2.4 Cable Standards
2.4.1 UTP Cable
UTP cable is classified into the 3 types according to the following standards.
▶
With or without Shield: 3 Types (UTP, FTP, STP)
▶
Used - frequency Band: 7 Categories (Category 1 ~ Category 7)
▶
Inflammable Grade: 4 Grades (CMX, CM, CMR, CMP)
1) Kinds of Cables with or without Shield
Classification Details Use
UTP(or U.UTP) Unshielded Cables for High Speed – Signals
Maximum 200MHz
Voice +Information (Data)+ Low grade Video Signal
FTP(or S.UTP)
1 Layer Shield, Cable Core only shielded
* Shield Materials: AL/Plastic Complex Foil
Or Copper Braid
Maximum 100MHz
Electro Magnetic Interference (EMI) and Electric Stability
is considered
Voice + Information (Data) + Low grade Video Signal
STP(or S.STP)
Dual - shielded Construction, Pair Shielded Cables or
Core Shielded Cables
* Pair - shielded Materials : AL/Plastic Complex Foil
* Core - shielded Materials : AL/Plastic Complex Foil or
Copper Braid
Maximum 500MHz
Voice + Information (Data)+ Video Signal
An Alternative to
75Ω – Coaxial Cable
Notice
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)
Instead of Solid Conductors, Stranded Conductors may be used for the purpose of improving the Flexibility of a UTP
4Pair Cable. The materials and sizes of strands used are regulated in accordance with UL444, and representative sizes
and materials are Un-coated AWG 24 (7/0203A).
In other words, diameter of unshielded wire is 0.203mm and wires are stranded in 1+6 structure. The materials are
annealed coopers.
