Data Cable Separation Distance from Source of Interference
Unshielded data cables should not be installed near sources of electromagnetism.
IA/TIA-569, the cabling pathways standard for data cables, specifies these minimum separation distances for structured data cabling systems
with a power source of 480V or less.
