Ultra low noise polarization diversity coherent receiving module 1510-1590nm UPDR series (1300/1060nm optional) >
Ultra-low noise polarization diversity coherent receiver module UPDR-300M-A
Ultra-low noise polarization diversity coherent receiver module UPDR-300M-A
The ultra-low noise polarization diversity receiver module is designed for polarization-sensitive optical fiber sensing applications. This polarization diversity receiver module coherently detects the two polarization states of the local oscillator and signal light separately, using two high-speed low-noise balanced detectors for individual reception. It effectively solves the issue of coherent polarization states. This series is an upgrade based on the original PDR series, significantly reducing the background noise, thereby achieving higher signal-to-noise ratio for detection.
Product features：High bandwidth、 High gain、 Ultra-low noise、 Built-in low-noise isolation power supply
Application area：Fiber optic sensing、 Laser wind radar、 Optical coherence tomography、 Spectral measurement
