FCI-H125G-010 Datasheet | OSI

1.25Gbps Silicon Photodetector / Transimpedance Amplifier FCI-H125G-010 is a low noise, high bandwidth photodetector plus transimpedance amplifier designed for short wavelength (850nm) high speed fiber optic data munications. The hybrid incorporates a 250µm diameter large sensing area, high sensitivity silicon photodetector. It also includes a high gain transimpedance amplifier producing a differential output voltage for latching to post amplifiers used in electrooptical receivers and transceivers for Gigabit Ethernet and Fibre Channel applications up to 1.25Gbps over multi-mode fiber. The photodetector converts the light into an electrical signal while the output voltage increases with light input. This is achieved by a single +3.3V to +5V positive power supply. These devices are available in 4 pin TO-46 metal packages with either a double sided AR coated window cap or an integrated lens cap. The 250µm diameter sensing area eases fiber alignment for connectorization 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.
