Gigabit Ethernet 1000Base-TX Cabling Recommendations
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbit/s Ethernet communications over distances of up
to 100 meters using 4 pairs of CAT-5 (or higher) balanced, unshielded twisted-pair cabling. For wiring guidelines,
system designers and integrators should refer to the Telecommunications Industry Association (TIA) TIA/EIA-568-
A wiring standard for minimum cabling performance specifications required for proper Gigabit Ethernet operation.
