Waterproof tensile optical cable

Abstract

The invention discloses a waterproof tensile optical cable. The waterproof tensile optical cable comprises an outer sheath (1), a waterproof layer (5) and an inner sheath (6) which are sequentially arranged from outside to inside; the inner sheath (6) is internally provided with multiple optical fiber sheaths (3), multiple optical fibers (4) are arranged in the optical fiber sheaths (3), and multiple reinforcing ribs (2) are arranged in the outer sheath (1). The waterproof tensile optical cable has the advantages that the tensile strength of the outer sheath can be improved, the bending resistant capacity of the optical cable is improved when the optical cable is laid in a suspending mode, the deflection of the optical cable can be reduced, large shakes, caused by a strong wind, of the optical cable are avoided, therefore, reduction of abrasion of the optical cable is promoted, the optical cable can be prevented from restoring to the state before bending under the action of elasticity of the optical cable itself, and the laying precision is prevented from being destroyed; due to the fact that the waterproof layer is arranged, the waterproof and damp-proof capacities can be improved, moisture can be effectively prevented from entering the optical cable, damage, caused by dampness, of the optical cable is avoided, and the service life of the optical fiber is prolonged.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to a waterproof tensile 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 be used for...

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.
