Short description of the 10BaseT and 100BaseT cable types
Twisted-pair copper cable for star topologies, where the distance between two devices may not exceed 100
meters.
UTP
Unshielded twisted pair
This type of cable belongs to category 3, and is not recommended for use in an industrial environment.
S/UTP
Screened/unshielded twisted pair (screened with copper braid)
Has an overall shield of copper braid to reduce influence of external interference. This cable is
recommended for use with Bus Couplers.
FTP
Foiled shielded twisted pair (screened with aluminum foil)
This cable has an overall shield of laminated aluminum and plastic foil.
S/FTP
Screened/foiled-shielded twisted pair (screened with copper braid and aluminum foil)
Has a laminated aluminum screen with a copper braid on top. Such cables can provide up to 70 dB reduction
in interference power.
STP
Shielded twisted pair
Describes a cable with an outer screen, without defining the nature of the screen any more closely.
S/STP
Screened/shielded twisted pair (wires are individually screened)
This identification refers to a cable with a shield for each of the two wires as well as an overall shield.
ITP
Industrial Twisted-Pair
The structure is similar to that of S/STP, but, in contrast to S/STP, it has only one pair of conductors.
