Abstract
An optical cable (1) has at least two optical fibers (2, 3), composed of plastic, which are surrounded by a common sheath (6) made of insulating material. To ensure functional endurance, even with frequent bending, the optical fibers (2, 3) are stranded together with a short length of lay which is smaller than six times the diameter (D) of an optical fiber (2, 3). In addition, at least two layers of high tensile strength fibers (5) composed of insulating material are stranded around the optical fibers (2, 3), which are stranded together.
Claims6
An optical cable having at least two optical fibers composed of plastic, which are surrounded by a common sheath made of insulating material, wherein:
- the optical fibers are stranded together with a short length of lay which is smaller than six times the diameter of one of said optical fibers,
- the optical fibers are stranded together and at least two layers of high tensile strength fibers composed of insulating material are stranded around the optical fibers, and
- the sheath is located over the high tensile strength fibers.
