶銷售光傳輸設備烽火PEOW, 從而實現(xiàn)二網(wǎng)合一，重慶銷售光傳輸設備烽火PEOW, 且極大地降低網(wǎng)絡建設成本。星形網(wǎng)絡拓撲是將網(wǎng)中一網(wǎng)元做為中心節(jié)點設備與其他各網(wǎng)元節(jié)點相連。重慶銷售光傳輸設備烽火PEOW</p><div style="width:100%;text-align: center;"><img

通過內(nèi)置2 層、3 層以太網(wǎng)交換機實現(xiàn)統(tǒng)計復用, 并且支持VC212 虛級聯(lián), 帶寬從1～ 48 個2M b平滑設置。<p> <p> 近些年，點播電視、多媒體業(yè)務和其他寬帶業(yè)務如雨后春筍般紛紛出現(xiàn)，為SDH應用在接入網(wǎng)中提供了廣闊的空間。SDH技術(shù)應用于接入網(wǎng)的好處是：1）對于要求高可靠、高質(zhì)量業(yè)務的大型企事業(yè)用戶，SDH可以提供較為理想的網(wǎng)絡性能和業(yè)務可靠性。2）可以將網(wǎng)管范圍擴展至用戶端，簡化維護工作。3）利用SDH固有靈活性，可使網(wǎng)絡運營者更快、更有效地提供用戶所需的長期和短期業(yè)務需求。 </p> <p> 從技術(shù)上來看，接入層的相對帶寬需求較小，需要提供IP、TDM，可能還有ATM等綜合業(yè)務傳送。以SDH 系統(tǒng)為基礎(chǔ)并能夠提供IP 、ATM 傳送與處理的系統(tǒng)（包括TDM、IP與ATM接口，甚至包括IP 和ATM 交換模塊）將是解決接入層傳送的主要方法，這種方式可廉價地在一個業(yè)務提供點（POP）上提供高質(zhì)量專線、ATM 、IP 等業(yè)務的接入、傳送和保護。 </p> </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:

二纖單向通道保護環(huán)，無論從實現(xiàn)控制的復雜性，還是設備的開發(fā)和制作難度來說，都是各種倒換環(huán)中**簡單的。由于它不涉及APS的協(xié)議處理過程，因而業(yè)務倒換時間也**短。二纖雙向復用段保護環(huán)的控制邏輯和設備開發(fā)制作則是各種倒換環(huán)中**復雜的。 </p> <p> 兼容性 </p> <p> 二纖單向通道保護環(huán)*使用已經(jīng)完全預定好了的規(guī)則，由通道AIS信號來觸發(fā)倒換，與現(xiàn)行SDH標準完全相容，因而也容易滿足多廠家產(chǎn)品兼容性要求。 </p> <p> 二纖雙向復用段保護環(huán)使用APS協(xié)議控制倒換，而APS協(xié)議尚未標準化，所以復用段倒換環(huán)目前都不能滿足多廠家產(chǎn)品兼容性的要求。 </p> </p> <p> <br /> 電力網(wǎng)的發(fā)展對電力系統(tǒng)**通信網(wǎng)提出了更高的要求。貴州全新光傳輸設備烽火Citrans 550F</p><p style="text-indent:25px">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；重慶銷售光傳輸設備烽火PEOW</p><p style="text-indent:25px">根據(jù)電力通信點多面廣, 可靠性要求高的特點, 主干傳輸網(wǎng)可采用光纖自愈環(huán)的網(wǎng)絡拓撲結(jié)構(gòu), 也可以采用雙環(huán)相切、多環(huán)相切的主干網(wǎng)絡拓撲結(jié)構(gòu), 采用相切環(huán)時可在兩環(huán)相切的節(jié)點上采用雙環(huán)網(wǎng)元設備交叉保護, 克服雙環(huán)相切時節(jié)點保護可靠性差的問題。支路可根據(jù)實際需要采用鏈形、星形、樹形等結(jié)構(gòu)。另外, 采用SDH 設備的光纖自愈環(huán)可實現(xiàn)多種形式的通道保護, 而且SDH 光纖環(huán)有較強的自愈能力。所謂自愈就是指在網(wǎng)絡發(fā)生故障(例如光纖斷裂)時, 無需人為干預, 網(wǎng)絡能在極短的時間內(nèi)( ITU 2T規(guī)定為50ms 以內(nèi)) 自動恢復傳輸, 使用戶幾乎感覺不到網(wǎng)絡出了故障。傳統(tǒng)的組網(wǎng)概念中, 提高傳輸設備利用率是**關(guān)鍵的, 為了增加線路的占空系數(shù), 在每個節(jié)點都建立了許多直接通道, 致使網(wǎng)絡結(jié)構(gòu)非常復雜。而利用SDH組網(wǎng), 使用SDH提供的豐富的開銷字節(jié), 就可以極大簡化網(wǎng)絡結(jié)構(gòu), 實現(xiàn)強大的OAM功能, 降低傳輸費用并支持新業(yè)務的發(fā)展, 這正符合了現(xiàn)代通信發(fā)展的目標。重慶銷售光傳輸設備烽火PEOW</p><p
