What is the 15th pair in a 25 pair cable?

There are 2 types such as: 1- UTP (unshielded twisted pair) is most commonly used in LAN's with maximum cable length of 100m.2- STP (shielded twisted pair)- is extensively used for telephones

There are mainly three advantages: 1] less cost2]data transfer rate is 100 mbps3]it can support more length.

A twisted pair cable consists of two copper conductors, each one with its own plastic insulation and twisted together.

UTP-Unshielded Twisted Pair. Normally UTP contains 8 wires or 4 pair. 100 meter maximum length. 4-100 Mbps speed. STP-Shielded twisted pair. 100 meter maximum length. 16-155 Mbps speed. Lower...
