BALANCED TWISTED PARE CABLE QUESTIONS
WITH 100% ACCURATE ANSWERS
Balanced twisted-pair cables have a nominal characteristic impedance of - Accurate answers 100
ohms at 100 MHz
Insulation - Accurate answers Copper wires must be physically separated
UTP - Accurate answers unshielded twisted-pair
screened/shielded cabling offers - Accurate answers a higher immunity to EMI and may be used in
areas susceptible to EMI, possibly eliminating the need for metallic conduit in some environments.

A screened/shielded twisted-pair cable must be terminated in a - Accurate answers 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 - Accurate
answers 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: - Accurate answers • 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)].
