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 /> </p></p><p><img
