FU-68SDF-22

MITSUBISHI (OPTICAL DEVICES) FU-68SDF-22 1.55 mm DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL (BIAS CIRCUIT INTEGRATED, DIGITAL APPLICATION) DESCRIPTION Mod ule type FU-68SDF-22 is a 1.55mm DFB-LD module with single-mode optical fiber. Th is mod ule is suitable to a light source for use in 2.5Gb/s digital optical communication systems. FEATURES Multi quantum wells (MQW) DFB Laser Diode module Input impedance is 25W Emission wavelength is in 1.55 mm band High-speed response Built-in optical isolator Built-in thermal electric cooler Butterfly package With photodiode for optical output monitor APPLICATION High speed transmission systems (~2.5Gb/s) ABSOLUTE MAXIMUM RATINGS Parameter Laser diode (Tld=25° C) Symbol Pf If Vrl Vrd I fd Vpe Ipe Tc Tstg Conditions CW CW Rating 10 150 2 20 2 2.4 1.2 -20~+65 -40~+70 Unit mW mA V V mA V A °C °C Optical output power from fiber end Forword current Reverse voltage Photodiode for monitoring Cooler (Note) Reverse voltage Forward current Cooler voltage Cooler current Operating case temperature Storage temperature No te. Even 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 temperature range. Th ermistor resistan ce should be properly mon itored by the feedback circuit during TE C operation to avoid the catastrophic damage. .
