(L-Band) DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL
(WAVELENGTH SELECTED, BIAS CIRCUIT INTEGRATED, DIGITAL APPLICATION)
DESCRIPTION
Module type FU-68SDF-V810MxxB is a 1.58碌m
(L-Band) 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 to expand the wavelength
channels into L-Band for Dense-WDM transmission.

Note) 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.
