Bicsi Installer 2, Copper, Chapter 1, Balanced Twisted Pare Cable
questions & answers
Balanced twisted-pair cables have a nominal characteristic impedance of - answer 100 ohms at
100 MHz
Insulation - answer Copper wires must be physically separated
UTP - answer unshielded twisted-pair
screened/shielded cabling offers - answer a higher immunity to EMI and may be used in areas
susceptible to EMI, possibly eliminating the need for metallic conduit in some environments.
F/FTP = - answer Foil-screened foil-screened twisted-pair
F/UTP = - answer Foil-screened unscreened twisted-pair
S/UTP = - answer Braid-screened unscreened twisted-pair
SF/FTP = - answer Braid-screened-foil-screened foil-screened twisted-pair
SF/UTP = - answer Braid-screened-foil-screened unscreened twisted-pair
U/UTP = - answer Overall unshielded twisted-pair with unshielded twisted-pair
A screened/shielded twisted-pair cable must be terminated in a - answer 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 - answer
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: - answer • 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)].
