Abstract
An optical fiber ribbon includes a plurality of colored single fibers that are arranged side by side, and the adjacent single fibers are coupled by coupling resin. The single fibers are disposed leaving a gap between the single fibers. The adjacent single fibers are bonded to each other intermittently by coupling parts at predetermined intervals in a longitudinal direction. That is, the coupling parts between the adjacent single fibers are disposed intermittently with regard to the longitudinal direction of the single fibers. The coupling parts are formed of opaque coupling resin. A haze value of the coupling resin according to JIS K 7136 is preferably between 1.5% and 3%, for example.
Claims4
An optical fiber ribbon comprising:
- a plurality of single fibers that are arranged side by side, wherein the single fibers that are adjacent to each other are coupled with coupling resin;
- coupling parts between the adjacent single fibers are disposed intermittently with regard to a longitudinal direction of the single fibers;
- the coupling resin is opaque;
- a haze value of the coupling resin according to JIS K 7136 established on Feb. 20, 2000, by Japanese Industrial Standards Committee is between 1.5% and 3%;
- and
- each of the single fibers has a colored coating layer, and a haze value of the colored coating layer measured according to JIS K 7136 is 90% or more.
