style="text-indent:25px">光纖在光傳輸中的應用根據(jù)傳輸設備的不同,光纖線路在光傳輸網(wǎng)絡中主要有兩種應用:一種為數(shù)字傳輸,一般為PDH、SDH制式。PDH目前較少用于廣播電視傳輸,多用于數(shù)據(jù)傳輸。SDH多用于組建干線傳輸網(wǎng),也是目前廣電系統(tǒng)采用的傳統(tǒng)模式。另一種為AM模擬傳輸,AM模擬有線電視光傳輸系統(tǒng)又可分為直接調(diào)制調(diào)幅和外調(diào)制調(diào)幅系統(tǒng)。直接調(diào)制調(diào)幅系統(tǒng)是半導體、激勵器直接將光強度調(diào)制,將調(diào)頻電信號轉(zhuǎn)換成調(diào)幅光信號進行傳輸。(DFB)激勵器,其光譜線窄、線性好、輸出功率高、光波長為1310nm,目前使用**多,適用于中短距離傳輸。為廣播電視系統(tǒng)傳輸?shù)闹鞴饫w的連接分為熔接和磨接,無論何種連接都會產(chǎn)生接頭損耗。1310nm的光纖衰減系數(shù)為0.35dB/km。無論信號傳輸遠近,光纜的連接都需要進行光纖熔接,其接頭熔接損耗一般在0.05dB以下。因此在計算光纖自動損耗時還應考慮接頭和其他損耗(2km一般取1dB)。</p><p> SDH 光傳輸設備 </p> <p> SDH（Synchronous Digital Hierarchy，同步數(shù)字系列） </p> <p> 是 PDH 的改進版，它的發(fā)明是電信傳輸體制的**之一，原因在于它可以對同步信號進行傳送、分插、交叉連接和復用，不僅可以通過衛(wèi)星、光纖，還可以微波等進行傳送，是一種新的傳輸體制。SDH 光纖通信技術(shù)在電力系統(tǒng)中廣泛應用，而且在不斷迅速發(fā)展，但是要想保障電力通信網(wǎng)的可靠，就必須保證網(wǎng)絡設備的正常運轉(zhuǎn)，但是設備的故障在所難免，因此，有必要提高對網(wǎng)絡設備的維護能力，出現(xiàn)問題可以及時解決，這樣就能使其更好的為電力的網(wǎng)絡建設和信息傳輸服務。因此，有必要提高通信維護人員的理論水平，提高其的業(yè)務熟練度，比如：掌握和 SDH 相關(guān)的基本理論知識、出現(xiàn)問題時各種警告代號的含義和解決措施和警告信號的來龍去脈和影響等等。同時還要熟悉網(wǎng)絡的基本概念，比如系統(tǒng)配置，數(shù)據(jù)的采集和傳輸，同時加強分析故障和解決故障的能力。 </p> <p> <br />

光傳輸設備的***使用，因此，隨時都有報警的發(fā)生，正確掌握各種報警的含義和特征有利于故障的定位和解決。因為，系統(tǒng)故障時，網(wǎng)管都會記錄各種報警，包括發(fā)生的時間、位置以及其他設備的表現(xiàn)，根據(jù)這些特征結(jié)合開銷字節(jié)和警告原理機制，對故障的排除十分有用。怎樣才能更好的使用報警分析法，關(guān)鍵是及時準確獲取報警信息。因此，有必要了解故障的來源，故障的來源一方面是網(wǎng)管的記錄，這個來源非常容易也比較詳實，而且可以前后對比，通盤考慮，方便故障的排除；另一方面是觀察和記錄設備的指示燈。雖然這種方法具有時效性，但是比較片面，不能反映設備過去情況，不夠***。因此在運用報警分析法時一定要綜合考慮。深圳市騰云科創(chuàng)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。湖北SDH設備華為2路交換式千兆以太網(wǎng)處理板</p><p
