Cat 4 Cable

It was often used on 16mbps token ring networks.

Cat 4 cable.

A category 4 cable cat 4 cable is a type of twisted pair cable used mainly in telecommunication networks and some computer networks. It was defined in the ansi eia tia 568 and iso iec 11801 specifications. Supports gigabit ethernet but. A cat 4 cable has a variant in unshielded utp and shielded twisted pair stp cables but utp is the primary version.

For a brief period it was used for some token ring 10base t and 100base t4 networks but was quickly superseded by category 5 cable it is no longer common or used in new. Category 4 cable cat 4 is a cable that consists of four unshielded twisted pair utp copper wires supporting signals up to 20 mhz. Cat 6 supports 10 gigabit ethernet only up to 164 feet of cable length. With a 600mhz bandwidth and speeds of up to 10gbps the cat 7 cable is perfect for use in datacenters server rooms telecommunications rooms and large enterprise networks.

However it can be used for networks carrying frequencies up to 20 mhz. Afaik completely obsolete though if you have it you could run plain old telephones over it. Cat 6 cables support higher bandwidths than cat 5. Useless for modern ethernet.

Cat 5 is also used to carry other signals such as telephony and video. This is the network cable that is widely used for 100base t and 1000base t networks as it provides performance to allow data at. Cat 7 26awg ethernet patch cable is designed for cat 7 26awg ethernet patch cable is designed for superior performance in applications utilizing 10 gigabit ethernet. It is used in telephone networks which can transmit voice and data up to 16 mbit s.

Cat 5e is currently the most commonly used cable mainly due to its low production cost and support for speeds faster than cat 5 cables. This cable is not recognised by the tia eia. This is not recognised by the tia eia.
