Title:
OPTICAL FIBER
Document Type and Number:
WIPO Patent Application WO/2007/080703
Kind Code:
A1
Abstract:
Optical fiber (1) comprising glass fiber (10) including core (11) and cladding
(12); first coating layer (13) of transparent resin with a refractive index lower
than that of the cladding (12), superimposed on the circumferential surface
of the glass fiber (10); and second coating layer (14) of opaque resin superimposed
on the circumferential surface of the first coating layer (13). In first region
(W1) along the length thereof, the first coating layer (13) and second coating
layer (14) are removed to thereby realize exposure of the smooth circumferential
surface of the glass fiber (10). In second region (W2), the second coating layer
(14) is removed to thereby realize sheathing of the glass fiber (10) by the first
coating layer (13). In third region (W3), the first coating layer (13) and second
coating layer (14) sheathe the glass fiber (10). In fourth region (W4) included
in the second region, the first coating layer (13) is provided with scattering
part (13A) capable of light scattering.
