Abstract
The utility model discloses a double-joint Ethernet twisted-pair jumper, which belongs to the technical field of Ethernet data transmission and solves the problem of excessive network cable jumpers in a cable distribution frame caused by the factor that one cable of the conventional Ethernet jumper only adopts a group of joints. The double-joint Ethernet twisted-pair jumper comprises an eight-core twisted-pair and four RJ45 crystal heads, wherein the eight-core twisted-pair is equally divided into a first-bundle cable and a second-bundle cable; the two ends of the first-bundle cable are respectively connected with one RJ45 crystal head; and the two ends of the second-bundle cable are respectively connected with one RJ45 crystal head. The double-joint Ethernet twisted-pair jumper can serve as an Ethernet jumper.
Description
Technical field
The utility model relates to a kind of twin adapter ethernet twisted pair wire jumper, belongs to the Ethernet data transmission technique field.
Background technology
According to the Fast Ethernet standard IEEE 802.3u (100Base-TX) that generally uses at present, when using the copper cable twisted-pair feeder to transmit, need use the four-core transmission data in the eight core Category-5 twisted pairs.Because the Ethernet interface of equipment is divided into MDI and MDI-X, therefore, the situation that dissimilar interfaces has when docking is used direct-connected cable, and situation about having is again with intersecting cable.The existing Ethernet wire jumper all is that a cable uses a set of joints, is used as a wire jumper and uses.In the machine room of wiring than comparatively dense, a large amount of netting twine wire jumpers can cause in the distributing frame very crowded.For the engineering staff of frequent use netting twine commissioning device, then need get all a direct-connected wire jumper and an intersection wire jumper simultaneously ready, very inconvenient.
The utility model content
The utility model is for a cable that solves the Ethernet wire jumper only uses a set of joints, causes the too much problem of netting twine wire jumper in the distributing frame, and a kind of twin adapter ethernet twisted pair wire jumper is provided.
The said twin adapter ethernet twisted pair of the utility model wire jumper, it comprises eight core twisted-pair feeders, it also comprises four RJ45 connectors,
Said eight core twisted-pair feeders are divided into the first bunch cable and the second bunch cable, and the two ends of the first bunch cable connect a RJ45 connector respectively; The second bunch cable two ends connect a RJ45 connector respectively.
Two bunch cables are divided into following three kinds of modes:
The said first bunch cable and the second bunch cable are direct-connected cable.
The said first bunch cable is direct-connected cable, and the second bunch cable is for intersecting cable.
The said first bunch cable and the second bunch cable are the intersection cable.
The utility model has the advantages that: the described ethernet twisted pair wire jumper of the utility model has two set of joints, and it is used as a wire jumper as two wire jumpers and uses under the situation of only using one eight core twisted-pair feeder.In the wiring space in saving distributing frame, made things convenient for network technology personnel to debug the use of work.
The utility model use under the intensive environment of wiring closet or the network equipment can be practiced thrift half the cable consumption, or the cable space that takies in distributing frame and the wire casing is tapered to original 50%, has greatly practiced thrift cost and wiring space demand.For the network technology personnel of frequent commissioning device, only need carry a netting twine wire jumper can have the function of direct-connected line and cross spider simultaneously.This wire jumper satisfies the Fast Ethernet standard, and the message transmission rate of single group wire jumper can reach 100Mbps.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment one: below in conjunction with Fig. 1 this execution mode is described, the said twin adapter ethernet twisted pair of this execution mode wire jumper, it comprises eight core twisted-pair feeders, it also comprises four RJ45 connectors 2,
Said eight core twisted-pair feeders are divided into the first bunch cable 1-1 and the second bunch cable 1-2, and the two ends of the first bunch cable 1-1 connect a RJ45 connector 2 respectively; The second bunch cable 1-2 two ends connect a RJ45 connector 2 respectively.
The utility model utilizes the Fast Ethernet standard only to use four cores in the eight core twisted-pair feeders, uses common five types or surpasses five types of ethernet twisted pairs and make wire jumper.The two ends of two bunch cables are made two groups of RJ45 connectors 2 respectively, and each crystal head uses four cores.In actual use, can white orange, orange, white green and green four-core be made into a branch of cable, white indigo plant, indigo plant, white palm fibre and brown four-core are made into another bunch cable.Two groups of wire jumpers on the netting twine have so just been formed.When making RJ45 connector 2,, can be made into two direct-connected cables, two intersection cables or a direct-connected and intersection cable according to the difference of line preface standard.The line preface of making can adopt TIA/EIA 568A standard or TIA/EIA 568B standard.The cable of making is that the direct-connected cable or the cable that intersects can use the line preface of 568A or 568B to control according to user's request.
Embodiment two: this execution mode is for to the further specifying of execution mode one, and the said first bunch cable 1-1 and the second bunch cable 1-2 are direct-connected cable.
Embodiment three: this execution mode is for to the further specifying of execution mode one, and the said first bunch cable 1-1 is direct-connected cable, and the second bunch cable 1-2 is for intersecting cable.
Embodiment four: this execution mode is for to the further specifying of execution mode one, and the said first bunch cable 1-1 and the second bunch cable 1-2 are the intersection cable.
