High mechanical strength optical cable

Abstract

The invention discloses a high mechanical strength optical cable which comprises an outer sheath (1), an inner support member arranged in the outer sheath (1), an inner sheath (4) arranged between the outer sheath (1) and the support member, a plurality of fiber protection casings (5) arranged in the inner sheath (4), and fibers arranged in the fiber protection casings (5). The outer side of the inner sheath (4) is provided with an armored layer. The high mechanical strength optical cable has the advantages that through arranging the support member in the outer sheath, the sheath is divided with multiple areas to facilitate the installation of multiple groups of cables, thus the cable is easy to be branched, a role of support can be played, the anti-pressing and anti-bending ability of the cable are improved, the mechanical strength of the cable is raised, through arranging the armored layer, the prevention of the deformation of the inner sheath to press the fibers is facilitated, thus the effect of protecting the fibers is achieved, and the anti-pressing ability of the cable can be improved.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to an optical cable with high mechanical strength. 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...

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.
