光纖通信技術(shù)不僅信息傳輸快,容量較大,其損耗也降低了。綜合來(lái)說(shuō),光纖技術(shù)將成為未來(lái)社會(huì)信息傳輸?shù)闹鲗?dǎo)工具。如下對(duì)詳細(xì)的特點(diǎn)進(jìn)行闡述。 </p> <p> 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(duì)于單波長(zhǎng)光纖通信系統(tǒng),由于終端設(shè)備的電子瓶頸效應(yīng)而不能發(fā)揮光纖帶寬大的優(yōu)勢(shì)。通常采用各種復(fù)雜技術(shù)來(lái)增加傳輸?shù)娜萘?特別是現(xiàn)在的密集波分復(fù)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(zhǎng)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(lái)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(guò)光纖通信系統(tǒng)可以跨越更大的無(wú)中繼距離;對(duì)于一個(gè)長(zhǎng)途傳輸線路,由于中繼站數(shù)目的減少,系統(tǒng)成本和復(fù)雜性可**降低。 </p> <p> 1.3抗電磁干擾能力強(qiáng)光纖通信技術(shù)在實(shí)際的應(yīng)用中其抗電磁干擾的能力非常強(qiáng)。因?yàn)槠湓牧喜捎玫氖悄透g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(jìn)能源的綜合利用。在應(yīng)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(hào)的干擾。其可以與高壓電線綜合形成復(fù)合型的光纜。 </p> <p> <br /> </p><p style="text-indent:25px">光纖在光傳輸中的應(yīng)用根據(jù)傳輸設(shè)備的不同,光纖線路在光傳輸網(wǎng)絡(luò)中主要有兩種應(yīng)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(dǎo)體、激勵(lì)器直接將光強(qiáng)度調(diào)制,將調(diào)頻電信號(hào)轉(zhuǎn)換成調(diào)幅光信號(hào)進(jìn)行傳輸。(DFB)激勵(lì)器,其光譜線窄、線性好、輸出功率高、光波長(zhǎng)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(wú)論何種連接都會(huì)產(chǎn)生接頭損耗。1310nm的光纖衰減系數(shù)為0.35dB/km。無(wú)論信號(hào)傳輸遠(yuǎn)近,光纜的連接都需要進(jìn)行光纖熔接,其接頭熔接損耗一般在0.05dB以下。因此在計(jì)算光纖自動(dòng)損耗時(shí)還應(yīng)考慮接頭和其他損耗(2km一般取1dB)。中興SDH光傳輸設(shè)備，光端機(jī)。認(rèn)準(zhǔn)深圳市騰云科創(chuàng)信息咨詢有限公司。</p><div
