ETC FU427SDF

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.
