MITSUBISHI (OPTICAL DEVICES) FU-68SDF-V810MxxB 1.55 mm DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL (WAVELENGTH SELECTED, BIAS CIRCUIT INTEGRATED, DIGITAL APPLICATION) DESCRIPTION Mod ule type FU-68SDF-V810MxxB is a 1.55mm DFBLD module with single-mode optical fiber. Th is module is suitable to a directly modulated light source for use in 2.5Gb/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 Multi qu antum wells (MQW) DFB Laser Diode module Input impedance is 25W Emission wavelength is in 1.55mm band High-speed response Built-in optical isolator Built-in thermal electric cooler Butterfly package With photodiode for optical output monitor APPLICATION High speed transmission systems (~2.5Gb/s) Dense-WDM systems ABSOLUTE MAXIMUM RATINGS (Tld=Tset) Parameter Symbol Laser diode Optical output Pf power Forward current If Reverse voltage Vrl Photodiode Reverse voltage Vrd Forward current Ifd ThermoCooler current Ipe electric co oler Cooler voltage Vpe (Note) Operating case temperature Tc Storage temperature Tstg Conditions CW Rating 15 Unit mW CW 150 2 20 2 1.3 3.1 mA V V mA A V -20 ~ 70 °C -40 ~ 85 °C No te) E ven if the thermo-electric cooler (TEC) is operated within the rated conditions, uncontrolled current loading or o peration without heatsink may easily damage the module by exceeding the storage temperature range. Th ermistor resistance sho uld be properly monitored by the feedback circuit during TEC operation to avoid the catastrophic damage.
