Introduction
1.6.2 Gigabit Ethernet 1000Base-TX Cabling Recommendations
1.6.2
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 m (328 ft) using all 4 pairs in category
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 that characterizes minimum cabling
performance specifications required for proper Gigabit Ethernet operation. For
reliable, error-free data communication, new and pre-existing communication paths
should be verified for TIA/EIA-568-A compliance.
The following table summarizes the relevant cabling standards:
Follow these recommendations for copper data cabling in high electrical noise
environments:

Data cable lengths should be as short as possible, preferably 3 m (10
ft) in length. Copper data cables should not be used for inter-building
communications.
Power and data cables should not be run in parallel for long distances, and
should be installed in separate conduits. Power and data cables should intersect
at 90° angles when necessary to reduce inductive coupling.
