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.
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.
