NEC Minimum Separation Distances Between Power and Data Cables
Fiber optic cables transmit data using pulses of light, making them entirely immune to electromagnetic interference. Consequently, fiber optic cables do not require the same minimum separation distances
Interpretation
There is currently a 12 in separation midspan from the fiber optic communications cable and the power company neutral. Rule 235C2b(1)(a) for midspan clearances is relied upon, which states, “For
