MITSUBISHI (OPTICAL DEVICES) TENTATIVE FU-68SDF-V802MxxxB 1.58 µm (L-Band) DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL (WAVELENGTH SELECTED, BIAS CIRCUIT INTEGRATED, DIGITAL APPLICATION) DESCRIPTION Module type FU-68SDF-V802MxxB is a 1.58µm (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. FEATURES l Multi quantum wells (MQW) DFB Laser Diode module l Input impedance is 25Ω l Emission wavelength is in 1.58µm band l High-speed response 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 (~2.5Gb/s) Dense-WDM systems OPTION l Wavelength option: 1565nm~1625nm are available ABSOLUTE MAXIMUM RATINGS (Tld=Tset) Parameter Symbol Conditions Rating Unit Laser diode Optical output Pf CW 6 mW power Forward current If CW 150 mA Reverse voltage Vrl 2 V Photodiode Reverse voltage Vrd 20 V Forward current Ifd 2 mA ThermoCooler current Ipe 1.3 A electric cooler Cooler voltage Vpe 3.1 V (Note) Operating case temperature Tc -20 ~ 70 ° C Storage temperature Tstg -40 ~ 85 ° C 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.
