摘要
本文介绍了一种改善环形腔掺铒光纤激光器信噪比的简单方法,信噪比提高了 5.2 dB.用该激光器做WDM系统的光源,完成了 1.2 Gb/s的归零码和 25GHz、5 GHz的模拟信号经 100km的传输实验.
A method to improve ring erbium-doped fiber laser's SNR is presented .An EDFL's SNR is improved 5.2 dB. The laser has been used in an experimental WDM transmission system to serve as the light source. It is qualified for the transmission of 1.2 Gb/s RZ, 2.5 GHz analogue signal and 5 GHz analogue signal over 100 km.
