Product information "FCI-H125G-10 Si Photodiode-Amplifier Hybrid"

850 nm Band Optimized; Active Area 0.05 mm2; AA Dia. 0.25 mm; Responsivity 3,000 V/W; Transimpedance 8,300 Ω; Package TO-46

OSI Optoelectronics’ silicon photodiode-amplifier hybrid FCI-H125G-10 combines a low noise, high bandwidth photodetector with a transimpedance amplifier designed for short wavelength (850nm) high speed fiber optic data communications.

The FCI-H125G-10 hybrid incorporates a high sensitivity silicon photodetector with a sensing area of 250 µm in diameter. It also includes a high gain transimpedance amplifier producing a differential output voltage for latching to post amplifiers used in electro-optical receivers and transceivers for Gigabit Ethernet and Fiber Channel applications up to 1.25 Gbps over multi mode fiber. The photodetector converts the light into an electrical signal while the output voltage increases with light in/out. This is achieved by a single +3.3 to +5 V positive power supply.

The FCI-H125G-10 hybrid is available in 4-pin TO-46 metal packages with either a double-sided anti-reflective coated window cap or an integrated lens cap. The 250 µm diameter sensing area eases fiber alignment for connectorizing or receptacle attachment. Furthermore, the proximity of the transimpedance amplifier to the photodetector lowers the capacitance associated with long traces, therefore allowing higher bandwidth and sensitivity.

Key Features:

  • Silicon Photodetector / Low-noise Transimpedance Amplifier Hybrid
  • Large Active Area of 250 µm Dia.
  • High Bandwidth / Wide Dynamic Range
  • Automatic Gain Control (AGC)
  • Hermetically Sealed TO-46 Can
  • Single +3.3 to +5 V Power Supply
  • Differential Output

Applications: High Speed Optical Communications; Gigabit Ethernet; Fibre Channel
