Pin 6 TEC (+), Pin 7 TEC (-)

Applying a positive voltage on pin 6 with respect to pin 7 will cause the internal submount to be cooled relative to the case

temperature. Reversing the polarity will raise the submount temperature relative to the case. The TEC supply should be capable of

delivering up to 0.9A at 2.4V.

Pin 8, 9, 11, 13 Case ground

These pins must be grounded in all applications

Pin 10

This pin is not connected and should be grounded if possible

Pin 12 Laser modulation (-)

The data input (modulation current) is applied via this pin which is a nominal 25

impedance coplanar line. For 10mW applications

the end of life modulation current is 90mA maximum. For all other applications 60mA maximum modulation current should be

provisioned.

Pin 14 N/C

This pin is not connected. It should be grounded if possible.
