Abstract
The present disclosure relates to an optical fiber cable with tensile material between the inner reinforcing projection, and more specifically, to minimize the increase in diameter even when various interior materials for strength reinforcement are built in, thereby ensuring durability. This relates to an optical cable equipped with a tension member between reinforcing protrusions inside the covering, which can be expected to have advantage effects such as reduced manufacturing costs and improving installation workability with a miniaturized structure.
Claims5
An optical cable comprising:
- a core portion including a plurality of optical fiber bundles;
- a covering portion surrounding the core portion, the covering portion having
- (i) a plurality of reinforcing protrusions protruding from an inner surface of the covering portion toward the core portion, the reinforcing protrusions extending along a longitudinal direction of the optical cable, and
- (ii) a plurality of reinforcing grooves each disposed between adjacent reinforcing protrusions;
- a plurality of first tension members, each of the first tension members built into a corresponding one of the reinforcing grooves and extending along the longitudinal direction to correspond to a length of the reinforcing protrusions;
- a second tension member disposed in the covering portion at a position eccentric from the first tension members, the second tension member extending along the longitudinal direction;
- and
- an index protruding from an outer surface of the covering portion and extending along the longitudinal direction, the index being located at a circumferential position corresponding to the second tension member.
