Ultra-low Noise High Gain Pulsed PreAmp EDFA
Connet MARS Series Ultra-low Noise High Gain Pulsed PreAmp Erbium-doped Fiber Amplifier (EDFA) uses a unique optical path design with the proprietary ultra-low noise Erbium-doped fiber, featuring with low noise figure and high gain, which can be used for effectively amplifying such weak signal as -50dBm. The comprehensive performance of this EDFA surpasses the similar products in the market.
The ultra-low noise high-gain Erbium-doped amplifier of Connet is suitable for pre-amplification of weak pulse signals, like the pulse signal generated by modulating a continuous seed laser. This EDFA can effectively suppress the ASE and obtain a better signal-to-noise ratio of the amplified signal while maintaining the high gain. It is an ideal fiber amplifier for weak optical signal acquisition that is widely used in coherent communication, heterodyne detection and Coherent Doppler LIDAR systems, etc.
