Abstract
The utility model discloses a category 6-+ unshielded data cable comprising twisted pairs (101) and an outer sheath (102) outside the twisted pairs (101). A high-density polyethylene filler (103) with the section in a cross shape is arranged in the center of the cable, the filler (103) is provided with protruded edges (104), and the adjacent edges (104) and a framework (105) of the filler (103) form a cavity to separate the twisted pairs (101). The filler (103) effectively weakens interference of electromagnetic coupling, enables the frequency of a signal to be improved to 550MHz from 250MHz and greatly improves the transmission rate of the data cable.
Description
Technical field
The utility model relates to a kind of data cable, particularly a kind of super-six type unshielded data cable of cross talk resistance energy.
Background technology
Present 5 classes, 6 class data cables are widely used in the Ethernet 10/100/1000BASE-T comprehensive wiring system, even but appoint the demand that does not so satisfy data communication like this, and along with the promulgation of IEEE802.3an 10GBASE-T standard, the 10G wiring technique has been gone down platform finally, is just considered by more and more enterprises and enables.But, also be unusual harshness to the performance requirement of cable itself because the requirement of 10G10GBASE-T system is too high.
Common 6 class data cables in the market can not satisfy the requirement of 10GBASE-T system, if common six classes are used for the 10GBASE-T system, system can not bring into play its function, meeting because crosstalk or losing of packet and cause the data can not normal transmission, system's instability influences the quality level of whole network.Its main cause be because common six class data cables crosstalk and electric property such as return loss can only be tested to 250MHZ, once frequency surpasses 250MHZ, crosstalk and the performance index of return loss will sharply descend, signal to noise ratio worsens, cause the interference between signal to strengthen, can not the normal transmission signal.
The utility model content
Technical problem to be solved in the utility model provides a kind of anti-super-six type unshielded data cable of crosstalking that still can guarantee the data normal transmission under the high frequency state.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of super-six type unshielded data cable, comprise the oversheath that twisted pair wire and twisted pair wire are outer, be provided with the cross section at the center of cable and be " ten " word shape high density polyethylene (HDPE) filler, described filler has outstanding edge, and the cavity that the skeleton of neighboring edge and filler constitutes is separated twisted pair wire.
Be convenient stripping sheath, described oversheath inboard is provided with tears rope.
Utilize frame to fill and promote the performance that cable is crosstalked effectively.Filler is raw material with the high density polyethylene (HDPE), this dielectric material intensity is high and have extraordinary toughness, in the time of twisted pair wire and filler stranding together, filler with twisted pair wire effectively at interval, and the cavity that is constituted by the skeleton of edge and filler wraps in therebetween firmly, can weaken greatly like this line to electromagnetic coupled disturb, can significantly promote the performance of crosstalking.The marginal portion of filler has also increased line to the distance between outer wall, has so also effectively reduced cable itself to the interference of cable on every side.
The utility model cable does not change the production procedure of common six type unshielded data, do not reduce its production efficiency yet, effectively weakened the interference of electromagnetic coupled, can make the frequency of signal rise to 550MHZ, promoted the transmission rate of data cable greatly by 250MHZ.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, a kind of super-six type unshielded data cable, be provided with the cross section at the center of cable and be " ten " word shape high density polyethylene (HDPE) filler 103, described filler 103 has outstanding edge 104, and neighboring edge 104 is separated twisted pair wire 101 with the cavity of skeleton 105 formations of filler 103.
In addition, filler 103 can promote the transmission performance of cable itself, can reduce this cable to the signal interference of cable on every side, effectively promotes the performance that cable is crosstalked.
Behind the stranding, oversheath 102 is extruded becoming on the cable by extruder, will tear rope 106 simultaneously and be arranged on the oversheath inboard.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection range of the present utility model.
Claims (2)
1. super-six type unshielded data cable, comprise the oversheath (102) that twisted pair wire (101) and twisted pair wire (101) are outer, it is characterized in that: be provided with the cross section at the center of cable and be " ten " word shape high density polyethylene (HDPE) filler (103), described filler (103) has outstanding edge (104), and neighboring edge (104) is separated twisted pair wire (101) with the cavity of skeleton (105) formation of filler (103).
2. super-six type unshielded data cable according to claim 1 is characterized in that: be provided with in described oversheath (102) inboard and tear rope (106).
