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。綜合來說,光纖技術(shù)將成為未來社會信息傳輸?shù)闹鲗?dǎo)工具。如下對詳細(xì)的特點進行闡述。 </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。對于單波長光纖通信系統(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。通常采用各種復(fù)雜技術(shù)來增加傳輸?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(fù)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(yīng)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(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 />

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光端機是大容量光端機. </p> <p> 155,和622是SDH體制里應(yīng)用**多的光端機。 </p> <p> 一般的光端機沒有以太網(wǎng)接口, 帶以太網(wǎng)接口的光端機是近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),實際上很少使用很便宜的光端機沒有勤務(wù)電話,有的甚至沒有異步數(shù)據(jù)。 </p> <p> 網(wǎng)管,就是計算機網(wǎng)絡(luò)管理,也叫集中監(jiān)控。將所有站的光端機的運行狀態(tài)信息都接入總局網(wǎng)管室的網(wǎng)管計算機里,就是網(wǎng)管。 </p> <p> 一般PDH光端機沒有網(wǎng)管系統(tǒng)，只能做TM,即點到點網(wǎng)絡(luò)，只有1個光口。 </p> <p> 一般SDH光端機都有網(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。 </p> <p> <br />

較好的光端機有雙光口雙光口的光端機還分：1個還是2個光方向1個光方向的雙光口，是1+1備份工作的一旦主光纖斷了，輔光口保證工作。 </p> <p> 光口數(shù)量3：雙光口雙方向 </p> <p> 來自左光口的信號1部分落在本地，另1部分繼續(xù)從右光口發(fā)送，這種工作模式叫上下路模式：ADM具有ADM方式的光端機可以組成雙纖自愈環(huán) </p> <p> 雙纖自愈環(huán)的好處 </p> <p> 自愈環(huán)的好處就是，一旦光纜斷了，整個通信不會中斷。光纜正常時，各站間的信息從外環(huán)走端纜后，站1發(fā)向站2方向的信息，改由內(nèi)環(huán)走，當(dāng)光纜接好后，網(wǎng)絡(luò)自動恢復(fù)正常只有具備ADM方式的光端機，才能實現(xiàn)自愈環(huán)。 </p> <p>
