Raman pump modules (RPM) Erbium-doped fiber amplifiers (EDFA)
Description
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 performance 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 grating 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, quantum-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 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.
Offering superior wavelength stability, the 269-type pump laser module with fiber grating is designed as a continuouswave (CW) optical pump source for erbium-doped fiber amplifiers and Raman pump modules.

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 k, capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM ESD withstand voltage established for the 269-type laser pump module is ±500 V.

269-Type 14xx nm Pump Laser Module with Fiber Grating 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 module 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.
* A positive input into this pin cools the laser.
