The distributed fiber optic DAS integrated module has a high performance 3k narrow linewidth laser, AOM acousto-optic modulator, EDFA amplifier and other devices integrated inside, with coherent detection optical path and very sensitive technical features.Easy OEM for customers.
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.
The module is internally integrated with a DVS optical path for distributed fiber vibration and a data acquisition card with Gigabit Ethernet interface output, which only needs to be paired with a PC to form a DVS system.
