Baseband cabling is defined by which standards according to the material?

• A. IEEE 802.3 and ISO/IEC 11801
• B. ITU-T G.652 and ANSI/TIA 568-C
• C. IEC 60332 and ISO 14763
• D. ANSI/TIA 5682-d and ISO11801-1

Answer: (D)

Baseband cabling is the copper twisted-pair cabling used to carry digital signals in LANs, and the standards that define how this cabling is designed, installed, and tested come from the structured cabling families: ANSI/TIA 568 (and its updates) and ISO/IEC 11801. These standards specify the cabling system architecture, category ratings (like Cat 5e, Cat 6, Cat 6A, etc.), horizontal and backbone cabling arrangements, connectors, termination schemes, performance requirements, and testing methods. The option that lists ANSI/TIA 568 (in the form shown) and ISO/IEC 11801 aligns with the material’s reference to the standards that define baseband copper cabling. Other choices point to fiber standards, Ethernet protocols, or installation references that aren’t the primary baseband cabling standards.
