Polarization diversity coherent reception module (InGaAs balanced photodetector 1510-1590nm, bandwidth 2.5GHz)
Polarization diversity coherent reception module (InGaAs balanced photodetector 1510-1590nm, bandwidth 2.5GHz)
The IdealPhotonics PDR series polarization diversity reception module is designed for polarization-sensitive fiber optic sensing applications. This polarization diversity reception module coherently detects 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 and is suitable for applications in distributed fiber optic sensing, laser wind radar, optical coherence tomography, and other related fields.
Product features：High bandwidth、 High Gain、 Low Noise、 Built-in low-noise isolation power supply
Application area：Optical fiber sensing、 Laser wind radar、 Optical coherence tomography、 Spectral measurement
