The UNL-C-F-M-C34-13-7-1-0-0 is a narrow linewidth 1550nm laser module from YB Photonics. It features an ultra-narrow linewidth (<3kHz) making it ideal for distributed fiber optic sensing systems(DVS/DAS) and wind radar.
This is a data acquisition card for distributed fiber optic vibration monitoring system (DVS) with built-in TTL pulse signal trigger output function to provide signal to the AOM driver, saving extra signal generator (AWG) and reducing the integration difficulty and complexity of the system.
Introduces the configuration of the pulsed laser for DTS temperature sensing, including how to set the ACC and APC modes, the trigger method and the pulse width parameters.
