D371-Type Digital Uncooled DFB Laser Module
Data Sheet
January 1999
Description (continued)
The device characteristics listed in this document are
met at 2.0 mW output power. Higher- or lower-power
operation is possible. Under conditions of a fixed pho-
todiode current, the change in optical output is typically
±0.5 dB over an operating temperature range of –40 °C
to +85 °C.
This device incorporates the new Laser 2000 manufac-
turing process developed by the Optoelectronic unit of
Agere Systems Inc. Laser 2000 is a low-cost platform
that targets high-volume manufacturing and tighter
product distributions on all optical subassemblies. The
platform incorporates an advanced optical design that
is produced on a highly automated production line. The
Laser 2000 platform is qualified for the 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 operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
