Product overview
100BaseT
Twisted pair cable for 100 Mbaud. It is necessary to use a higher cable quality and to employ appropriate
hubs or switches in order to achieve the higher data rate.
10BaseF
The 10BaseF standard describes several optical fiber versions.
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 (shielded 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 (shielded with aluminum foil)
This cable has an outer shield of laminated aluminum and plastic foil.
S/FTP
Screened/foiled shielded twisted-pair (shielded with copper braid and aluminum foil)
Has a laminated aluminum shield 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 overall shielding without further specification of the type of shielding.
S/STP
Screened/shielded twisted-pair (wires are individually shielded)
This identification refers to a cable with a shield for each of the two wires as well as an outer shield.
ITP
Industrial Twisted-Pair
The structure is similar to that of S/STP, but, in contrast to S/STP, it has only two pairs of conductors.
