Features
DVS Integrated Optical Module
Distributed fiber Vibration Sensing(DAS),based on the principle of phase OTDR, using a single ordinary optical fiber as a transmission, the Rayleigh scattered light inside the fiber to detect, obtain phase and intensity information, to achieve the detection of vibration and other signals, widely used in oil, gas pipelines, perimeter security, high-speed rail transit and other fields.
For the field of distributed fiber optic acoustic sensing, FIBERWDM has launched DVS integrated module, which integrates self-developed ultra-narrow linewidth laser, linewidth <3KHz, 80M_AOM, pulse amplifier, coherence intensity detector, for higher SNR than common detectors. The module is highly integrated, with small size and high reliability.
