Coherent Detection Module for Distributed Fiber Optic Vibration/Sound Detection (DVS/DAS) and Wind Radar.It is characterized by high signal-to-noise ratio, high reliability and easy integration.
The module has 2 FC input ports for receiving intrinsic and detected optical signals from coherent detection systems. A high performance coupler and balanced photodetector are integrated inside the module.
The CD-DAS model directly outputs the output value of a balanced photodetector. The CD-DVS model is designed for signal de-envelope output processing, and the two different signal processing methods make it easier to use for various coherent detection systems.
Module size 80x54x21.5mm, working voltage 12V, power supply using terminal block. Module output interface for sma female, module response wavelength for 1000-1700nm, typical application for 1550nm, internal smf-28 single-mode fiber, the module adopts AC coupling output, there are four types of bandwidth models can be selected.
