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.
GY-DAQA-2510 is a high-performance DAS dedicated data acquisition card, with dual-channel 1GSps synchronous trigger sampling, and comes with AWG function, which can generate 2-channel swept signal output for chirp pulse modulation.
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.
DTS-ETH-250M-2 is a special data acquisition card for DTS of distributed fiber optic temperature measurement system, which adopts Gigabit Ethernet port for data transmission and built-in averaging function with very high signal-to-noise ratio. Each channel supports a maximum of 32768 points acquisition, averaging up to 65536 times, 250M sampling rate, spatial resolution of 0.4 meters.
