Abstract
An optical fiber cable includes a core that includes optical fibers, a sheath that accommodates the core, and an interposed layer disposed between the core and the sheath. The interposed layer includes sheet materials arranged in a circumferential direction of the optical fiber to cover the core. Each of the sheet materials includes fibers solidified by a matrix.
Claims20
An optical fiber cable comprising:
- a core that includes optical fibers;
- a sheath that accommodates the core;
- an interposed layer disposed between the core and the sheath;
- and
- a ripcord disposed between the interposed layer and the sheath, wherein
- the interposed layer includes sheet materials arranged in a circumferential direction of the optical fiber cable to cover the core,
- each of the sheet materials includes fibers solidified by a matrix,
- the ripcord is disposed radially outside the sheet material, and at least a part of the ripcord is embedded in the sheath, and
- the sheet materials extend linearly along a longitudinal direction of the optical fiber cable and are disposed parallel to the core.
