光纖放大器一般都由增益介質(zhì)、泵浦光和輸入輸出耦合結(jié)構(gòu)組成。目前光纖放大器主要有摻鉺光纖放大器、半導體光放大器和光纖拉曼放大器三種，根據(jù)其在光纖網(wǎng)絡中的應用，光纖放大器主要有三種不同的用途：在發(fā)射機側(cè)用作功率放大器以提高發(fā)射機的功率；在接收機之前作光預放大器以極大地提高光接收機的靈敏度；在光纖傳輸線路中作中繼放大器以補償光纖傳輸損耗，延長傳輸距離。
干線放大器技術特點：
 
*．HYF-860B﹑HYF-750B﹑HYF-550B系列溫度補償寬帶網(wǎng)絡干線放大器采用采用高性能飛利浦CATV專用放大模塊，保證了輸出信號功率大,頻帶寬,增益高,線性好,工作穩(wěn)定。
 
*．前后兩級均衡調(diào)節(jié)電路，使信號電平平坦度好，有效解決電平“鼓包”現(xiàn)象，并且能使電平帶斜率輸出，適用于有線電視遠距離傳輸。
 
*．獨有的集成電路式溫度補償能改善由于高低氣溫差對電纜及放大器的影響，自動控制輸出電平的高低。
 
*．分支型﹑分配型輸出選擇功能適合實際線路的需要，節(jié)省開支；輸出饋電顯示功能，方便實用。
 
*．采用雙面金屬孔化電路板，環(huán)型變壓器電源，使放大器高頻性能優(yōu)異，工作穩(wěn)定可靠。
 
*．CATV專用鋁合金壓鑄噴塑外殼，防雨、散熱、屏蔽特性好。
 
*．220V交流供電或者60V集中饋電型任選。
