| MITSUBISHI (OPTICAL DEVICES) FU-630SLD-14M2 1.48 m PUMP LD MODULE WITH SINGLEMODE FIBER (EDFA) DESCRIPTION Mitsubishi' FU-630SLD series 1480nm laser diode s modules are designed as optical pumping sources for erbium-doped fiber amplifier (EDFA). This module is suitable for use in bi-directional pumped EDFA. FEATURES * Strain-MQW laser diode module specifically optimized for pump laser applications * Emission wavelength is in 1.48m band * Built-in optical isolator * Built-in thermal electric cooler * Butterfly package * With photodiode for optical output monitor * Diode are hermetically sealed for high reliability APPLICATION Optical pumping source for erbium-doped fiber amplifier(EDFA) ABSOLUTE MAXIMUM RATINGS (Tld=25 C) Parameter Symbol Conditions Rating Unit Forward current If CW 1000 mA Laser diode Reverse voltage Vrl 2 V Reverse voltage Vrd 20 V Photodiode for monitoring Forward current Ifd 3 mA Voltage Vpem 4.5 V Cooler (Note) Current Ipem 1.8 A Operating case temperature Tc -20~+65 C Storage temperature Tstg -40~+70 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. Thermistor resistance should be properly monitored by the feedback circuit during TEC operation to avoid the catastrophic damage.
