Copper Cable Classifications

The different categories denote the frequency at which the cable will pass or fail at a number of parameter tests. In theory, the higher the frequency, the more data (megabits per second / Mbps) you can transmit. The word Category is often abbreviated as Cat, as we have below.

Category of
Distance achievable  
Cat5eUp to 100MhzSupports GbE (Gigabit Ethernet/1000Mbps) up to 100m
Cat6Up to 250MhzSupports GbE up to 100m
Cat6aUp to 500Mhz Supports 10GbE up to 100m
Cat7Up to 600Mhz Supports 10GbE up to 100m
Cat7aUp to 1000MhzSupports 10GbE up to 100m
