    • Ultra-low noise polarization diversity coherent reception module UPDR-1G-A

    The ultra-low noise polarization diversity receiver module is designed for polarization-sensitive fiber optic sensing applications. This module coherently processes the two polarization states of the local oscillator and signal light separately, using two high-speed, low-noise balanced detectors for independent reception. It effectively solves the issue of coherent polarization states. This series is an upgrade of the original PDR series, significantly reducing the background noise, thereby providing higher signal-to-noise ratio for signal detection.

    Product features：High Bandwidth、 High Gain、 Ultra-low noise、 Built-in low-noise isolation power supply

    Part Number：--

    Application area：Fiber optic sensing、 Laser wind radar、 Optical coherence tomography、 Spectroscopy
