Advance Data Sheet

P172-Type Receiver

August 2001

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.
