Abstract
The utility model discloses a photoelectric compound wire cable. The photoelectric compound wire cable comprises a jacket made of halogen-free flame retardant polyolefin materials and a cable core which is composed of an optical cable and even pairs of data cables. The optical cable is located in the center of the data cables, the data cables are intertwisted into the cable core by surrounding the optical cable, each data cable is intertwisted by two core wires according to a certain intertwisting pitch, the core wire intertwisting pitches of each pair of data cables are different, and the optical cable is a single-core or two-core tightly-sheathing optical fiber. The photoelectric compound wire cable can meet the requirements of optical fiber communication and common data communication at the same time, and is particularly suitable for comprehensive access of multiple businesses; the optical cable and the data cables are placed in the same cable, so as to save energy resources, reduce cost and be convenient for construction; as the intertwisting pitches of the data cables are different, the electromagnetic field distribution can be changed and the cross talk attenuation performance can be improved; as the optical fiber adopts the tightly-sheathing structure and is placed in the middle of the cable core, the data cables at the periphery can effectively protect the optical fiber from being damaged by external forces such as stretching and the like.
Description
Technical field:
The utility model relates to a kind ofly can satisfy the compound cable of photoelectricity that the optical fiber communication needs can satisfy the normal data communications needs again.
Technical background:
Along with the develop rapidly of communication traffic, the comprehensive access of multiple business is more and more general, and the existing optical cable in some office spaces is introduced has data cable to introduce again.Tradition introducing mode is to lay an optical cable and a single data cable simultaneously, the cost height, and the wasting of resources is big, the construction trouble.
Summary of the invention:
The purpose of this utility model provides and a kind ofly can satisfy the optical fiber communication needs, can satisfy the normal data communications needs again, is particularly suitable for the compound cable of photoelectricity of the comprehensive access of multiple business, and then reduces cost convenient construction.
In order to solve described technical problem, the utility model has adopted a kind of so compound cable, comprises sheath that the halogen-free anti-flaming polyolefin material is made and the cable core that is made of the data cable of optical cable and even-even.Described optical cable is positioned at the center of described data cable, and this data cable is around the stranded cable core that forms of this optical cable.Described data cable is formed according to certain twisting pitch is stranded by two heart yearns, and each is to the heart yearn twisting pitch difference of data cable.
Described optical cable is single core or two core tight tube fibers.
The beneficial effects of the utility model are:
1, the utility model can satisfy optical fiber communication needs and normal data communications needs simultaneously, is particularly suitable for the comprehensive access of multiple business.
2, optical cable and data cable are placed with cable, economize on resources, and reduce the cost convenient construction.
3, the twisting pitch difference of data cable can change electromagnetic field and distribute, and improves the crosstalk attenuation performance.
4, optical fiber adopts tight tube structure, is placed in the middle of the cable core, and peripheral data cable can effectively protect external force such as optical fiber is not stretched to damage.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the structural representation of the compound cable cross section of photoelectricity.
Embodiment:
Embodiment is as shown in Figure 1: the compound cable cross section of photoelectricity is rounded, comprises sheath 6 and cable core 4.Sheath 6 is made by the halogen-free anti-flaming polyolefin material, and suitable indoor and outdoor is laid.Cable core 4 is made of four pairs of general data cables 3 and the single core tight tube fiber 5 (diameter 0.6mm) that is positioned at the center, and data cable is around the stranded stranding of optical fiber.Every pair of data cable 3 is formed according to certain twisting pitch is stranded by two heart yearns.Every heart yearn is made up of a conductor 1 and a coated insulating barrier 2 outside conductor 1; Conductor 1 is made by the oxygen-free copper bar material, and diameter 0.51 ± 0.01mm, insulating barrier 2 make thickness 0.2 ~ 0.23mm by high-density polyethylene material.The twisting pitch difference of every pair of data cable by suitable pitch configuration, reaches the change electromagnetic field and distributes, and improves the purpose of crosstalk attenuation performance.
Claims (2)
