super five types of cables and six types of cable difference between
"Super five categories "Refers to the super five kinds of unshielded twisted pair (UTP—Unshielded Twisted Pair)
Unshielded twisted-pair cable is made up of much of Twisted Pair and a plastic sheath.Five refers to the international electrical industry association as the twisted-pair cable definition of five different quality levels.
super five kinds of unshielded twisted pair is in part of the performance of existing five types of shielded twisted-pair cable, after improved many performance parameters, such as near end crosstalk crosstalk and attenuation ratio, return loss and so on all have improved, but the transmission bandwidth of 100 MHZ.
super five kinds of twisted pair is used for and 1 the four tensile anchor, the color of the line to the completely same with five kinds of twisted pair, white, orange, orange, white, green, green, white and blue, blue, white, brown, and brown.Bare copper wire diameter is 0.51 mm (24 awg wire gauge), insulated wire diameter is 0.92 mm, UTP cable is 5 mm diameter.Although the super five kind of unshielded twisted pair also can provide up to 1000 MB/s transmission bandwidth, but often rely on the support of the expensive special equipment.So, usually only be applied to 100 MB/s fast Ethernet, realization of desktop switches connected to the computer.If not prepared to later will be upgraded to gigabit Ethernet network, so might as well in a horizontal cabling is made of super five classes of shielded twisted-pair cable.
"Six class "Refers to the six types of shielded twisted-pair cable
six types of parameters in the shielded twisted-pair cable has greatly increased, the bandwidth is expanded to 250 MHZ or higher.Six kind of twisted pair in shape and structure with five classes or super 5 kinds of twisted pair has certain difference, not only increased the cross the skeleton of the insulation, the four pairs of line of twisted pair separately under cross skeleton four grooves, and the diameter of the cable is thicker.
cable cross in the middle of the skeleton with the change of the length and Angle of rotation, the four pairs of twisted-pair cable card within the skeleton of the groove, maintain the relative position of four sets of twisted pair, improve the balance characteristic of cable and crosstalk attenuation.In addition, keep the balance structure of cable in the process of installation is not damaged.Six kinds of unshielded twisted pair copper wire diameter is 0.57 mm (wire gauge for 23 awg), insulated wire diameter is 1.02 mm, UTP cable diameter is 6.53 mm.
super five types of cables and six types of cable which good
depending on the electrical performance of twisted wire can be divided into three categories, five, five, six and seven twisted-pair cable.Different categories of twisted-pair cable price differs even disparity, scope of application are also quite different.
in addition to the traditional voice systems still use three kinds of twisted pair, network cabling is basically in the super class five or six unshielded twisted pair.Five kinds of unshielded twisted pair is still can support 1000 base-t, but because the price is almost the same with super five kinds of unshielded twisted pair, therefore, has gradually faded out wiring market.
six kind of unshielded twisted pair, although the price is higher, but with the ultra five types of cabling system has the very good compatibility, and able to support 1000 base-t is very good, so is slowly become the latest must-haves in the integrated wiring.Seven types of shielded twisted-pair cable because it is a kind of brand-new wiring system, while performance is excellent, but because of the expensive.Construction is complex and can choose the product is less, so rarely used in wiring project.
six types of shielded twisted-pair cable can support gigabit Ethernet is very well, and implement the transmission distance of 100 m.Therefore, six wiring system is widely used server room wiring, and the level of retains the ability to upgrade to gigabit Ethernet cabling.According to the wiring standard ISO 11801, wiring system of life expectancy, at least for 10 years.As a long-term investment, integrated wiring should give full consideration to the development of the network's potential demand and wiring system, therefore, under the condition of capital allows, suggest choose six product building wiring system.
if considering the application requirement of network in the future, in theory should be installed the most advanced cabling products, because after the installation of cable is often difficult to update replacement, basically, a wiring system to apply at least 10 years as a standard, can support 4 to 5 generations of the performance of the network equipment update, if in the future network equipment need to be better cable to improve the speed of data.
then, with six kinds of cable instead of super five type of cable is inevitable, but the cable back to form engineering is very expensive, so even though six product prices relatively in five kinds of products are more expensive, but in order to reduce the network upgrade in the future, six kind of product is still worth considering.
