Abstract

The utility model discloses a single network cable capable of running two isolated signals. The single network cable is characterized in that a 100M CAT5E RJ45 eight-core cable is adopted as the main line M from an access-layer switch to a desktop; RJ45 sockets are respectively connected with two ends of the main line M, and jumper wire plugs C are respectively inserted into the RJ45 sockets at the two ends; the jumper wire plugs C establish a channel A between a switch I and a PCI through an RJ45 plug A1 according to the TIA/EIA568-B connection standard and establish a channel B between a switch II and a PC1I through an RJ45 plug B1 according to the TIA/EIA568-B connection standard; and the channel A between the switch I and the PCI is physically isolated from the channel B between the switch II and the PC1I.

Description

Can move two-way isolation signals single channel netting twine

Technical field

The utility model relates to the network connectivity structure.

Background technology

For the information security issue of internet, enterprises and institutions adopt the two network operation modes of Intranet and the physically-isolated two-shipper of outer net usually, and the network connection between from the access-layer switch to the desktop computer is because of its One's name is legion, become the difficult points of two nets in building.For newly-built network, can lay the two-way netting twine during comprehensive wiring, realize two net isolation, but transform for the circuit that had only a netting twine originally, adopt two kinds of schemes usually, the one, wireless network, the 2nd, increase new line method of cloth again, but the stability of wireless network and fail safe all can not be protected, and in addition the method for wiring not only workload is big, also can destroy architectural decoration, influence attractive in appearancely, particularly some place concerns because of building structure, is difficult to rewiring.

In the prior art, from the access-layer switch to the desktop, what all adopt usually is to surpass five class RJ45, eight heart yearns, press the wiring of TIA/EIA568-B standard, under 100M speed, in fact only made 1,2,3,6 quads, all the other quads are under the redundant state, be used for phone or other circuit in the reality, or idle, and this form is obviously being deposited unreasonable for the two net systems of two-shipper of needs operation two-way isolation signals.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of two-way isolation signals single channel netting twine that moves being provided, in the stable operation of guarantee network high-speed, and greatly minimizing wiring, thus save cost, simplification installation.

The utility model technical solution problem adopts following technical scheme:

The design feature that the utility model can move two-way isolation signals single channel netting twine is from the access-layer switch to the desktop, eight heart yearns that adopt a 100M, surpass five class RJ45 are basic routing line M, two ends at described basic routing line M connect the RJ45 socket respectively, patch jumper wire plug C respectively in the RJ45 socket of described two ends, described jumper wire plug C sets up the passage A of switch I and PCI by RJ45 connector A1 by TIA/EIA 568-B wiring standard; And set up the channel B of switch II and PC1I by RJ45 connector B1 by TIA/EIA 568-B wiring standard; The mutual physical isolation of channel B of the passage A of described switch I and PCI and switch II and PC1I.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model has carried out sufficient utilization with eight heart yearns of RJ45 in the prior art, makes that the operational mode of the two nets of two-shipper is simplified on the mode of connection greatly, when ensureing network high-speed stable operation, saves cost in a large number, simplifies and install.

2, the utility model utilizes the structure of multiple twin itself to overcome cross-interference issue, passes through positive and negative both direction, big or small identical electric current on a twisted pair wire simultaneously, and the magnetic field effect of generation can be cancelled out each other, thereby has eliminated each to crosstalking mutually between the line.

3, the relative radio network technique of the utility model, the network high-speed of more effective guarantee (100M) stable operation prevents that effectively the disabled user from inserting, and prevents intranet and extranet serial connection accident.

Description of drawings

Fig. 1 is the utility model structural representation.

Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

Embodiment

Referring to Fig. 1, in the present embodiment from the access-layer switch to the desktop, eight heart yearns that adopt a 100M, surpass five class RJ45 are basic routing line M, two ends at described basic routing line M connect the RJ45 socket respectively, patch jumper wire plug C respectively in the RJ45 socket of described two ends, described jumper wire plug C sets up the passage A of switch I and PCI by RJ45 connector A1 by TIA/EIA 568-B wiring standard; And set up the channel B of switch II and PC1I by RJ45 connector B1 by TIA/EIA 568-B wiring standard; The mutual physical isolation of channel B of the passage A of described switch I and PCI and switch II and PC1I.

Experimental situation:

One of FLUKE tester, two of the notebooks of band 100M network interface card, AMP surpasses five class RJ45 twisted-pair feeder 100M.

Experimental procedure:

1, channel B is disconnected, with FLUKE tester test channel A circuit;

2, insert two notebooks at the channel B two ends, wherein ping another, use FLUKE tester test channel A circuit simultaneously;

3, insert two notebooks at the channel B two ends, wherein notebook size using sharing mode to duplicate on another notebook is the file of 1.7G, when duplicating, and usefulness FLUKE tester test channel A circuit;

4, interchange channel A and channel B repeat above three steps;

5, normally connecting the back by TIA/EIA 568-B standard tests with the FLUKE tester;

Test result shows: under the pattern of dividing two circuits, no matter whether transmitting data on a circuit, line loss on another circuit, the variation of crosstalking are about 1～2db, and tested core performance index are in the regime values scope.
