InGaAs ultra-low noise balance detector UBD-2G-A

InGaAs ultra-low noise balance detector UBD-2G-A

The UBD series ultra-low noise balanced detection modules are upgraded products based on the previous MBD series. Compared to the original MBD series, the background noise is significantly reduced under the same conditions. With the same bandwidth and gain, the background noise of the UBD series is approximately one-third of that of the MBD series modules, resulting in higher sensitivity and better signal-to-noise ratio.

Product features：Ultra-low noise、 High Gain、 High bandwidth、 Compact structure、 Built-in low-noise isolation power supply

Part Number：--

Application area：Distributed fiber optic sensing、 Laser wind radar、 Optical coherence tomography、 Spectral measurement、 Pulsed light detection
