This module not only has the characteristics of high signal-to-noise ratio of coherent detection, but also the output signal is amplitude signal. It can be directly used in the DVS system without modifying the demodulation algorithm; on the basis of the high signal-to-noise ratio of coherent detection, the analog signal is denoised inside the module, which can improve the signal-to-noise ratio as much as possible, and can reduce the application of the system optical amplification module , reduce system cost. It is very suitable for distributed fiber-optic vibration sensing (DVS) systems based on amplitude demodulation.<\/p>\n\n\n\n<p>Features<\/p>\n\n\n\n<p>High signal-to-noise ratio for coherent detection<br>Can be directly used in DVS system<br>No need to modify the algorithm<br>Reduce system cost<br>Built-in low-noise isolated power supply<\/p>\n\n\n\n<p>Applications<br>Distributed fiber-optic vibration sensing (DVS) based on amplitude demodulation<\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-3 is-cropped\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" width=\"869\" height=\"522\" src=\"https:\/\/beamq.com\/laser\/wp-content\/uploads\/2022\/08\/datasheet-3.png\" alt=\"\" data-id=\"834\" data-link=\"https:\/\/beamq.com\/laser\/polarization-diversity-coherent-receiver-module\/datasheet-3\/\" class=\"wp-image-834\"\/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" width=\"972\" height=\"546\" src=\"https:\/\/beamq.com\/laser\/wp-content\/uploads\/2022\/08\/datasheet-2.png\" alt=\"\" data-id=\"835\" data-link=\"https:\/\/beamq.com\/laser\/polarization-diversity-coherent-receiver-module\/datasheet-2\/\" class=\"wp-image-835\"\/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" width=\"796\" height=\"690\" src=\"https:\/\/beamq.com\/laser\/wp-content\/uploads\/2022\/08\/datasheet.png\" alt=\"\" data-id=\"836\" data-link=\"https:\/\/beamq.com\/laser\/polarization-diversity-coherent-receiver-module\/datasheet\/\" class=\"wp-image-836\"\/><\/figure><\/li><\/ul><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Polarization Diversity Coherent Receiver Module The PDR series polarization diversity receiver modules are aimed at polarization-sensitive optical fiber sensing applications.
