FU-632SEA-3MxxA/FU-632SEA-6MxxA
1.55 mm EAM/DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL(WDM)
DESCRIPTION Mod ule type FU-632SEA-6MxxA is an electroaborption modulator integrated with 1.55mm DFB-LD module with single mode optical fiber. Th is module is suitable to a light source in 2.5Gb/s digital optical communication systems where the distance is shorter than 640km. Th is module is pre pared in accordance with ITU-T reco mmend ation wavelength channel plan for DenseWDM transmission. FEATURES Input impedance is 50W Integrated Electroabsorption Modulator(EAM) Distributed feedback (DFB) Laser Diode Emission wavelength is the 1.55mm band Single-mode optical fiber pig-tail Built-in optical isolator Built-in thermal electric cooler Butterfly package APPLICATION 2.5Gbps,6400ps/nm WDM application 2.5Gbps,12800ps/nm WDM application

No te 1. Even if the thermoelectric cooler(TEC) is operated within the rated conditions, uncontrolled current loading or operation without heat sink 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.
