InGaAs Ultra-Low Noise Balanced Detector UBD-2.5G-A

The UBD series ultra-low noise balanced detection module is an upgraded product based on the original MBD series. Compared with the original MBD series, its background noise is significantly reduced under the same other parameters. Under the same bandwidth and gain conditions, its background noise is about one-third of the MBD series module, so it has higher sensitivity and higher signal-to-noise ratio.

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

Application area：Distributed fiber optic sensing、 Laser wind radar、 Optical coherence tomography、 Spectral measurement、 Level optical pulse detection
