Cable Separation Guidelines in Data Centers: Avoiding EMI and
Avoid routing fiber optic cables directly alongside copper cables, as vibrations or weight from copper can stress fiber cables, increasing the risk of macrobending.
Industry standards such as ANSI/TIA-568 and ISO/IEC 11801 provide the following guidelines: Unshielded Power Cables:50 mm (2 inches) for up to 2 kVA power cables. IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating C...
