Easy-to-branch optical cable with high anti-jamming capability

Abstract

The invention discloses an easy-to-branch optical cable with high anti-jamming capability. The optical cable comprises an outer sheath (1), a fireproof layer (7) arranged in the outer sheath (1), a supporting piece arranged in the fireproof layer (7), an inner sheath (4) arranged between the outer sheath (1) and the supporting piece, a plurality of optical fiber protection sleeves (5) arranged in the inner sheath (4) and optical fibers (6) arranged in the optical fiber protection sleeves (5). The optical cable has the advantages that since the supporting piece is arranged in the outer sheath, the optical cable is easy to branch, a supporting effect can also be achieved, the pressure resistance and bending resistance of the optical cable are improved, and the mechanical strength of the optical cable is improved; through the arrangement of the fireproof layer, the optical cable has good fireproof performance, so that the optical cable is protected against damage caused by high temperature; the fireproof layer made of the AFR / 12 material has good heat insulating performance, the internal structure of the optical cable can be protected against high temperature damage, and therefore use safety of the optical cable is ensured.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to an easily branched optical cable with strong anti-interference ability. 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 p...

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.
