DTS optical path module

Overview
FT-VC-DTS-MC is the optical module of the distributed optical fiber temperature measurement DTS system. This module integrates a pulsed laser, a wavelength division multiplexer, and an avalanche detector, etc. It features a small size, high detection accuracy, and excellent consistency. It can be used for distributed optical fiber temperature measurement and is applied in fields such as power, pipeline monitoring, urban integrated tunnels, warehousing, military industry, and nuclear industry. It is suitable for scenarios where DTS research and development manufacturers combine it with their own acquisition cards.
