Abstract
Provided is an optical fiber cable that is easier to be laid and enables higher-density packaging than an existing cable. This optical fiber cable is a slotless type optical fiber cable including: an optical unit formed by collecting and twisting a plurality of optical fibers or ribbons each formed by arranging the plurality of optical fibers; a cable core housing the optical unit; and a cable jacket provided around the cable core, and a tension member made of a fiber body within the cable core.
Claims7
A slotless type optical fiber cable, comprising:
- an optical unit formed by collecting and twisting a plurality of ribbon in which a plurality of optical fibers are arranged;
- a cable core that accommodates the optical unit;
- a cable jacket provided around the cable core;
- and
- a tension member made of a fiber body in the cable core,
- wherein the optical unit is formed of the ribbon, and
