    APD-TIA Pigtailed Detector Module - 1.25Gbps, 2.5Gbps or 10Gbps

    Model APD-TIA
    Price:   US$99.00 US$69.90
    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, from 1.25Gbps to 10Gbps
  • 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


Absolute Maximum Ratings


Please note: With the 10Gbps APD-TIA detector, the bandwidth of its APD photodiode is typically at 7GHz, and the detector is tested at sensitivity of -27.5dBm.

Pin Assignment (Bottom View)

Please note above pin allocation is sample only. Special pin allocation can be requested. Refer to the test data sheet attached with each photodiode for its pin allocation.


Ordering Information:


a: Bit Rate of the Photodetector; a=12 for 1.2Gbps; a=25 for 2.5Gbps, a=10G for 10Gbps
b: Fiber type; b=9 for 9/125 SMF; b=50 for 50/125 MMF; etc.
d: Connector Type, d=FA for FC/APC, d=SU for SC/UPC, d=N for no connectors, etc.
