Appendix B Cabling Guidelines
UTP Cable Type
When installing network cables, the following table shows appropriate cabling
guidelines for 100BASE-TX Fast Ethernet architecture.
Cabling Components: 100BASE-TX
Trunk and Patch Cable
Type:
4-Pair 100
Ω
UTP CAT 5
(only 2 pairs used)
Modular Plug: 8-Pin RJ-45 CAT 5 only
Patch Panel: 8-Pin RJ-45 CAT 5 only
Table B-1 Network Cable Guidelines
(NOTE: All UTP cables come in both solid and stranded filament. Solid
filament cables are more rigid and usually intended for trunk cabling.
Stranded filament cables are more pliable and generally targeted for patch
cables. For proper termination, use the correct RJ-45 connector, as they
differ for each type of cable.)
UTP Cable Wiring
UTP cables are wired based on one of two standard pin configurations:
Straight-Through and Crossover. 100BASE-TX uses only Category-5 UTP
cables with four pairs of wire as illustrated below in Tables B-2 and B-3.
"Straight-Through" "Cross-Over”
Configuration Configuration
Pin Number Pin Number Pin Number Pin Number
1 (TRX+) 1 (TRX+) 1 (TRX+) 3 (RCV+)
2 (TRX-) 2 (TRX-) 2 (TRX-) 6 (RCV-)
