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 PD610 is a photodetector with amplification circuitry for free-space optical systems. The unit includes a photodiode, transimpedance amplifier, and RF connector packaged in an aluminum housing.
The PD12 is a photodetector with amplification circuitry for use with FC-connected fiber optic cables in optical systems. The device consists of a photodiode, transimpedance amplifier, and RF connector packaged in an aluminum housing.
