Cat6 cables assemblies are a group of cables gathered together in a protective casing, used to connect up computer networks. They are a type of twisted pair cable, usually used as an ethernet connection. They can support 10-gigabit ethernet over distances of up to 55 metres. Cat6 cables are backwards compatible with cat5e and cat5 cable assemblies.
Cat6 cable assemblies are used when the network bandwidth needs to be higher than that supported by cat5 cables. Cat6 can support a bandwidth of up to 250 Mhz, while cat5 only supports 100 Mhz. Where the distance between computers is greater, a cat6 cable may also be used, as cat5 tend to support shorter distances, while cat6 can stretch up to 55 metres.
Cat6 cable assemblies broadly differ in the configuration of their connections, which can be of different types and genders. They can also have different shield types and can be of varying cable lengths.
