Abstract
Official abstract text for this publication.
An optical fiber cable of the present disclosure includes: a cable main body including a plurality of optical fibers, each of the plurality of optical fibers including: a plurality of core portions; a cable sheath inside which the plurality of optical fibers are housed; and at least one tensile strength member embedded in the cable sheath; and a connecting member provided at a first end portion of the cable main body.
First claim
Opening claim text (preview).
What is claimed is: 1 . An optical fiber cable comprising: a cable main body comprising a plurality of optical fibers, each of the plurality of optical fibers comprising: a plurality of core portions; a cable sheath inside which 5 the plurality of optical fibers are housed; and at least one tensile strength member embedded in the cable sheath; and a first connecting member provided at a first end portion of the cable main body. 2 . The optical fiber cable according to claim 1 , wherein at least a part of the cable main body is curled. 3 . The optical fiber cable according to claim 2 , wherein a curl outer diameter of the cable main body that is curled is 50 mm or greater and 300 mm or less. 4 . The optical fiber cable according to claim 1 , wherein the first connecting member is a multi-core connector. 5 . The optical fiber cable according to claim 1 , wherein the further comprising a second connecting member is connected to a second end portion of the cable main body. 6 . The optical fiber cable according to claim 5 , wherein one of the first connecting member and the second connecting member is a convertor configured to convert and connect the plurality of optical fibers, each of the plurality of optical fibers comprising the plurality of core portions, to optical fibers, each of the optical fibers comprising a single-core portion. 7 . The optical fiber cable according to claim 1 , wherein the optical fiber cable is configured to be pneumatically fed within a duct.
