FU-68SDF-x9yyMzzF

1.55

μm DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL

DESCRIPTION

Module type FU-68SDF-x902MzzF/-x910MzzF is a

1.55

μm DFB-LD module with single mode optical fiber.

This module is suitable to a directly modulated light

source for use in 2.5Gb/s digital optical communication

systems.

This module is prepared in accordance with ITU-T

recommendation wavelength channel plan for Dense-

WDM transmission.

Note 1) Even if the thermo-electric cooler (TEC) is operated within the rated conditions, uncontrolled current loading or

operation without heatsink may easily damage the module by exceeding the storage temperature range.

Thermistor resistance should be properly monitored by the feedback circuit during TEC operation to avoid the

catastrophic damage.
