This page has been written to simply explain what the Cat 5 Network Cable is and the different ways you can use it.

There are a number of different categories of ethernet cables, one of which is the RJ-45 Cat 5 cable.

The Cat-5 cable is short for Category 5 cable, a current industry standard for network and telephone wiring.



Specifications of the Cat 5 Ethernet Cable

Cat-5 cabling supports frequencies of up to 100 Mhz and speeds of up to 100 Mbps (megabytes per second). The Cat-5 Cable is unsheilded wire containing four pairs of 24-gauge twisted copper pairs, terminating in an RJ-45 jack.

Cat5 and Cat5e LAN cables are easily the most popular and the most common, so it is very probable that if you are using an Ethernet cable it is a Cat 5 cable.

However, for the majority Cat5e cables are the normality, as these have fixed a few little issues that came along with the Cat5 cable. Cat5e cables also support the faster speeds of 1000Mbit (or Gigabit) connections.

For more specific information on the Cat5 Cable go to Wikipedia.

Uses for Cat 5 Cables

Cat-5 network cables can be used for 100Base-T & 10Base-T networking, as well as voice cabling, ATM and token ring.

There are two types of Cat5 cables. One of them is a cross-over cable that is used to connect two devices directly to eachother, eg. a PC directly to another PC or a Hub to another Hub.

However, the majority of Cat5 cables are straight through cables, and these are used to connect computers to hubs and switches. You can read more about this on the computer network cable page.
