Optical Fiber Cable
Abstract:
This optical fiber cable is a central-core-type cable in which slotted rods are not used, and is composed of a core, a wrapper, a tension member, a ripcord, a sheath, and the like. The core is formed by twisting together a plurality of optical fiber units without back-twisting. The optical fiber units are formed by twisting together a plurality of intermittently-fixed optical fiber ribbons. A direction in which the optical fiber ribbons are twisted together is same as a direction in which the optical fiber units are twisted together.
