FCI-H125G-010: A low noise, high bandwidth photodetector plus transimpedance amplifier designed for short wavelength (850nm) high speed fiber optic data communications. 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 electro-optical 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 in/out. 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 connectorixation 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.
