Abstract

Official abstract text for this publication.

An optical fiber cable includes a cable core that includes a plurality of optical fibers, a sheath that is provided around the cable core, a reinforcing sheet that is embedded in the sheath, and a tensile strength member that is embedded in the sheath. The reinforcing sheet is disposed such that a gap is formed in a part in a circumferential direction of the cable core. The tensile strength member is disposed such that a part of the tensile strength member overlaps a line segment connecting a first end portion and a second end portion of the reinforcing sheet in the circumferential direction.

First claim

Opening claim text (preview).

What is claimed is: 1 . An optical fiber cable comprising: a cable core that includes a plurality of optical fibers; a sheath that is provided around the cable core; a reinforcing sheet that is embedded in the sheath; and a tensile strength member that is embedded in the sheath, wherein the reinforcing sheet is disposed such that a gap is formed in a part in a circumferential direction of the cable core, and the tensile strength member is disposed such that a part of the tensile strength member overlaps a line segment connecting a first end portion and a second end portion of the reinforcing sheet in the circumferential direction. 2 . The optical fiber cable according to claim 1 , wherein one or a plurality of the tensile strength members are provided, and a total length of diameters of the tensile strength members is larger than a distance of the line segment connecting the first end portion and the second end portion. 3 . The optical fiber cable according to claim 1 , wherein a plurality of the tensile strength members are provided. 4 . The optical fiber cable according to claim 2 , wherein a plurality of the tensile strength members are provided. 5 . The optical fiber cable according to claim 1 , wherein a rip cord is provided between the cable core and the sheath. 6 . The optical fiber cable according to claim 2 , wherein a rip cord is provided between the cable core and the sheath. 7 . The optical fiber cable according to claim 1 , wherein a diameter of the tensile strength member is 1.2 mm or more and 2.4 mm or less. 8 . The optical fiber cable according to claim 2 , wherein a diameter of the tensile strength member is 1.2 mm or more and 2.4 mm or less.
