DFRA

Meanwhile, comparison tests with EDFA show that DFRA has better performances when it is used as in-line amplifiers in the remote FOH system.

同时将分布式光纤拉曼放大器和掺铒光纤放大器进行了实验对比，结果表明前者可以作为远程光纤水听器系统的在线放大器，并且具有比后者更好的噪声性能。

Distributed Fiber Raman Amplifier ( DFRA) magnify light signal directly by using transmitted fiber as gain medium.

分布式光纤拉曼放大器（DFRA）利用传输光纤本身作为增益介质来放大光信号。

用DFRA延长无中继海底光缆的传输距离

With increasing DFRA on off gain, Δ OSNR increases first linearly and then logarithmically, resulting in saturation.

指出:随着DFRA开关增益的增加, ΔOSNR会由线性增加逐渐变为对数增加而趋于饱和.
