Secure digital data systems
Benefits
Easily board mounted
Gull-wing leads
No additional heat sinks required
Low-cost alternative to industry-standard, 14-pin iso-
lated laser module (ILM)
Highly efficient DFB-MQW laser structure allows for
lower threshold and drive currents, and reduced
power consumption
Description
The D572-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 long-
reach (SONET) and other high-speed digital applica-
tions.
The module includes a narrow linewidth (<1 nm) DFB-
MQW single-mode laser and an InGaAs PIN photo-
diode back-facet monitor in a hermetically sealed pack-
age.
This package is optimized for a 25
input impedance
and allows for dc biasing through an internal bias tee.
A thermistor has been included for feedback to board-
level bias circuitry, if needed.

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
photodiode current, the change in optical output is typi-
cally 0.5 dB over an operating temperature range of
0 C to +70 C.
This device incorporates the new Laser 2000 manufac-
turing process from the Optoelectronic Products unit of
TriQuint Semiconductor. Laser 2000 is a low-cost plat-
form that targets high-volume manufacturing and
tighter product distributions on all optical subassem-
blies. This platform incorporates an advanced optical
design that is produced on one of the highly automated
production lines at the Opotelectronic manufacturing
facility. The Laser 2000 platform is qualified for the cen-
tral 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 pe-
riods can adversely affect device reliability.
* Rating varies with temperature.

Handling Precautions
CAUTION: This device is susceptible to damage as a result of electrostatic discharge (ESD). Take proper
precautions during both handling and testing. Follow guidelines such as JEDEC Publication
No. 108-A (Dec. 1988).
TriQuint Semiconductor employs a human-body model (HBM) for ESD-susceptibility testing and protection-design
evaluation. ESD voltage thresholds are dependent on the critical parameters used to define the model. A standard
HBM (resistance = 1.5 k
, capacitance = 100 pF) is widely used and can be used for comparison purposes.
