Introduction
1.5.3 Supported Fiber Optic Cables
Follow these recommendations for copper data cabling in high electrical noise envi-
ronments:
• 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 communica-
tions.
• 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.
