TZ7-00-358C (2/6) MITSUBISHI (OPTICAL DEVICES) FU-675PDF-V2MxxA WAVELENGTH MONITOR INTEGRATED 1.55 µm DFB-LD MODULE WITH POLARIZATION MAINTAINING FIBER PIGTAIL (WAVELENGTH SELECTED, DIGITAL APPLICATION) DESCRIPTION Module type FU-675PDF-V2MxxA is a wavelength monitor integrated 1.55µm 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 can be prepared in accordance with ITU-T recommendation wavelength channel plan for Dense-WDM transmission. FEATURES l Multi quantum wells (MQW) DFB Laser Diode module l Emission wavelength is in 1.55µm band l Polarization maintaining optical fiber pig-tail l Built-in optical isolator l Built-in thermal electric cooler l Butterfly package l With 2 photodiodes for wavelength monitor and optical output power monitor APPLICATION High speed transmission systems (~10Gb/s) Dense-WDM systems ABSOLUTE MAXIMUM RATINGS (Tld=Tset) Parameter Symbol Conditions Rating Unit Laser diode Optical output Pf CW 24 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) °C Operating case temperature Tc -20 ~ 70 °C Storage temperature Tstg -40 ~ 70 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.
