Abstract

The utility model provides a surpass five types of inside plants includes eight copper conductors, all covering of copper conductor has the insulating layer, the copper conductor twists for two liang and twists the line line, fourth line, third hank line, second hank forming first hank. First hank is 21.5 0.5mm to the lay of line, the second hank is 13 0.5mm to the lay of line. Third hank is 17.5 0.5mm to the lay of line, the fourth hank is 14.5 0.5mm to the lay of line. Foretell surpass five types of inside plants's first hank is adjusted the lay of line, fourth hank line, third hank line, second hank, and through the test, signal attenuation reduces after the adjustment, and propagation velocity accelerates. The reinforcing of adjusted surpass five types of inside plants signal propagation performance.

Description

Surpass five class inside plants

Technical field

The utility model is related to a kind of cable, more particularly to one kind surpasses five class inside plants.

Background technology

With the fast development and the continuous improvement of computing power of network technology, people are to comprehensive wiring system performance More and more higher, the also more and more higher of the requirement to cable performance parameter are required, but the competition of each manufacturer is also more and more fierce, How to ensure that the performance indications for farthest improving and improving product on the premise of manufacturing cost is minimum are particularly important ；The especially problem of the decay of signal, the use feeling of the user of impact.

Utility model content

Based on this, it is necessary to provide it is a kind of avoid problem of signal attenuation surpass five class inside plants.

What the utility model was provided surpasses five class inside plants, including eight copper conductors, and the copper conductor is covered with insulation Layer, the copper conductor is twisted two-by-two to be twisted to line, the 3rd and line, the 4th is twisted to line to forming the first strand to line, the second strand, described First twists the lay to line for 21.5 ± 0.5mm, and described second twists the lay to line for 13 ± 0.5mm, and the described 3rd twists to line Lay be 17.5 ± 0.5mm, the described 4th to twist to the lay of line be 14.5 ± 0.5mm.

It is also right to line, the 3rd strand to line, the second strand including parcel first strand is provided with wherein in one embodiment The tear rope of line, the 4th strand to line.

Wherein in one embodiment, also including being provided with the serving that coats the tear rope.

Wherein in one embodiment, also including first chamber, second chamber, the 3rd chamber, the 4th chamber.First twists right Line, second twist that line, the 3rd are twisted to twist line, the 4th and first chamber, second chamber, the 3rd chamber, the 4th chamber are respectively arranged on to line It is indoor.

Above-mentioned the first strand for surpassing five class inside plants is twisted to line, second and twists the strand twisted to line, the 4th to line to line, the 3rd Away from being adjusted, through test after adjustment, signal attenuation is reduced, and spread speed is accelerated.Surpass five class inside plants letter after adjustment Number propagation performance strengthens.

Description of the drawings

Fig. 1 is to illustrate surpass five class inside plant cross-sectional structure schematic diagrames described in embodiment.

Specific embodiment

For the ease of understanding the utility model, the utility model is more fully retouched below with reference to relevant drawings State.Better embodiment of the present utility model is given in accompanying drawing.But, the utility model can come in many different forms Realize, however it is not limited to embodiments described herein.On the contrary, the purpose for providing these embodiments is to make to this practicality newly It is more thorough comprehensive that the disclosure of type understands.

Fig. 1 is referred to, surpasses five class inside plants including eight copper conductors.The copper conductor is covered with insulating barrier.It is described Copper conductor is twisted two-by-two to be twisted to the strand of line 110, second to the strand of line the 120, the 3rd to the strand of line the 130, the 4th to line to forming first 140.Described first twists the lay to line 110 for 21.5 ± 0.5mm.Described second twists the lay to line 120 for 13 ± 0.5mm. Described 3rd twists the lay to line 130 for 17.5 ± 0.5mm.Described 4th twists the lay to line 140 for 14.5 ± 0.5mm.

Surpassing five class inside plants also includes that being provided with parcel described first twists right to the strand of line the 120, the 3rd to the strand of line 110, second Line the 130, the 4th twists the tear rope 200 to line 140.

Surpassing five class inside plants also includes being provided with the serving 300 for coating the tear rope 200.

Surpassing five class inside plants also includes first chamber 410, second chamber 420, the 3rd chamber 430, the 4th chamber 440. First strand twists that line the 120, the 3rd is twisted to twist line the 130, the 4th to line 110, second and is respectively arranged on first chamber to line 140 410th, in second chamber 420, the 3rd chamber 430, the 4th chamber 440.

Following table is the test performance figure for surpassing five class inside plants, wherein described first twists and is set to blueness to line, described second Strand is set to orange to line, and the described 3rd twists and be set to green to line, and the described 4th twists and be set to brown to line.And surpass five classes with existing Inside plant is contrasted.

As can be seen that the physical length after lay adjustment has shortened, spread speed is accelerated, near from the contrast of Tables 1 and 2 Substantially improve in the parameters such as end cross-talk, FEXT, near-end crosstalk power and FEXT power and surpass five class inside plants Performance.

The performance parameter figure for surpassing five class inside plants before the change of table 1

The performance parameter figure for surpassing five class inside plants after the change of table 2

Embodiment described above only expresses several embodiments of the present utility model, and its description is more concrete and detailed, But therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that common for this area For technical staff, without departing from the concept of the premise utility, some deformations and improvement can also be made, these all belong to In protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be defined by claims.
