style="text-indent:25px">光纖通信技術(shù)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(shù)來增加傳輸?shù)娜萘?特別是現(xiàn)在的密集波分復用技術(shù)極大地增加了光纖的傳輸容量。目前，四川代理光傳輸設備華為

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)。四川代理光傳輸設備華為

1.1頻帶極寬,通信容量大光纖比銅線或電纜有大得多的傳輸帶寬,光纖通信系統(tǒng)的于光源的調(diào)制特性、調(diào)制方式和光纖的色散特性。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(shù)來增加傳輸?shù)娜萘?特別是現(xiàn)在的密集波分復用技術(shù)極大地增加了光纖的傳輸容量。 </p> <p> 1.2損耗低,中繼距離長商品石英光纖損耗可低于0~20dB/km,這樣的傳輸損耗比其它任何傳輸介質(zhì)的損耗都低;若將來采用非石英系統(tǒng)極低損耗光纖,其理論分析損耗可下降的更低。這意味著通過光纖通信系統(tǒng)可以跨越更大的無中繼距離;對于一個長途傳輸線路,由于中繼站數(shù)目的減少,系統(tǒng)成本和復雜性可**降低。 </p> <p> 1.3抗電磁干擾能力強光纖通信技術(shù)在實際的應用中其抗電磁干擾的能力非常強。因為其原材料采用的是耐腐蝕性的石英制成的,用這種材料制成還節(jié)省了能源的消耗,促進能源的綜合利用。在應用中不僅抗干擾,其絕緣性也非常好。不受雷電與其它通信信號的干擾。其可以與高壓電線綜合形成復合型的光纜。 </p> <p> <br />

對于組網(wǎng)更加迫切、而又沒有可能架設**SDH環(huán)路的單位，很多都采用了租用電信運營商電路的方式。由于SDH基于物理層的特點，單位可在租用電路上承載各種業(yè)務而不受傳輸?shù)南拗啤３休d方式有很多種，可以是利用基于TDM技術(shù)的綜合復用設備實現(xiàn)多業(yè)務的復用，也可以利用基于IP的設備實現(xiàn)多業(yè)務的分組交換。SDH技術(shù)可真正實現(xiàn)租用電路的帶寬保證，安全性方面也優(yōu)于VPN等方式。在**機.關(guān)和對安全性非常注重的企業(yè)，SDH租用線路得到了***的應用。一般來說，SDH可提供E1、E3、STM-1或STM-4等接口，完全可以滿足各種帶寬要求。同時在價格方面，也已經(jīng)為大部分單位所接受。 </p> <p> 綜上所述，SDH以其明顯的優(yōu)越性已成為傳輸網(wǎng)發(fā)展的主流。SDH技術(shù)與一些先進技術(shù)相結(jié)合，如光波分復用（WDM）、ATM技術(shù)、Internet技術(shù)（IP over
