RA系列拉曼放大器是光纖放大器，設計用來恢復在光纖中遭受的光損失，這樣來擴展傳輸距離。RA系列是被設計放大超長距離傳輸?shù)?/SPAN>DWDM網絡的光信號。RA也能夠被結合成HFC/CATV網絡增加模擬和數(shù)字通道的傳輸范圍。
RA系列拉曼放大器是用Telcordia資質的元件構成的，確保15年以上的連續(xù)操作壽命。它們是由我們的標準3年有限產品保修支持的。
應用
• DWDM
• 超長距離傳輸
• HFC網絡
• 海底鏈路
特征
• 在10G/40G傳輸聯(lián)系支持達到80DWDM通道
• 在HFC/CATV傳輸中擴展QAM數(shù)字和模擬通道
• 增益達到13dB
• -1.3dB的有效噪聲系數(shù)
