Introduction of HSPD InGaAs Photodetector

The HSPD high-speed detector module is designed for both digital and analog applications. The module contains an InGaAs PIN photodiode whose response wavelength covers 1250 to 1650 nm and necessary matching electronics.

HSPD can provide the bandwidth of 8 GHz, 12 GHz, 18 GHz, 22 GHz, and 30 GHz. The module operates on +3.3 or +5V (depending on the model of HSPD). It complies with a standard single-mode 9/125μm fiber input. The RF output port is an SMA-compatible connector or 2.92 mm connector matched by 50 ohm impedance.

HSPD is hermetically sealed and weighs less than 15 grams.

ROHS 2.0 certificated.

Precautions

  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 the Opto-circuit.
  3. Suitable ESD protection is required in storage, transportation, and use.
