1.58 µm (L-Band) DFB-LD MODULE WITH POLARIZATION MAINTAINING FIBER PIGTAIL
(WAVELENGTH SELECTED, BIAS CIRCUIT INTEGRATED, DIGITAL APPLICATION)
DESCRIPTION
Module type FU-68PDF-V520MxxB is a 1.58µm
(L-Band) DFB-LD module with polarization
maintaining optical fiber.
This module is suitable to a CW light source for
external modulator for use in 2.5Gb/s and 10Gb/s
digital optical communication systems.
This module is prepared to expand the wavelength
channels into L-Band for Dense-WDM transmission.
FEATURES
l Multi quantum wells (MQW) DFB Laser Diode
module (100GHz spacing)
l Input impedance is 25
l Emission wavelength is in 1.58µm band
l Polarization maintaining optical fiber pig-tail
l Built-in optical isolator
l Built-in thermal electric cooler
l Butterfly package
l With photodiode for optical output monitor
APPLICATION
High speed transmission systems (~10Gb/s)
Dense-WDM systems
OPTION
l Wavelength option:
1565nm~1625nm are available

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.
