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、激勵器直接將光強(qiáng)度調(diào)制,將調(diào)頻電信號轉(zhuǎn)換成調(diào)幅光信號進(jìn)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(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。因此在計算光纖自動損耗時還應(yīng)考慮接頭和其他損耗(2km一般取1dB)。湖北光傳輸設(shè)備價格華為OSN500專業(yè)銷售PTN設(shè)備、OTN設(shè)備、SDH光傳輸設(shè)備。推薦深圳市騰云科創(chuàng)，服務(wù)周到，產(chǎn)品質(zhì)量，信譽(yù)良好！</p><div

光傳輸設(shè)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?yàn)?，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(shè)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(jī)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(zhǔn)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(shí)，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(shè)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(shè)備過去情況，不夠***。因此在運(yùn)用報警分析法時一定要綜合考慮。

SDH體制是新體制，剛剛誕生10年，**小容量的SDH是155Mb/s叫STM-1有63個E1。4個STM-1復(fù)接成1個STM-4，也叫622,4個STM-4復(fù)接成1個STM-16，叫2.5G,4個STM-16復(fù)接成1個STM-64，叫10G </p> <p> 可見SDH光端機(jī)是大容量光端機(jī). </p> <p> 155,和622是SDH體制里應(yīng)用**多的光端機(jī)。 </p> <p> 一般的光端機(jī)沒有以太網(wǎng)接口, 帶以太網(wǎng)接口的光端機(jī)是近2年市場的新需要 </p> <p> 用1個E1信道可以傳10M以太網(wǎng)信號,用4個E1信道可以傳100M以太網(wǎng)信號 </p> <p> 一般的光端機(jī)沒有V35接口 </p> <p> V35接口也是近2年的市場需要 </p> <p> V35接口是1種同步數(shù)據(jù)接口,速率是NX64kb/s. </p> <p> 通常用1個E1傳輸1路V35接口。 </p> <p> 一般光端機(jī)都有輔助信道。輔助信道是低速的異步數(shù)據(jù)接口,如RS232勤務(wù)電話,用于站間聯(lián)絡(luò),實(shí)際上很少使用很便宜的光端機(jī)沒有勤務(wù)電話,有的甚至沒有異步數(shù)據(jù)。 </p> <p> 網(wǎng)管,就是計算機(jī)網(wǎng)絡(luò)管理,也叫集中監(jiān)控。將所有站的光端機(jī)的運(yùn)行狀態(tài)信息都接入總局網(wǎng)管室的網(wǎng)管計算機(jī)里,就是網(wǎng)管。 </p> <p> 一般PDH光端機(jī)沒有網(wǎng)管系統(tǒng)，只能做TM,即點(diǎn)到點(diǎn)網(wǎng)絡(luò)，只有1個光口。 </p> <p> 一般SDH光端機(jī)都有網(wǎng)管系統(tǒng)，即可以做TM方式,也可以做ADM方式,因此可以組成自愈環(huán)網(wǎng)絡(luò)。 </p> <p> 3個以上光方向的工作方式叫DXC,就是交叉連接方式。
