Description
The Cat5e crossover cable is a type of ethernet cable that is used to connect two devices directly to each other without the need for a switch or hub. Unlike regular ethernet cables, which are wired to connect a computer to a switch or hub, a crossover cable is wired so that the transmit and receive signals are swapped between the two devices. Cat5e crossover cables are commonly used to connect two computers or two switches together, allowing them to communicate with each other without the need for an intermediary device. They can also be used to connect other devices that use ethernet, such as game consoles or printers.
