D571-Type Digital 1.5 µm Uncooled DFB
FastLight Laser Module
Advance Data Sheet
April 2000
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
Lucent Technologies Microelectronics Group. 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 environ-
ments, 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.
