3M six cable Product Features: Currently, LAN are generally used to unshielded twisted pair category 5 4 pairs (ie, 8 wire) cable. These twisted pair transmission rate can reach 100Mbps. Category 3 twisted thin outer protective rubber on the market, marked marked "Class 3" words, the lower the price of the "CAT3" word, the rubber outer carton; 5 twisted pair thick outer protective rubber , the rubber on the label marked "CAT5" word, packaging cartons of "Category 5" words, the higher the price. Do not purchase cheaper to buy low-quality Category 5 twisted pair, these products are often only as a Category 3 twisted pair to use. Category 5 twisted-pair unshielded twisted pair belongs. Compared with ordinary twisted pair Category 5, Category 5 twisted pair transmission signal attenuation when smaller, stronger anti-interference ability. In the 100M network, the extent of the interference of the user equipment is only 1/4 of the ordinary Category 5 cable is ideal for network applications solutions. "Super-five" means over unshielded twisted pair (UTP-UnshieldedTwistedPair) unshielded twisted-pair cable is more on the twisted pair and a plastic skin composition. Five refers to five different quality levels for the International Electrical Industry Association definition of twisted pair cable. Cable after over unshielded twisted pair is part of the performance improvement of the existing five shielded twisted pair, many performance parameters, such as the near-end crosstalk attenuation crosstalk ratio, return loss, and so have increase, but the bandwidth is still 100MHz. UTP twisted pair is also used for around four and a tensile wire, wire colors and five twisted pair are identical, respectively, white orange, orange, white and green, green, white, blue, blue, white Brown and Brown. Bare copper wire diameter of 0.51mm (AWG for 24AWG), insulation diameter of 0.92mm, UTP cable diameter of 5mm. UTP twisted pair usually only be applied to 100Mb / s Fast Ethernet desktop switches to realize the connection to the computer. If you want to later upgrade to Gigabit Ethernet network, you may wish to employ over unshielded twisted pair cabling level. UTP unshielded twisted pair can provide up to 1000Mb / s of bandwidth, but often need the help to support the high cost of special equipment. Super five or six "six" refers to the parameters of six six unshielded twisted pair unshielded twisted pair has a substantial increase in bandwidth is extended to 250MHz or higher. Six twisted pair in the structure and appearance of five or over five twisted pair has some differences, not only increases the insulation of cross frame, the four twisted pairs of wire were placed in four cross skeleton within a groove, and the diameter of the cable is more coarse. Cable with the center of the cross frame length and the rotation angle variation, the card will be four pairs of grooves in the frame to maintain the relative position of the four twisted pairs, cable-balanced properties and improve crosstalk attenuation. Further, to ensure equilibrium during the installation structure of the cable is not damaged. Six unshielded twisted-pair copper wire bare diameter 0.57mm (AWG for 23AWG), insulation diameter of 1.02mm, UTP cable diameter is 6.53mm. According to different electrical properties, twisted pair can be divided into three, five, over five, six and seven types of twisted pair. The price difference between different types of twisted even larger disparity range of applications is also very different.
