What is the mean of UTP, S/UTP, FTP, STP AND SFTP Cat5e, Cat6, Cat6a Cable?

The content below shows the different types of copper Ethernet cable and gives a brief description of each type. Electromagnetic shielding/screening can be made from a metallic or polyester foil, or metallic braid, either around individual conductor pairs, all 4 pairs, or 2 pairs. Cat5e, Cat6 and Cat6a are available in unshielded and shielded formats, Cat7 is only available as a shielded cable. Mult-strands copper flexible cat 5e, cat 6, cat 6a cable can be used to assemble m12 ethernect cable.

 UTP is short for Unshielded Twisted Pair.

 The UTP cable consists of pairs of wires twisted together. This is one of the most basic methods used to help prevent electromagnetic interference. 

 FTP is short for Foiled Twisted Pair 

 FTP offers an additional layer of protection with shielding (also called screening) wrapped around the individual twisted wires. This protects against EMI/FRI and crosstalk.

 S/UTP & F/UTP is short for Shielded/ Screened or Foiled Unshielded Twisted Pair

 This has an overall foil or braid screen covering the 4 pairs of unshielded twisted pairs.

 S/FTP  is short for Shielded and Foiled Twisted Pair

 A combination of the two above, with foil shielding around the individual twisted wires and an overall screen which can sometimes be a flexible braid.This provides the maximum level of protection from interference and is found in the highest performance cables.
