Transmission Media - 4 Summary on What we have studied on last tutorial ? :- Twisted pair cables are cable of wires twisted around each other forms a twisted pair cable to reduce crosstalk. A number of twisted pair wires are placed inside a protective sheath to form a cable. A pair of unshielded wires wound around each other is known as an UTP. An UTP is a pair of copper wires wound by plastic insulators. UTP is cheapest form of cables available for networking purposes. Electronic Industries Association ( EIA), Telecommunications Industries Association ( TIA) and American National Standards Institute ( ANSI ) are the organisation which have defined standards for UTP cabling. CAT 5 defines a cable that can carry data upto 100Mbps. The signalling frequency of this cable is upto 100 MHz. This type of cable is primarily used in today's Networking Environment. CAT 6 d efines a four pair cable that provides and improved performance as comp...
