Abstract

The utility model discloses a data network and an optical fiber combination cable. The optical fiber combination cable comprises four twist pair groups, each twist pair group is formed by mutually twisting two alloy conductors wrapped with insulation layers and wrapping polyurethane film strips on the two alloy conductors, the cross-shaped support frame is formed by subjecting thermoplastic elastomers to an extrusion molding, the four twist pair groups are distributed in four regions of the support frame, an optical fiber bundle sleeved with a loose tube is respectively arranged in each region form a cable cores, and the exterior of the cable core is sequentially wrapped with a shielding layer, a fire-proofing layer and a sheath layer. The data network and the optical fiber combination cable have the advantages that the structural design is reasonable, by means of the support frame, the four twist pair groups are separated, simultaneously the optical fiber bundles are added, optical signals and electric energy can be simultaneously transmitted, and the signal transmission is stable and slightly affected by outside and the cable.

Description

A kind of data network and optical fiber combination cable

Technical field:

The utility model relates to cable, relates in particular to a kind of data network and optical fiber combination cable.

Background technology:

Four pairs of traditional unit networks line structure compactedness are poor, and transmission of information is single, and the signal transmission is subjected to the external interference effect, and signal transmission quality is low.

In order to guarantee up to 200MHZ data transfer performance, alloy conductor adopts the solid mild alloy conductor of high conductivity, insulating barrier adopts the polyolefine material of low dielectric constant, two of even structure is thoroughly done away with the edge single line twist together formation pair twist group, gathering for four groups becomes whole piece data-signal transmission link again.

The utility model content:

In order to remedy the defective of prior art problem, the purpose of this utility model provides a kind of data network and optical fiber combination cable, reasonable in design, and signal transmission quality is good, is subjected to extraneous impact with self very little.

The technical solution of the utility model is as follows:

Data network and optical fiber combination cable, it is characterized in that: comprise four groups of pair twist groups, every group of mutually stranded and wrapped polyurethane film band formation of alloy conductor that the pair twist group adopts two wrap insulate layers, there is thermoplastic elastomer (TPE) to be extruded into criss-cross bracing frame, four groups of pair twist groups are distributed in the regional of bracing frame, the fiber bundle that also is provided with the loose sleeve pipe of suit in the regional consists of cable core jointly, and cable core is enclosed with successively outward and is enclosed with successively screen, fireprotection layer, restrictive coating.

Described data network and optical fiber combination cable is characterized in that: described screen adopts proof copper-wire braided to consist of, and count is not less than 90%.

The utility model has the advantages that:

The utility model reasonable in design by bracing frame is cut open four groups of pair twist components, is set up fiber bundle simultaneously, transmits when realizing light signal and electric energy, and stable signal transmission is subjected to the external world and self affects little.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

Embodiment:

Referring to Fig. 1:

Data network and optical fiber combination cable, comprise four groups of pair twist groups, every group of pair twist group adopts the alloy conductor 1 mutually stranded and wrapped polyurethane film band 3 of two wrap insulate layers 2 to consist of, there is thermoplastic elastomer (TPE) to be extruded into criss-cross bracing frame 4, four groups of pair twist groups are distributed in the regional of bracing frame 4, also be provided with the fiber bundle 6 common formation cable cores of the loose sleeve pipe 5 of suit in the regional, cable core is enclosed with successively outward and is enclosed with successively screen 7, fireprotection layer 8, restrictive coating 9.

Screen 7 adopts proof copper-wire braided to consist of, and count is not less than 90%.
