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.
Claims20
An optical cable comprising:
- a core including at least one optical unit with a plurality of optical fibers;
- a jacket surrounding the core;
- a 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 jacket 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 millimeters (mm) or more, and
- a minimum thickness (tn) of the jacket at the position at which the 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,
- an inflection point is formed at an inner upper end of the jacket stripping channel, and the inflection point is located inside a line connecting the outer circumferential surface of the jacket in a region where the identification means is not formed,
- a width of a cross section of the jacket stripping channel constantly decreases in a radial direction from a center of the optical cable, and
- the width of the cross section of the jacket stripping channel decreases non-linearly.

An optical cable comprising:
- a jacket;
- an optical unit accommodated in the jacket and including a plurality of optical fibers;
- a jacket stripping channel provided as an empty space, which is in the form of a groove with round corners, on an inner circumferential surface of the jacket;
- a ripcord provided on the jacket stripping channel;
- and
- an identification means provided on an outer circumferential surface of the jacket to identify a position at which the jacket stripping channel is formed,
- wherein a maximum height (h) of the jacket stripping channel is greater than an outer diameter of the ripcord;
- and
- wherein the ripcord is continuously accommodated in the jacket stripping channel in a longitudinal direction,
- wherein an inflection point is formed at an inner upper end of the jacket stripping channel, and the inflection point is located inside a line connecting the outer circumferential surface of the jacket in a region where the identification means is not formed,
- wherein a width of a cross section of the jacket stripping channel constantly decreases in a radial direction from a center of the optical cable, and
- wherein the width of the cross section of the jacket stripping channel decreases non-linearly.
9 more elements
An optical cable comprising:
- a core including an optical unit with a plurality of optical fibers;
- a jacket surrounding the core, the jacket defining a 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, outside the jacket, a position at which the jacket stripping channel is formed inside the jacket,
- wherein:
- the jacket stripping channel defines a groove on an inner circumferential surface of the jacket via a first rounded corner of the inner circumferential surface of the jacket that meets at an inflection point with a second rounded corner of the inner circumferential surface of the jacket,
- the inflection point is located inside a line connecting the outer circumferential surface of the jacket in a region where the identification means is not formed, and
- a distance between the first rounded corner and the second rounded corner constantly and non-linearly decreases until reaching the inflection point.
