269-Type 14xx nm Pump Laser Module
with Fiber Grating
Applications
s Raman pump modules (RPM)
s Erbium-doped fiber amplifiers (EDFA)
Description
Offering superior wavelength stability, the 269-type pump
laser module with fiber grating is designed as a continuous-
wave (CW) optical pump source for erbium-doped fiber ampli-
fiers and Raman pump modules.
Features
s High-coupled rated output power up to 280 mW,
CW
s Available with fiber grating for wavelength stability
(1420 nm—1510 nm)
s Wide environmental range
s Field-proven packaging technology
s InGaAsP/InP high-power, strained multiple quan-
tum-well (MQW) chip design
s Internal thermoelectric cooler (TEC)
s InGaAs PIN photodetector back-facet monitor
s Single-mode and polarization-maintaining fiber pig-
tails
s Compact, 14-pin butterfly package
s Industry compatible package and pinout
The 269-type pump laser module with fiber grating
represents a family of thermoelectrically cooled,
high-power lasers. These modules utilize a fiber
Bragg grating to achieve stable wavelength perfor-
mance within the 1420 nm to 1510 nm range, over
the full operating temperature range. They are
designed as continuous-wave (CW) optical pump
sources for dense wavelength-division multiplexing
(DWDM) EDFA and Raman applications operating in
the C- and L-bands. The 269-type laser modules with
polarization-maintaining fiber are particularly suitable
for use in RPM designs requiring the high-power
combinations of multiple pumps.
The laser optical spectrum is locked by the fiber grat-
ing over a wide optical power range. The optical
spectrum is very narrow and the peak wavelength is
nearly insensitive to temperature variations and back
reflections.
The laser modules incorporate a high-power, quan-
tum-well laser chip that achieves grating-stabilized
fiber powers ranging to 280 mW.
An integral thermoelectric cooler (TEC) stabilizes the
laser at room temperature and, combined with a her-
metic environment, allows the device to achieve
high-power operation over the extended temperature
range of 0 °C to 75 °C. An internal InGaAs PIN pho-
todiode, 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 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 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 eval-
uation. 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 withstand voltage established for the 269-type laser pump module is ±500 V.
