Abstract
The present disclosure relates a multi-core optical cable with a plurality of optical units, in which damage to a core is prevented during the stripping of a jacket for connection or splitting of the optical cable, and the workability of stripping the jacket is improved.
Claims26
An optical cable comprising:
- a core including at least one optical unit with a plurality of optical fibers;
- a jacket surrounding the core;
- at least one jacket stripping channel formed consecutively as an empty space between the jacket and the core in a longitudinal direction of the optical cable;
- and
- an identification means provided continuously in the longitudinal direction on an outer circumferential surface of the jacket to identify a position, at which the jacket stripping channel is formed, outside the jacket,
- wherein the jacket stripping channel is in the form of a groove having round corners and formed on an inner circumferential surface of the jacket, and the empty space of the stripping channel is exposed without causing damage to the core when the jacket is removed along the identification means by a jacket stripping tool,
- a maximum height of the jacket stripping channel is 0.5 mm or more, and
- a minimum thickness (tn) of the jacket at the position at which the at jacket stripping channel is formed is in a range of 20% to 90% of an average thickness of the jacket at which a position at which the jacket stripping channel is not formed.
