摘要
分布式光纤拉曼放大器(DFRA)因其特有的在线、宽带、低噪声等特点越来越引起人们的重视。利用其在线以及低噪声的特点,将其用作远程光纤水听器(FOH)系统的在线放大器,并测量引入分布式光纤拉曼放大前后系统噪声的变化情况。实验结果表明,分布式光纤拉曼放大器作为在线放大器应用于远程光纤水听器系统后,系统的强度噪声和相位噪声的增加量均小于2 dB。同时,将分布式光纤拉曼放大器与目前广泛应用的掺铒光纤放大器(EDFA)进行对比,发现前者具有更好的噪声性能。因此,分布式光纤拉曼放大器可用作远程光纤水听器系统的在线光放大器。
Abstract
The distributed fiber Raman amplifier (DFRA) is more and more attractive for its particular virtues such as in-line,wideband and low noise etc. Because of the virtues of in-line and low noise,DFRA is used as the in-line amplifier in long-distance fiber optic hydrophone (FOH) and to measure the change of noise. The experimental results show that the increases of intensity noise and phase noise are below 2 dB. Meanwhile,compared with erbium doped fiber amplifier (EDFA),DFRA has better performances when it is used as the in-line amplifier in the remote FOH system. So DFRA can be used as the in-line amplifier in long-distance FOH.
