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.
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.
This is a 1450/1550/1660nm Raman WDM coupler module for DTS Raman temperature measurement system, with one 1550nm input port and three output ports (1450nm and 1660nm to APD photodetector, COM port to sensing optical cable. This module makes DTS system integration more convenient.
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.
FSW-1×4 multi-mode optical switching module is a device with the role of optical path switching
