Introduce Of SSPD InGaAs Photo Detector

The SSPD high-speed Photo Detector is designed for both digital and analog applications. The module contains an InGaAs PIN photodiode in which response wavelength covers 1000 to 1650 nm and necessary matching electronics.

NEON’s SSPD can provide a bandwidth of 20 GHz. The module operates on +5 V. It complies with a standard single-mode 9 / 125 μm fiber input. The RF output port is an SMP-compatible connector matched by 50-ohm impedance.

SSPD is hermetically sealed in a small house and weighs less than 8 grams.

Precautions

  1. The fiber bending radius no less than 20mm for avoiding 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.
