    APD-TIA Pigtailed Detector Module - 1.25Gbps or 2.5Gbps

    Model APD-TIA-12/2
    Price:   US$109.00
    Available Options:
    Connector Type:
    Pigtail Fiber:

This photodetector module integrates an InGaAs avalanche photodiode (APD) and a trans-impedance amplifier (TIA) inside a compact optical fiber pigtailed package. It provides photon detection with high bandwidth and high optical sensitivity. This module is ideal for applications in digital optical communication systems.


  • High bit rate, up to 2.7Gbps
  • High responsivity
  • Built-in high speed low noise TIA
  • Single +3.3V power supply for TIA
  • Differential output
  • Proven field reliability
  • High reliable InGaAs APD chip (Telcordia GR-468 compliant)
  • Wide operating temperature range -40~+85 C degree (optional)


  • SONET, Gigabit Ethernet, Fiber Channel
