The IEEE 802.3ab Gigabit Ethernet standard defines 1000Mbit/s Ethernet communications over 
distances of up to 100 meters using 4 pairs of 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.  To 
ensure reliable, error-free data communications, new and pre-existing communication paths should 

be verified for TIA/EIA-568-A compliance. Table 7 summarizes cabling standards available today.

In general the following recommendations should be followed for copper data cabling in high 

electrical noise environments: 
 
•  Data cable lengths should be as short as possible, ideally limited to 3m (10ft) 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 ideally 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 optionally be used.  The cable shield should be grounded at 

one single point to avoid the generation of ground loops.
