The GY-DTS-X is a special DAQ card for DTS system,With 100/200/250MSps sampling rate. It adopts 100Mbps network port for data transmission,Built-in averaging function with a high signal-to-noise ratio. the maximum number of averaging can be up to 65536 times.
The APD modules are based on low-noise avalanche photodiodes made of InGaAs with a built-in pre-amplifier and high voltage supply.A temperature compensation function allows the APD to be operated at constant gain across a wide operating temperature range.
The laser is customized for distributed fiber optic temperature measurement applications and features high stability, adjustable pulse width and high peak power output at 1550 nm with a minimum pulse width of 5 ns. It supports both ACC and APC mode operation.
BPD570 Series Photodetectors Based on 2 high-performance APD photodetectors with consistent performance, adjustable M-factor, ultra-high common-mode rejection ratio of 30db and low noise.
