Data Acquisition Card for Distributed Acoustic Fiber Sensing (DAS) with Pulse Output sends TTL pulses directly to the AOM driver, eliminating the need for an additional pulse generator and greatly reducing system complexity.
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.
