Description
The 269-type pump laser module represents a family
of thermoelectrically cooled, high-power lasers. They
are designed as continuous-wave (CW) optical pump
sources for dense wavelength-division multiplexing
(DWDM) EDFA applications.
The laser modules incorporate a high-power, quantum-well laser chip that achieves fiber powers up to
280 mW.
An integral thermoelectric cooler (TEC) stabilizes the
laser at room temperature and, combined with a hermetic environment, allows the device to achieve
high-power operation over the extended temperature
range of 0 °C to 75 °C. An internal InGaAs PIN photodiode, mounted behind the laser diode, functions
as the laser detector and monitors light emissions
from the rear facet of the laser.
The 269-type module is offered in a 14-pin, hermetic
butterfly package.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Handling Precautions
Electrostatic Discharge
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
EIA
*
Standard
EIA
625.
Agere Systems Inc. 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 kΩ, capacitance = 100 pF) is widely used and, therefore, can be used for comparison pur-
poses. The HBM ESD withstand voltage established for the 269-type laser pump module is ±500 V.

Mounting and Connections
CAUTION: This device is susceptible to damage as
a result of electrostatic discharge.
Proper precautions should be taken
during both handling and testing.
The base of the laser module (see Outline Diagram)
should be maintained at or below 75 °C (maximum)
during operation. Interfaces between the laser module
base and heat sink must be clean, and the use of a
thermal filler may be necessary.
Mounting Instructions
The minimum fiber bend radius is 1.0 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
thermal conductive grease is optional; however,
thermal performance may be improved if conductive
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
Outline 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.
