There are two ways to use the network cable, one is a cross line and the other is a parallel line The method of crossover cable is: one end adopts 568A standard, and the other end adopts 568B standard The practice of parallel lines is: both ends are 568A standard or 568B standard, (generally used are 568B parallel lines) 568A standard: green-white, green, orange-white, blue, blue-white, orange, brown-white, brown 568B standard: orange-white, orange, green-white, blue, blue-white, green, brown-white, brown You can notice that the difference between the two approaches is that the orange and green are swapped. If the two sides of the connection are not equal, use a parallel cable, such as connecting a computer to a router or switch If the two connected devices are equal, use a crossover cable, such as computer to computer Features: Suitable for 10/100 BASE-TX Ethernet data transmission rate 10/100Mbps, used for 100M network access, interconnection of 100M network equipment, such as 100M switches and 100M switches, PCs with 100M network cards Interconnection with 100M switch PC to PC, PC to ADSL (modem), PC to HUB (hub) PC to Fibercom (optical fiber) Can also be connected to a notebook network card Modular strain relief device: overmolded with PVC, not easy to break, durable and ensure error-free data transmission Smooth and protective lug design: strong flexibility, effectively protect the RJ45 crystal head lugs from being damaged by impact, easy to plug and unplug 50-micron gold-plated copper contacts are used for the five-category network cable crystal head: provide good conductivity and no data loss Twisted pair of data wires (impedance matching): Minimize the cross-talk of data line signals and ensure high-speed error-free data transmission Elastic PVC jacket: flexible and not easy to break, durable
