| MITSUBISHI (OPTICAL DEVICES) FU-627SDF 1.55 mm DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL DESCRIPTION Mod ule type FU-627SDF has been developed for coupling a sin glemode optical fib er and a 1.55mm wavelength InGaAsP DFB LD (Laser diode). FU-627SDF is suitable to light source for high-speed short haul digital optical communication systems. FEATURES MQW-DFB laser diode module High-speed response Emission wavelength is in 1.55 mm band APPLICATION High -speed short haul and long haul digital optical communication systems.
