Introduce of AMPD-S Laser Photodetector

The AMPD-S is a laser photodetector integrated by a broadband InGaAs photodiode and low noise amplifier. The response wavelength of the InGaAs PIN photodiode is 1000 to 1650nm. The RF gain of a low-noise amplifier is 15 dB. 

AMPD-S photodiode laser detector can provide the bandwidth of 12GHz and 18GHz. The module operates on +5V supply voltages. It complies with a standard single-mode 9/125μm fiber input. The RF output port is an SMA-compatible connector matched by 50-ohm impedance.

APMD-S is hermetically sealed and weighs less than 23 grams. 

ROHS 2.0 certificated.

Model Information

Model Information


  1. The fiber bending radius is no less than 20 mm to avoid fiber damage.
  2. Be sure the fiber coupling facet is clean before connecting it to Opto-circuit.
  3. Suitable ESD protection is required in storage, transportation, and use.
