Cabling The Cat 5 Cable

The term 'Cat 5 cable' stands for Category 5 cable. It consists of a twisted pair of Ethernet cable and is used for networking. The cable facilitates the high signal integration and may be shielded or unshielded. There are four twisted pairs enclosed in a cable jacket that helps in retaining a signal-to-noise ratio and is therefore not effected by any external interference or by any other twisted pair cable. As a result any crosstalk or leakage of sound is avoided. These cables normally support 100 Mbit/s networks.

The core cable is used to connect the wall socket to the patch panel socket while the stranded cable is used to connect the hub to the patch panel socket or a wall port to a computer. The cable and connector types and cable topologies are defined by telecommunication standards called TIA/EIA-568-B. The connectors used to connect Cat 5 cables are called 8P8C modular connectors or simply RJ-45. There are two pin/pair assignments called T568A and T568B, that define the order of wire connection.

As mentioned earlier, the cable jacket consists of four twisted pairs of cable. The basic pair of cables are blue, orange, green and brown in color for first, second, third and fourth pairs respectively. Each pair consists of two wires, one of a solid color and other one is white with stripes of one of the above mentioned colors.

Wiring

Cat 5 are the uncovered twisted pair cables facilitating the high signal integrity. They have a frequency of 100 Mhz and are normally used for home or small business. They are available as stranded or solid core cables. Solid core cables are normally used to wire a house.

The following are the steps to wire cat 5 cables:

* Expose or strip off a cat 5 cable. * Untwist the pair but not beyond the exposed point. * Arrange the colored wires. * Trim the wires and leave them exposed from the sheath. * Insert the exposed wires into RJ45 end in a proper order and in a manner that the cable sheath extends up to RJ45 end. * Crimp the end with a crimper tool. * Cut the cable according to your needs and try to keep the cable as short as possible. Longer cables normally result into poor speed.

A structured cabling for Cat 5 cabling means to wire a house or an office in a way that facilitates the best communication following certain standards. The best way defined by these standards is to lay the wires in a star manner so that all the cables terminate at a single point or a patch panel.
