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 ABSOLUTE MAXIMUM RATINGS Parameter Laser diode Photodiode fib er (Tld=25° C) Symbol Forword current If Reverse voltage Vrl Reverse voltage Vrd Conditions Rating Unit CW 800 mA - 2 V - 20 V for monitoring Forward current Ifd - 2 mA Cooler Voltage Vpem - 4.5 V (Note) Current Ipem - 1.8 A Operating case temperature Tc - -20~+65 °C Storage temperature Tstg - -40~+70 °C 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.
