| MITSUBISHI (OPTICAL DEVICES) FU-427SDF 1.3 mm DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL DESCRIPTION Mod ule type FU-427SDF has been developed for coupling a sin glemode optical fib er and a 1.3 mm wavelength InGaAsP DFB LD (Laser diode). FU-427SDF is suitable to light source for highspeed short haul and long haul digital optical communication systems. FEATURES MQW-DFB laser diode module High-speed response Emission wavelength is in 1.3 mm band APPLICATION High -speed short haul and long haul digital optical communication systems.
