DVS Coherent Receiver Module DCRM-80M-A
The DVS coherent receiver module targets amplitude-demodulated distributed fiber vibration sensing (DVS). It combines high-SNR coherent detection with an amplitude output signal, allowing direct use in DVS systems without changing the demodulation algorithm. Internal analog-signal noise reduction further improves SNR, reducing the need for optical amplification modules and lowering system cost.
