FU-427SLD-F1
1.3
m
m LD MODULE WITH SINGLEMODE FIBER PIGTAIL
DESCRIPTION
Mod ule type FU-427SLD-F1 has been developed for
coupling a sin glemode optical fib er and a 1.3
m
m wavelength InGaAsP LD (Laser diode).
FU-427SLD-F1 is suitable to light source for high-
speed long haul digital optical communicatio n
systems and measuring instruments.
