Wear resistance high-strength optical cable

Abstract

The invention discloses a wear resistance high-strength optical cable which comprises an outer sheath (1), an anti-interference layer (8) arranged in the outer sheath (1), a support piece arranged in the anti-interference layer (8), an inner sheath (4) arranged between the outer sheath (1) and the support piece, a plurality of fiber protection sleeve tubes (5) arranged in the inner sheath (4), fibers arranged in the fiber protection sleeve tubes (5), and a lubricating layer (9) which is arranged between the outer sheath (1) and the anti-interference layer (8) and is filled with a lubricant. The wear resistance high-strength optical cable has the advantages that through arranging the support piece in the outer sheath, the role of support is played, the anti-compression and bending-resistant ability of the optical cable are improved, the mechanical strength of the optical cable is improved, through arranging the anti-interference layer, the interference of fiber transmission data by an external signal can be shielded, and the anti-torsion ability of the optical cable can be improved through arranging the lubricating layer.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to a wear-resistant high-strength optical cable. Background technique [0002] Optical fiber, referred to as optical fiber, is a light transmission tool that transmits light on the principle of total reflection in fibers made of glass or plastic. The tiny fiber is encapsulated in a plastic sheath that allows it to be bent without breaking. Typically, a transmitting device at one end of the fiber uses a light-emitting diode or a laser to transmit light pulses into the fiber, and a receiving device at the other end of the fiber uses a photosensitive component to detect the pulses. Cables that contain optical fibers are called fiber optic cables. Because the transmission loss of light in optical fibers is much lower than that of electricity in wires, and because the main raw material is silicon, which has a huge reserve and is easy to mine, it is cheap, which prompts optical fibers to b...

AI Technical Summary

Problems solved by technology

The optical cable structure currently used is relatively simple. This optical cable is composed of a single-core tight-buffered optical fiber and a sheath layer coated on the surface of the single-core tight-buffered optical fiber. The production process of this optical fiber is relatively simple, and the mechanical properties of the optical fiber are poor. It is easy to cause the optical fiber to be bent or broken during construction or use, which will eventually lead to the interruption of the transmission of the optical signal and seriously affect the long-term stability of the optical fiber transmission characteristics.
