Abstract
The utility model discloses a photoelectric composite data cable comprising a sheath and a cable core wrapped in the sheath. The cable core comprises an optical cable disposed at the center of the sheath and even data cables which are wrapped round the optical cable and which are twisted together. Every two data cables in the twisted data cables form a twisted-pair group used for data transmission. By performing reasonable pitch adjustment on the twisted-pair groups, requirements of voice transmission and data transmission can be satisfied simultaneously and bandwidth can be elevated so that more value-added services can be developed. And what's more, the optical cable is used as the axis of the twisting so that the optical fiber in the optical cable is effectively prevented from being damaged by external force such as stretching or the like. In addition, cost is reduced and construction cost and network construction cost are reduced.
Description
Technical field
The utility model relates to a kind of photoelectricity complex data cable.
Background technology
Wire Access Network in the market comprises: based on the ADSL technology of twisted wire group, based on the Cable Modem technology of HFC net (optical fiber and coaxial cable hybrid network), based on Ethernet access technique and the optical fiber access technology of category-5 cable.Existing twisted wire group copper network is in large scale, and wide coverage is China's the most general present communication access net pattern, and its infrastructure construction is substantially perfect.Yet, along with the develop rapidly of economy, the improving constantly of people's goods and materials lives and the level of cultural life, people no longer only rest in the speech business the exchange of information, but requirement has the interchange of the integrated digital business such as image, data, HDTV (High-Definition Television).Therefore, what the past had spent huge sums and dropped into constitutes main cable access technology with twisted-pair feeder and more and more can not satisfy the user to the needs of broadband services, so that becomes communication networks nowadays to the bottleneck of Development of Information Highway.
Application number is that 200910206146.0 Chinese patent discloses a kind of layer stranded optical/electrical composite cable, this composite rope is made of sheath and cable core, cable core comprises the reinforcement that is positioned at the sheath center, the intertwist body that centers on the stranded optical cable of reinforcement and data cable formation, can satisfy simultaneously voice transfer and transfer of data, and then satisfy the needs of user to broadband services.This layer-twisted type structure of this composite rope, be that the center is reinforcement, optical cable and data cable are stranded around reinforcement, solve cable and opened the inconvenient problem of stripping, but because take reinforcement as stranded center, increased undoubtedly the cable cost, the also corresponding increase of client's operating expenses and networking expense.
The utility model content
The purpose of this utility model provides under a kind of prerequisite that satisfies at the same time voice transfer and transfer of data, so that the photoelectricity complex data cable that production cost also can reduce.
The utility model adopts following technical scheme: a kind of photoelectricity complex data cable, comprise sheath and be coated on the interior cable core of sheath, described cable core comprises the optical cable that is arranged on the sheath center and the even number single data cable that twists together around this optical cable, and the in twos data cable in the described stranded data cable consists of one group of twisted-pair feeder twisted wire group that is used for transfer of data in pairs.
Described twisted-pair feeder twisted wire group is non-shielding twisted wire group.
Described optical cable adopts the tightly packaged fiber of single core.
Described data cable has four, and the two single data cables that radial symmetric distributes form one group of twisted-pair feeder twisted wire group.
Adopt the photoelectricity complex data cable of said structure; because cable core comprises the optical cable that is arranged on the sheath center and the even number single data cable that twists together around this optical cable; data cable consists of one group of twisted-pair feeder twisted wire group that is used for transfer of data in pairs in twos simultaneously; by twisted-pair feeder twisted wire group is carried out rational pitch adjustment; can satisfy simultaneously voice transfer and transfer of data needs; and lifting bandwidth; carry out more value-added service; the more important thing is; because take optical cable as stranded center line; the not external force damage such as Tensile of the optical fiber of effectively having protected optical cable has reduced cost, operating expenses simultaneously; the networking expense is also low.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model.
Embodiment
The embodiment of the utility model photoelectricity complex data cable: as shown in Figure 1, the cross section of this photoelectricity complex data cable is rounded, comprises sheath 1 and cable core, and sheath 1 is made by the PVC material, and cable core is coated in the sheath 1.Cable core consists of by optical cable 3 with around the four single data cables 2 that optical cable 3 twists together, and wherein, optical cable 3 is optical communication element, and to satisfy voice transmission capabilities, optical cable 3 adopts the tightly packaged fiber of single core, is arranged on the center of sheath 1; Every single data cable 2 is made of copper core and the insulating barrier that is coated on copper core periphery, the two single data cables that radial symmetric in the four single data cables distributes consist of one group of twisted-pair feeder twisted wire group in twos, two groups of twisted-pair feeder twisted wire groups are digital communication unit, satisfying data-transformation facility, and every group of twisted-pair feeder twisted wire group is non-shielding twisted wire group.
The process characteristic of above-described embodiment is: the stranded employing two groups of twisted-pair feeder twisted wires group of cable core and flat the dragging of optical cable form, and sheath coating employing extrudes one deck PVC protective cover material and forms.Whole cable has superior bending property and good side withstand voltage properties, by the pitch adjustment to twisted-pair feeder twisted wire group, satisfies the indexs such as the decay of signal transmission and loss, can satisfy simultaneously voice transfer and transfer of data, and production cost is also low simultaneously.
That whole design realizes optical fiber and copper core and deposit, and the communication function that guarantees them all obtains good realization, communication performance meets 5 classes among the YD/T1019-2001 " digital communication with solid polyolefin insulation horizontal twisted pair cable ", surpasses the regulation of 5 classes and 6 class feature requirement indices, take into account simultaneously fiber-optic communications traffic, its optic fibre characteristic index satisfies the regulation of indices among the YD/T 1997-2009 " Access Network butterfly leading in cable ", the communications requirement of satisfying that Fiber to the home.
In above-described embodiment, for satisfying the purpose that in use copper media data and voice transfer realize simultaneously and the principle of considering to save cost, cable core adopts the tightly packaged fiber of two groups of twisted-pair feeder twisted wire groups and single core when product design, namely can satisfy voice transfer, can satisfy transfer of data again, and to twisted-pair feeder twisted wire group is carried out rational pitch design, satisfy circuit to the technical requirement of digital communication unit.In other embodiments, twisted-pair feeder twisted wire group also can be three groups or more groups, and the core number of optical fiber can be selected two or more according to the communications demand.
