Rarely used due to cost or lack of need, Cat 7 is a copper cable standard designed to support 10 gigabit ethernet over 100 meters.
Cat 7 Cabling
Category 7 cable or Cat 7 is backwards compatible with Cat 6 and Cat5e ethernet cable, and it performs at frequencies up to 600 MHz.. Cat7 is designed with even more stringent specifications for dealing with cross talk and noise. Shielding has been added to each individual pair to accomplish the superior performance. Cat7 uses both the RJ45 connector as well as GG45 electrical connectors. When termination is done with TERA connectors, Cat7 cable is rated for transmissions above 600 MHz.
