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(dǎo)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(luò)中的應(yīng)用，光纖放大器主要有三種不同的用途：在發(fā)射機(jī)側(cè)用作功率放大器以提高發(fā)射機(jī)的功率；在接收機(jī)之前作光預(yù)放大器以極大地提高光接收機(jī)的靈敏度；在光纖傳輸線路中作中繼放大器以補(bǔ)償光纖傳輸損耗，延長(zhǎng)傳輸距離。
干線放大器技術(shù)特點(diǎn)：
 
*．HYF-860B﹑HYF-750B﹑HYF-550B系列溫度補(bǔ)償寬帶網(wǎng)絡(luò)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(hào)功率大,頻帶寬,增益高,線性好,工作穩(wěn)定。
 
*．前后兩級(jí)均衡調(diào)節(jié)電路，使信號(hào)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(yuǎn)距離傳輸。
 
*．獨(dú)有的集成電路式溫度補(bǔ)償能改善由于高低氣溫差對(duì)電纜及放大器的影響，自動(dòng)控制輸出電平的高低。
 
*．分支型﹑分配型輸出選擇功能適合實(shí)際線路的需要，節(jié)省開(kāi)支；輸出饋電顯示功能，方便實(shí)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。
