15Ft Cat.5e Crossover Cable Gray Wire/Green Boot | An Ethernet crossover cable is a type of Ethernet cable 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 network interface controller) 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. Our cross over patch cable is offered in gray color cable with green color boots in order to distinguish from straight wired patch cable.
