Balanced twisted-pair cables have a nominal characteristic impedance of - ✔✔-100 ohms at 100 MHz
Insulation - ✔✔-Copper wires must be physically separated
UTP - ✔✔-unshielded twisted-pair
screened/shielded cabling offers - ✔✔-a higher immunity to EMI and may be used in areas susceptible
to EMI, possibly eliminating the need for metallic conduit in some environments.
U/UTP = - ✔✔-Overall unshielded twisted-pair with unshielded twisted-pair
A screened/shielded twisted-pair cable must be terminated in a - ✔✔-a shielded modular connector in
order to optimize the product's transmission performance characteristics.
, Category/class rated cable may be used to support many types of services, including - ✔✔-voice and
data cabling, electronic safety and security systems, building automation systems, audiovisual systems,
and other types of ICT systems.
All category/class rated cables have the following characteristics: - ✔✔-• Composed of insulated
conductors twisted together to form circuit pairs.
• Provide support for noise cancellation techniques through conductor twisting.
• Generally have a characteristic impedance of 100 ohm (± 15 ohm).
• Conductor sizes are 22 AWG [0.64 mm (0.025 in)] to 24 AWG [0.51 mm (0.020 in)].
