Indoor/outdoor non-metal optical cable for optical fiber jumper

Abstract

The present invention relates to an optical cable for connecting the indoor/outdoor optical device. The optical cable includes 2-4 sub-units, and each sub-unit is a single-core cable 07 or a filling unit 08. The single-core cable 07 includes a single-core optical fiber 01, a tight tube layer 02, a reinforcing piece 04, and a sub-unit protective layer 03. The filling unit 08 includes a reinforcing piece 04 and a sub-unit protective layer 03. The sub-unit is protected in the middle of an outer protective layer 06. The present invention is used to connect the outdoor optical device and the indoor optical device; has the advantages of high transmission capacity, fast speed, and excellent security; is yielding, flame-resisting, thunder-preventing, and portable; is an indoor/outdoor dual purpose optical cable for the 3G optical network construction.

Description

technical field [0001] The invention relates to a connecting optical cable suitable for indoor / outdoor optical equipment. It is especially suitable for the connection between indoor optical equipment and outdoor optical equipment. It is an indoor / outdoor dual-purpose optical cable for 3G optical network construction. Background technique [0002] With the practical application of 3G technology, the use of optical cables to connect outdoor transmission equipment has become a requirement at this stage. Ordinary indoor optical cables can only meet the requirements for indoor use. The ability of lateral pressure resistance, tensile strength and ultraviolet resistance of optical cables None of them can meet the outdoor requirements, and ordinary outdoor optical cables have the disadvantages that they cannot be directly used as connectors, are not lightning-proof, and are not easy to bend. The following problems exist in the use of conventional optical cables: [0003] 1. Ordina...

AI Technical Summary

Problems solved by technology

[0003] 1. Ordinary optical cables cannot be used as connectors on optical fibers, and must be fused to pigtails to achieve connection with optical equipment, which increases the loss of fusion on the line;

[0004] 2. Ordinary optical cables are mostly armored with metal reinforcements and metal tapes, and they need to be grounded when they are introduced into the room, which can easily lead lightning into the room and cause equipment damage;

[0005] 3. Ordinary optical cables have high hardness and are not easy to bend and lay, so it is necessary to set up a larger-sized cable rack;

[0006] 4. The amount of ordinary optical cable materials is uneconomical, and compared with the indoor / outdoor non-metallic optical jumper optical cables with the same number of cores, it occupies a larger space;

[0007] 5. Ordinary optical cables use polyethylene as the outer sheath. When burning occurs, the flame is easy to spread rapidly along the optical cable, and releases thick smoke and poisonous gas;

[0008] 6. Ordinary optical cables can only be used indoors, and outdoor ultraviolet rays will cause damage and cracking of the optical cable sheath;
