C & L-Band Separate Raman Fiber Amplifier
RFA7000
-
Hangzhou Huatai Optic Tech. Co., Ltd.
1. Erbium-doped Fiber Amplifier, due to the multiple cascades and the accumulation of noise caused by spontaneous emission, will reduce the system CNR greatly and thus it will limit the transmission capacity and distance of the system. Raman Fiber Amplifier (RFA) is a newly designed fiber amplifier based on Stimulated Raman Scattering (SRS) effect. It is considered as the core technology of new generation DWDM fiber over-long communication. Compared with Erbium-Doped Fiber Amplifier, Raman amplifier has the advantage of low Noise Figure (NF), wider gain bandwidth, flexible gain spectral region and stable temperature. It is the only device that can operate in 1300~1600 nm.

100mA One-Channel Amplifiers
-
Piezo amplifiers/controllers are designed for high precision positioning of low-voltage piezo actuators. These amplifiers are tuned for extremely high output stability and extremely low signal noise at the output. A low amplifier signal-to-noise ratio is very important because it determines the total resolution of the actuator. The nearly unlimited resolution of piezo-electric actuators using these amplifiers results in ultra-precise movement.
