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)又可分為直接調制調幅和外調制調幅系統(tǒng)。直接調制調幅系統(tǒng)是半導體、激勵器直接將光強度調制,將調頻電信號轉換成調幅光信號進行傳輸。(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)。</p><p> 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復接成1個STM-4，也叫622,4個STM-4復接成1個STM-16，叫2.5G,4個STM-16復接成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勤務電話,用于站間聯(lián)絡,實際上很少使用很便宜的光端機沒有勤務電話,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，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。 </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 /> 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

由于SDH有多種網(wǎng)絡拓撲結構，它所組成的網(wǎng)絡非常靈活，它能增強網(wǎng)監(jiān)，運行管理和自動配置功能，優(yōu)化了網(wǎng)絡性能，同時也使網(wǎng)絡運行靈活、安全、可靠，使網(wǎng)絡的功能非常齊全和多樣化； </p> <p> SDH有傳輸和交換的性能，它的系列設備的構成能通過功能塊的自由組合，實現(xiàn)了不同層次和各種拓撲結構的網(wǎng)絡，十分靈活； </p> <p> SDH并不專屬于某種傳輸介質，它可用于雙絞線、同軸電纜，但SDH用于傳輸高數(shù)據(jù)率則需用光纖。這一特點表明，SDH既適合用作干線通道，也可作支線通道。例如，我國的國家與省級有線電視干線網(wǎng)就是采用SDH，而且它也便于與光纖電纜混合網(wǎng)（HFC）相兼容。 </p> <p> 從OSI模型的觀點來看，SDH屬于其比較低層的物理層，并未對其高層有嚴格的限制，便于在SDH上采用各種網(wǎng)絡技術，支持ATM或IP傳輸； </p> <p> SDH是嚴格同步的，從而保證了整個網(wǎng)絡穩(wěn)定可靠，誤碼少，且便于復用和調整； </p> <p> 標準的開放型光接口可以在基本光纜段上實現(xiàn)橫向兼容，降低了聯(lián)網(wǎng)成本。 </p>
