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 receiver 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 application is the use in a Compact realization of a
transceiver in one module like the so called BIDI
(
