Send data between computers, printers, servers, and switches. Ethernet category standards describe the cable’s performance capabilities. Higher category numbers mean faster speeds, superior data transfer, and better signal strength. Category cables are backward compatible, so you can mix and match, but your speed will only be as fast as the lowest-rated cable.
Unshielded cable is the choice for day-to-day wiring, such as connecting your desktop computer to an ethernet port.
CM and CMR cable prevent the spread of flames down the length of the cable. CMR is more flame resistant than CM cable.
