Product Overview
The polarization diversity receiving module covers the two polarization states of local oscillator and signal light separately, and receives them separately by two high-speed low-noise balance detectors. Integrated Coherent Receiver can solve the problem of coherent polarization well. Coherent Receiver is suitable for distributed optical fiber sensing, laser wind radar, optical coherence tomography and other applications. UPDR is upgraded on the basis of the original PDR series, greatly reducing the background noise, so that the signal to noise ratio of the detection signal is higher.
