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，寧夏銷售光傳輸設備烽火2路交換式千兆以太網(wǎng)處理板, 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，寧夏銷售光傳輸設備烽火2路交換式千兆以太網(wǎng)處理板、V.24、V.35、ISDN、E1、E3/T 3、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，寧夏銷售光傳輸設備烽火2路交換式千兆以太網(wǎng)處理板, 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, 從而實現(xiàn)二網(wǎng)合一, 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。寧夏銷售光傳輸設備烽火2路交換式千兆以太網(wǎng)處理板</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

在各種寬帶光纖接入網(wǎng)技術中，采用了SDH技術的接入網(wǎng)系統(tǒng)是應用**普遍的。SDH的誕生解決了由于入戶媒質(zhì)的帶寬限制而跟不上骨干網(wǎng)和用戶業(yè)務需求的發(fā)展,而產(chǎn)生了用戶與**網(wǎng)之間的接入"瓶頸"的問題，同時提高了傳輸網(wǎng)上大量帶寬的利用率。SDH技術自從90年代引入以來，至今已經(jīng)是一種成熟、標準的技術，在骨干網(wǎng)中被***采用，且價格越來越低，在接入網(wǎng)中應用可以將SDH技術在**網(wǎng)中的巨大帶寬優(yōu)勢和技術優(yōu)勢帶入接入網(wǎng)領域，充分利用SDH同步復用、標準化的光接口、強大的網(wǎng)管能力、靈活網(wǎng)絡拓撲能力和高可靠性帶來好處，在接入網(wǎng)的建設發(fā)展中長期受益。

SDH傳輸網(wǎng)是由不同類型的網(wǎng)元通過光纜線路的連接組成的，通過不同的網(wǎng)元完成SDH網(wǎng)的傳送功能：上/下業(yè)務、交叉連接業(yè)務、網(wǎng)絡故障自愈等。下面我們講述SDH網(wǎng)中常見網(wǎng)元的特點和基本功能。 </p> <p> TM——終端復用器 </p> <p> 終端復用器用在網(wǎng)絡的終端站點上，例如一條鏈的兩個端點上，它是一個雙端口器件。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，或從STM-N的信號中分出低速支路信號。請注意它的線路端口輸入/輸出一路STM-N信號，而支路端口卻可以輸出/輸入多路低速支路信號。在將低速支路信號復用進STM-N幀（將低速信號復用到線路）上時，有一個交叉的功能，例如：可將支路的一個STM-1信號復用進線路上的STM-16信號中的任意位置上，也就是指復用在1~16個STM-1的任一個位置上。將支路的2Mbit/s信號可復用到一個STM-1中63個VC12的任一個位置上去。對于華為設備，TM的線路端口（光口）一般以西向端口默認表示的。 </p><p> 電源系統(tǒng)SDH設備采用一48伏直流電源，工作電壓應滿足：輸入電壓范圍是-40V至-57V；電話衡量雜音電壓<2mV；峰峰值雜音電壓(0．300Hz)_<400mV。 </p> <p> 根據(jù)公式：電流=功率／電壓。各設備正常工作時的比較大電流等于滿配置功耗除以工作電壓。比較大電流再加上適當富余量取整可得所需熔絲大小。 </p> <p> 時鐘同步系統(tǒng) </p> <p> SDH網(wǎng)元時鐘源的種類 </p> <p> (1)外部時鐘源——由SETPI功能塊提供輸入接口； </p> <p> (2)線路時鐘源一由SPI功能塊從STM．N線路信號中提??； </p> <p> (3)支路時鐘源——由PPI功能塊從PDH支路信號中提取，不過該時鐘一般不用，因為SDH／PDH網(wǎng)邊界處的指針調(diào)整會影響時鐘質(zhì)量； </p> <p> (4)設備內(nèi)置時鐘源由SETS功能塊提供。 </p> <p> <br /> 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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

隨著科學技術的不斷發(fā)展,各行各業(yè)為了滿足自身內(nèi)部的需求，將會建設更多，更復雜的**網(wǎng)絡，這些網(wǎng)絡必將承擔更多的任務。 </p> <p> 對于大多數(shù)專網(wǎng)，在目前的技術條件下，則應利用公眾網(wǎng)實現(xiàn)企業(yè)或?qū)I(yè)部門的通信需求。利用公眾網(wǎng)滿足專業(yè)部門的需求具有各種不同的方式。如租用公眾網(wǎng)的光芯或傳輸容量，配置自己的交換設備。這就免除了**困難的光纜輔設工程，比較適用于具有大規(guī)模用戶的企業(yè)。又如委托公眾網(wǎng)**為本企業(yè)或部門使用的虛擬**網(wǎng)，它所提供的功能和容量完全按照用戶的要求進行，這就免除了全部的投資風險和維護工作，應用機動靈活，使用部門可以專心致力于其本行業(yè)的業(yè)務工作。 </p> <p> <br /> 各種PDH支路信號復用進STM-N幀的過程都要經(jīng)歷映射、定位、復用三個步驟。廣東全新光傳輸設備烽火ASON 780B</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。
