Q

What are the wiring requirements for the two horizontal cabling runs?

A
  • One four-pair 100 Ω UTP
  • A second four-pair 24 AWG 100 Ω UTP, two-pair 150 Ω STP, or two-strand, 62.5/125 μm hybrid cables meeting TIA-568-C standard
  • Coaxial cable (allowed but not part of a compliant system)

UTP stands for Unshielded Twisted Pair, STP stands for Shielded Twisted Pair.

Q

What are some considerations for planning work area cabling?

A
  • Patch cords designed for easy routing changes
  • Patch cords with the same connectors on both ends
  • Copper patch cords constructed with stranded cable for flexibility
  • Maximum horizontal cable length assumes a patch cord length of 3 m (10 ft.)
  • Each work area should have two telecommunications outlets/connectors installed
