Description
The D2525P family of DFB laser modules is
designed to be used with a lithium niobate external
modulator (see Table 4). The laser module features a
polarization-maintaining fiber (PMF) pigtail, enabling
it to be directly connected to a modulator without the
need of a polarization controller. The PMF maintains
the polarization of the output light to a consistent ori-
entation. This allows the D2525P to be used as a CW
light source for systems requiring extremely low chirp
such as undersea or 10 Gbits/s systems. The module
contains a multiquantum-well (MQW), distributed-
feedback (DFB) laser. This device nominally has an
output power of 10 mW. The wavelength of the laser
can be temperature-tuned for more precise wave-
length selection by adjusting the temperature of the
internal thermoelectric cooler.

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.

Handling Precautions
Power Sequencing
To avoid the possibility of damage to the laser module
from power supply switching transients, follow this
turn-on sequence:
1. All ground connections
2. Most negative supply
3. Most positive supply
4. All remaining connections
Reverse the order for the proper turn-off sequence.
Electrostatic Discharge
CAUTION: This device is susceptible to damage as
a result of electrostatic discharge. Take
proper precautions during both han-
dling and testing. Follow guidelines
such as JEDEC Publication No. 108-A
(Dec. 1988).
Lucent 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, therefore, can be used for comparison pur-
poses. The HBM ESD threshold presented here was
obtained using these circuit parameters:

Mounting Instructions
The minimum fiber bend radius is 1.50 in.
To avoid degradation in performance, mount the mod-
ule on the board as follows:
1. Place the bottom flange of the module on a flat heat
sink at least 0.5 in. x 1.180 in. (12.7 mm x 30 mm) in
size. The surface finish of the heat sink should be
better than 32 µin. (0.8 µm), and the surface flatness
must be better than 0.001 in. (25.4 µm). Using ther-
mal conductive grease is optional; however, thermal
performance can be improved by up to 5% if conduc-
tive grease is applied between the bottom flange and
the heat sink.
2. Mount four #2-56 screws with Fillister heads
(M2-3 mm) at the four screw hole locations (see Out-
line Diagram). The Fillister head diameter must not
exceed 0.140 in. (3.55 mm). Do not apply more than
1 in.-lb. of torque to the screws.
