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 相關的基本理論知識，深圳華為微波RTN380設備，深圳華為微波RTN380設備、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，深圳華為微波RTN380設備。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 />

style="text-indent:25px">光纖通信技術的特點--頻帶極寬,通信容量大。光纖可利用的帶寬約為50000GHz,比銅線或電纜的傳輸帶寬大得多,對于傳輸各種寬頻帶信息具有十分重要的意義,否則,無法滿足未來寬帶綜合業(yè)務數(shù)字網(wǎng)(B-ISDN)發(fā)展的需要。對于單波長光纖通信系統(tǒng),由于終端設備的電子瓶頸效應而不能發(fā)揮光纖帶寬大的優(yōu)勢。通常采用各種復雜技術來增加傳輸?shù)娜萘?特別是現(xiàn)在的密集波分復用技術極大地增加了光纖的傳輸容量。目前,單波長光纖通信系統(tǒng)的傳輸速率一般在2.5Gbps10Gbps。廣州華為Metro2050專業(yè)銷售SDH光傳輸設備，PTN設備，OTN設備。認準深圳市騰云科創(chuàng)信息咨詢有限公司！</p><div

我國光通信行業(yè)技術不斷提升，傳輸網(wǎng)絡更新升級速度加快，使得市場對光傳輸設備的功能與性能要求不斷提高。作為光通信系統(tǒng)的基礎與關鍵部件，光傳輸設備行業(yè)進入門檻正在不斷提高，市場進一步向**企業(yè)靠攏，實力較弱的企業(yè)生存壓力將日益增大。 </p> <p> 我國已經(jīng)進入5G商業(yè)化應用階段，5G網(wǎng)絡建設速度加快；我國大數(shù)據(jù)、云計算行業(yè)快速發(fā)展，數(shù)據(jù)量迅速增多，數(shù)據(jù)中心的建設規(guī)模不斷增大；萬物互聯(lián)時代已經(jīng)到來，設備之間的信息傳遞對網(wǎng)絡的要求不斷提高。在多重因素的作用下，我國光通信系統(tǒng)建設速度將持續(xù)快速增長，拉動我國光傳輸設備需求繼續(xù)快速上升。 </p> <p> 通信行業(yè)分析人士表示，光傳輸設備是光通信系統(tǒng)的重要組成部分，在信息化時代背景下，其需求持續(xù)快速增長。我國光傳輸設備行業(yè)經(jīng)過不斷發(fā)展，在研發(fā)實力、技術工藝、生產(chǎn)能力等方面不斷進步，已經(jīng)達到國際先進水平，在全球市場中具有較強競爭優(yōu)勢。在5G、大數(shù)據(jù)、物聯(lián)網(wǎng)時代到來的情況下，我國市場對光傳輸設備的需求仍將保持快速增長態(tài)勢，光傳輸設備行業(yè)未來發(fā)展前景依然廣闊。 </p><p> 根據(jù)新思界產(chǎn)業(yè)研究中心發(fā)布的《2019-2023年光傳輸設備行業(yè)深度市場調(diào)研及投資策略建議報告》顯示，光傳輸設備具有傳輸距離遠、信號不易丟失等優(yōu)點，應用范圍日益廣闊，市場規(guī)模持續(xù)快速擴大。2013-2018年，我國光傳輸設備市場規(guī)模年均復合增長率為10.4%，2018年達到890億元左右，預計到2021年，我國光傳輸設備市場規(guī)模將接近1200億元，行業(yè)發(fā)展前景廣闊。 </p> <p> 在中國市場中，光傳輸設備技術較為先進的企業(yè)主要有華為、中興、烽火科技等。其中，華為在全球光傳輸設備市場中處于**地位，中興與烽火科技也具有較強國際競爭力。整體來看，我國光傳輸設備行業(yè)在全球市場中競爭優(yōu)勢較好。 </p> <p> <br />

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)。深圳市騰云科創(chuàng)專業(yè)從事華為傳送網(wǎng)設備,中興承載網(wǎng)設備光端機等通信產(chǎn)品購銷！廣東華為EXCSA增強型交叉時鐘板</p><p

傳輸距離是指光端機實際可傳輸光信號的比較大距離。這是個標稱數(shù)值，它取決于設備和實際環(huán)境等多種因素,雙纖的光端機一般可傳輸1到120KM,單纖的一般可傳輸1到80KM。光端機出現(xiàn)電話光端機，其目的是通過光纖來傳輸電話語音的光通信設備，設備可通過一對光纜傳輸1-720路電話，是遠距離傳輸電話，屏蔽機房，電話超市，小區(qū)放號的比較好選擇。專業(yè)銷售SDH光傳輸設備，PTN設備，OTN設備。推薦深圳市騰云科創(chuàng)信息咨詢有限公司，服務周到，產(chǎn)品質(zhì)量，信譽良好。**產(chǎn)品型號：中興ZXMP系列產(chǎn)品：ZXMP
