Gigabit Ethernet 1000Base-TX Cabling Recommendations 5
Section 1.5.2
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:
Cabling Category
1000Base-
TX Compliant
Required Action
< 5 No New wiring infrastructure required.
5 Yes Verify TIA/EIA-568-A compliance.
5e Yes No action required. New installations should be designed with Category 5e or higher.
6 Yes No action required.
> 6 Yes Connector and wiring standards to be determined.
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.
• Shielded/screened cabling can be used when required. Care should be taken to avoid the creation of ground
loops with shielded cabling.
