P171-Type PIN/Preamp November 2000
Description
The P171-type mini-DIL PIN/preamp consists of a PIN
coupled to a multimode fiber pigtail and a wideband linear preamplifier. The PIN incorporated is a rear-illuminated planar diode structure with a low-capacitance
active area for maximum responsivity and speed.
This device incorporates the new laser 2000 manufacturing process from the Optoelectronics Products unit
of Agere Systems Inc. Laser 2000 is a low-cost platform that targets high-volume manufacturing and tight
product distributions on all optical subassemblies. This
platform incorporates an advanced optical design that
is produced on highly automated production 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 absolute 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.
