| LBRF |
| |
| Low Bending Radius Single Mode Optical Fiber [ LBRF ] |
LBRF is designed to provide improved performance across the
full wavelength region form 1265 to 1625nm and it has low sensitivity to
macrobending results in lower attenuation levels in the 1625 nm region.
LBRF fully meets ITU-T G.652D & G.657 and is available for
use in loose tube cable, ribbon and other cable designs.
Especially, the Low bending performance is useful for FTTH application. |
| FEATURESS BENEFITS |
