Abstract
An optical fiber cable comprises a slender base body having spiral grooves formed on the outer circumferential surface, and at least one optical fiber tape housed within each of said grooves, said tape including a plurality of insulated optical fibers and a resin coating layer covering said optical fibers. The base body is formed of a mixture of at least two materials differing from each other in the molecular weight distribution. The particular construction permits markedly suppressing an increase of transmission loss derived from micro-bend occurring in the optical fiber tape arranged within the base body, and also permits arranging optical fiber tapes within the base body at a higher density.
Claims2
An optical fiber cable, comprising:
- a longitudinally extending core body having spiral grooves formed thereon;
- and
- at least one optical fiber ribbon housed in any one of said grooves, said ribbon including a plurality of optical fibers embedded in a strip of resin,
- wherein said core body is made from a mixture of at least two materials having differing molecular weight distribution.
