Ethernet cable basics:

 
  The Ethernet cables for connectivity in most office and home environments rely on twisted wire pairs within an overall cable - Cat 5, Cat 6 and Cat 7 all used this format. Twisting the wires together enables the currents to balance, i.e in one wire the current is moving in one direction, and int he other wire of the pair the current is going in the other, enabling the overall fields around the twisted pair to cancel.

In this way, data can be transmitted over considerable lengths without the need for undue precautions.

As several twisted pairs are contained within a particular network cable, the number of twisted per unit length is arranged to be different for each pair - the rate being based on prime numbers so that no two twists ever align. This reduces crosstalk within the cable.

The Ethernet cables are available in a variety of lengths as patch cables, or the cable itself is available for incorporating into systems, buildings, etc. The terminations can then be made to the required connector using a crimp tool. These network cables are available in a variety of lengths - long Ethernet cables are available, some of the longest being up to 75 metres.

Earlier network cables were unshielded, but later ones were shielded to improve the performance. For example an unshielded twisted pair (UTP) cable may be satisfactory for a short run between a computer and router, but a foil shielded cable, FTP, is best longer runs or where the cable passes through areas of high electrical noise.
