The A370-Type Uncooled Laser Module consists of a
laser diode coupled to a single-mode fiber pigtail. The
device is available in a standard, 8-pin configuration
(see Figure 1 and/or Table 1) and is ideal for CATV
applications.

The module includes a multiquantum-well Fabry-Perot
(MQW F-P) laser and an InGaAs PIN photodiode back-
facet monitor in an epoxy-free, hermetically sealed
package.

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 °C
to +85 °C.

This device incorporates the new Laser 2000 manufac-
turing process from the Optoelectronics unit of Lucent
Technologies Microelectronics Group. Laser 2000 is a
low-cost platform that targets high-volume manufactur-
ing and tight product distributions on all optical sub-
assemblies. This platform incorporates an advanced
optical design that is produced on the Optoelectronic
unit’s highly automated production lines. The Laser
2000 platform is qualified for the central office and
uncontrolled environments, and can be used for appli-
cations 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.
