FU-68PDF-V510MxxB
1.55 mm DFB-LD MODULE WITH POLARIZATION MAINTAINING FIBER PIGTAIL (WAVELENGTH SELECTED, BIAS CIRCUIT INTEGRATED, DIGITAL APPLICATION)
DESCRIPTION Mod ule type FU-68PDF-V510MxxB is a 1.55mm DFBLD module with polarization maintaining optical fiber. Th is module is suitable to a CW light source for external modulator for use in 2.5Gb/s and 10Gb/s digital optical communication systems. Th is module is pre pared in accordance with ITU-T reco mmend ation wavelength channel plan for DenseWDM transmission. FEATURES Input impedance is 25W Multi qu antum wells (MQW) DFB Laser Diode module Emission wavelength is in 1.55mm band Polarization maintaining optical fiber pig-tail Built-in optical isolator Built-in thermal electric cooler Butterfly package With photodiode for optical output monitor APPLICATION High speed transmission systems (~10Gb/s) Dense-WDM systems

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.
