Mitsubishi Electric Corporation Semiconductor Group FU-427SDF Datasheet
1.3 mm DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL
DESCRIPTION
Module type FU-427SDF has been developed for
coupling a singlemode optical fiber and a 1.3
m
m wavelength InGaAsP DFB LD (Laser diode).
FU-427SDF is suitable to light source for high-
speed short haul and long haul digital optical
communication systems.
