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 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.
APD20 series APD photodetector module, can detect near infrared light in the region of 400-1700nm with fiber coupling input, bandwidth from 10M to 400M. suitable for detecting nW level of optical power.
The DET30 bias photodetector is a compact, unamplified, fiber-optic input, battery-powered detector with very low noise, and can be used to detect optical signals with ps-level pulse widths.
