when do you use an ethernet crossover cable
Ethernet crossover cable An Ethernet crossover cable is a crossover cable for Ethernet used to connect computing devices together directly. It is most often used to connect two devices of the same type: e.g. two computers (via their network interface controllers) or two switches to each other. By contrast, patch cables or straight through cables are used to connect devices of different types, such as a computer to a network switch or Ethernet hub.
Category 6 cable When used for 10/100/1000BASE-T, the maximum allowed length of a Cat 6 cable is up to 100 meters (328 ft). This consists of 90 meters (295 ft) of solid "horizontal" cabling between the patch panel and the wall jack, plus 5 meters (16 ft) of stranded patch cable between each jack and the attached device.[7] For 10GBASE-T, an unshielded Cat 6 cable should not exceed 55 meters.[8]
