3.3 Cable Standards
3.3.1 UTP Cable
UTP cables are categorized into two types with the following standards..
①
Shield type: Three types (UTP, FTP, STP)
②
Seven types of frequency bands used 7 types (Cat.1-7)
(1) Cable types (shields)
Type Details Purpose
UTP(or U.UTP) Unshielded cable for fast signals
Max 200 MHz
Audio + Data + Low video signals
FTP(or S.UTP) Cable shielding cable cores only
Max 100 MHz
Considers EMI and electric stabilization
Audio + Data + Low video signals
STP(or S.STP)
Double layer shielding by shielding
each pair and
cable shielding cable cores only
Max 500 MHz
Audio + Data +
Video signals
For replacing 75Ω coaxial cables
Note
(1) UTP: Unshielded Twisted Paired Copper Cable
FTP: (Overall) Foiled Twisted Paired Copper Cable
STP: (Overall) Shielded (and Shielded Individually Pair) Twisted Paired Copper Cable
(2) Patch Cable (or Patch Cord)
For the purpose of improving the flexibility of the UTP 4-pair cables, sometimes a wired conductor is used instead
of a solid conductor.
The target standards and materials used are Un-coated AWG 24 (7/0203A).
In other words, the small line diameter is 0.203 mm, the small line is standardized to 1 + 6 structure, and the
material is the annealing copper wire.
(3) For the PLC Ethernet communication cable use of the S.STP cable is recommended. If the S.STP cable
cannot be used due to the environmental conditions, it may result in communication abnormalities and noise in more
than one module.
