Couples twisted (UTP), a form of wiring in which a wire conductor, two to two together have twisted up the electromagnetic disturbances resulting from external sources to neutralize the formation.

in the string, twisted rings, wire, causes the conversion tube, the magnetic signal can be.In stranded wire, balanced, etc., usually two-strand wire signals equal and opposite in a separate data transfer, and in the end combined together.It is these two strands of wire, the amount of electromagnetic disturbances (EMI) similar but with a phase difference of 180 degree are, it would reduce the power of the signal, disturbing the Pointer of the magnetic in this compound.

UTP cable is one of the most common cable used in telecommunication networks and computer.
six types of UTP cable different there that can be used according to the type of network and desired goals of their use . CAT5 cable, etc. the most common type of UTP cable should be considered.
