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
μ
in. (0.8
μ
m), and the surface flat-
ness must be better than 0.001 in. (25.4
μ
m). 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.
