BICSI Installer 2, Copper, Chapter 1, Balanced Twisted Pare Cable (A+ Graded Already).

Balanced twisted-pair cables have a nominal characteristic impedance of correct answers 100 ohms at 100 MHz Insulation correct answers Copper wires must be physically separated UTP correct answers unshielded twisted-pair screened/shielded cabling offers correct 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. F/FTP = correct answers Foil-screened foil-screened twisted-pair F/UTP = correct answers Foil-screened unscreened twisted-pair S/UTP = correct answers Braid-screened unscreened twisted-pair SF/FTP = correct answers Braid-screened-foil-screened foil-screened twisted-pair SF/UTP = correct answers Braid-screened-foil-screened unscreened twisted-pair U/UTP = correct answers Overall unshielded twisted-pair with unshielded twisted-pair A screened/shielded twisted-pair cable must be terminated in a correct 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 correct 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: correct 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)].
