Description
Technical field
The utility model relates to a kind of information transmission equipment, is specifically related to a kind of cable with buffer unit.
Background technology
Connect local area network (LAN), netting twine is absolutely necessary.Netting twine common in a local network mainly contains twisted-pair feeder, coaxial cable, three kinds, optical cable.Twisted-pair feeder, by many data lines formed line.Its feature is exactly low price, so be widely used, and telephone wire etc. as common in us.It is used to be connected with RJ45 connector.It has again STP and UTP two kinds, and that we commonly use is UTP.
Netting twine, by eight copper conductors, in order to reduce the mutual interference of electromagnetic signal, presses certain density snarl together for every two.Like this, the electric wave that spoke body goes out each other when transmission of electric signals will be cancelled out each other, and effectively eliminates interference.This name of twisted-pair feeder is also extend out because of such structure.In outside, there are one deck toughness and the protection of high protection crust.Twisted-pair feeder use is the earliest used to the transmission of telephone signal, just gradually be incorporated in the middle of the transmission of digital signal afterwards, a long time ago, we are the 3 class twisted-pair feeders used substantially, the maximum bandwidth that can only reach 16Mbps, and we are widely used in a computer network is now all super Category-5 twisted pair and six class twisted-pair feeders.The maximum bandwidth that can reach 1000Mbps.
The unique shortcoming of twisted-pair feeder is exactly that transmission range is shorter, can only reach 100 meters, so when wiring, if use Star-like Analysis-Frame, it is two-way that the scope covered can only reach the transmission of 200*200 rice 1000M network card data, needs use four pairs of lines, i.e. 8 heart yearns.Below 100M, generally uses 1,2,3,6, four lines.Orange, green totally four lines by standard.Wherein 1,3 one group, 2,6 one group 4,5 is siding 7,8 is that telephone wire T568A standard line order is from left to right followed successively by: 1-is green in vain, 2-is green, 3-is orange in vain, 4-is blue, 5-is blue in vain, 6-is orange, 7-is brown in vain, 8-is brown.T568B standard line is sequentially from left to right followed successively by: 1-orange is white, 2-is orange, 3-is green in vain, 4-is blue, 5-is blue in vain, 6-is green, 7-is brown in vain, 8-is brown.1 exports data (+), 2 export data (-), 3 inputs data (+), 4 are left phone uses, 5 are left phone uses, 6 inputs data (-), 7 are left phone uses, 8 are left phone uses, the easy flattening deformation of existing netting twine, thus causes Signal transmissions to go wrong or slowed down, simultaneously due to length long, cannot know fast after fracture, crystal head easily loosens and data cube computation loosens, and impact uses.
