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 photodetec-
tor 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 µm. 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 transimped-
ance amplifiers in PIN-TIA's provides the optical receiver mod-
ule, 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 ben-
efits from integration of the photodiode and TIA into a TO coax-
ial 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® (Fig. 1).
