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.
To ensure reliable, error-free data communications, new and pre-existing communication paths should be verified
for TIA/EIA-568-A compliance. The table:
relevant cabling standards as they apply to 100Base-TX connections.

Follow these recommendations for copper data cabling in high electrical noise environments:
• Data cable lengths should be as short as possible, ideally limited to 10' (3 m) 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.
• Optionally, shielded/screened cabling can be used. The cable shield should be grounded at one single point to
avoid the generation of ground loops.
