Features   Highly Integrated  (UNL, AOM, EDFA, BPD，RAMAN) Working Temperature: -10~50℃ High Reliability and Stability Flexible Control Mode Single / Dual Channel

Distributed fiber Acoustic 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 frequency information, to achieve the detection of sound, 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 DAS integrated module, which integrates self-developed ultra-narrow linewidth laser, linewidth <3KHz, 80M_AOM, pulse amplifier, balanced photodetector. The module is highly integrated, with small size and high reliability.

Features   Built-in DAQ: output temperature directly Sensing Distance：25km(SM), 15km(MM), 5km(High Accuracy) Shorten customer R&D cycle
