Break-resistant optical cable

Abstract

The invention relates to a breakage-resistant optical cable, which comprises a reinforcing core, a cable core, a cable core filler, a coated aluminum strip and a polyethylene sheath. The aluminum strip covers the cable core, and the gap between the reinforcing core and the cable core and between the cable core and the coated aluminum strip is filled with cable core fillers, and the polyethylene sheath covers the coated aluminum strip; The core includes an optical fiber, a tube filler and a loose tube. The loose tube covers the optical fiber, and the gap between the fiber and the loose tube is filled with the tube filler; multiple "I" shapes are embedded in the loose tube. The ribs, the roughness of all surfaces of the ribs are <0.4μm. The invention has the advantages of high strength, bending resistance, good tensile resistance, good toughness and long service life, and has very little attenuation in the signal transmission process, and is suitable for long-distance transmission.

Description

technical field [0001] The invention relates to the technical field of optical cable communication, in particular to an anti-break optical cable. Background technique [0002] An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. With the development of informatization, the amount of information transmission has increased rapidly, and optical fiber cables have been widely used. [0003] 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. During construction or use, it is easy to cause the op...

Problems solved by technology

[0003] 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.
