srp00244x srp00245x description data sheet 3 2001-12-01 description the infineon optical receiver module has been designed for use in optical networks and is suitable for bit rates up to max. 2.5 gbit/s if used without any tia. the optical receiver module uses a high-speed pin photodetector optional coupled with a hybrid low noise transimpedance amplifier (pin-tia). the optical receiver photodiode can be used for 1310 nm or 1550 nm optical communications. the pin photodiode is made of ingaas/inp and has an active diameter of 75 m. the function of the pin and pin-tia optical recei ver module is to detect input optical power, to transduce the incident radiation into current (pin) and then to convert the current into a voltage (pin-tia). the low input noise current density of the used transimpedance amplifiers in pin-tia?s provides the optical receiver module, when used with appropriate filtering, with ample sensitivity for realizing minimum input power requirements. designers of optical receivers can use the module in any application that benefits from integration of the photodiode and tia into a to coaxial package. typical for such applications are receivers for digital crossconnects, digital loop carriers, add/drop-multiplexers and optical network units. last but not least the fast switching times, low dark currents and the packaging in a compact and hermetically sealed to46 make the optical receivers usable in many other fiber optic receiver applications. one applicatio n is the use in a compact realization of a transceiver in one module like the so called bidi ?
