Description
(continued)
The device characteristics listed in this document are
met at 1.0 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
to +85
°
C.

This device incorporates the new laser 2000 manufac-
turing process from the Optoelectronic Products unit of
Lucent Technologies Microelectronics Group. 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 Lucent’s
highly automated production lines. The laser 2000 plat-
form is qualified for the central office and uncontrolled
environments, and can be used for applications requir-
ing 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.
* Rating varies with temperature.
