Description
The P172-type receiver consists of a PIN or APD cou-
pled to a single-mode or multimode fiber pigtail and a
linear preamplifier. Both the PIN and APD are rear-illu-
minated planar diode structures with a low-capacitance
active area for maximum responsivity and speed.
This device incorporates the new Laser 2000 manufac-
turing process from the Optoelectronics Products unit
of Agere Systems Inc. Laser 2000 is a low-cost plat-
form that targets high-volume manufacturing and tight
product distributions on all optical subassemblies. This
platform incorporates an advanced optical design that
is produced on Agere Systems’ highly automated pro-
duction lines. The Laser 2000 platform is qualified for
central office and uncontrolled environments, and can
be used for applications requiring high performance
and low cost.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
