Detailed explanation-1: -A UTP cable comprises two to four copper wires. UTP systems such as CAT5/CAT-5e/CAT6/CAT-6a use the eight conductor wires, arranged as 4 pairs (one pair = two copper wires). To reduce common mode interference, each pair is twisted along the cable length.
Detailed explanation-2: -Inside a UTP cable is up to four twisted pairs of copper wires, enclosed in a protective plastic cover, with the greater number of pairs corresponding to more bandwidth. The two individual wires in a single pair are twisted around each other, and then the pairs are twisted around each other, as well.
Detailed explanation-3: -Inside the ethernet cable, there are 8 color coded wires. These wires are twisted into 4 pairs of wires, each pair has a common color theme.
Detailed explanation-4: -The first major difference is the gigabit standards require the use of all four pairs (all eight wires), unlike Fast Ethernet which only utilizes two pairs of wires. As a result, in Gigabit Ethernet, all four pairs must be crossed when building a Crossover cable.
