| MITSUBISHI (OPTICAL DEVICES) FU-630SLD-8M1/10M1/12M1 1.48 mm PUMP LD MODULE WITH SINGLEMODE FIBER (EDFA) DESCRIPTION Mitsubishi's FU-630SLD series 1480nm laser diode mod ules are designed as optical pumping sources for erbium-dop ed fib er amp lifier (EDFA).This mod ule is suitable to a light source for use in bi-directional pumped EDFA. FEATURES MQW laser diode mod ule specificaly optimized for pump laser applications Emission wavelength is in 1.48 mm 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 pump amplifier(EDAF) source for erbium-dop ed fib er ABSOLUTE MAXIMUM RATINGS Parameter Laser diode Photodiode for monitoring Cooler (Note) Forword current Reverse voltage Reverse voltage Forward current Voltage Current (Tld=25 C) Symbol If Vrl Vrd Ifd Vpem Ipem Tc Tstg Conditions CW Rating 800 2 20 2 4.5 1.8 -20~+65 -40~+70 Unit mA V V mA V A C C Operating case temperature Storage temperature No te. Evan if the thermo-electric cooler (TEC) is operated within the rate d conditions, uncontrolled current loading or operation without heatsink may easily damage the mod ule by exceeding the storage. Th ermistor resistan ce should be properly mon itored by the feedback circuit during TE C operation to avoid the catastrophic damage.
