Power & EMI Issues -
TRA Broadband Guidelines
36
Conditions Minimum Distance
Unshielded power lines or electrical equipment in proximity to
open or nonmetal pathways
610 mm
Unshielded power lines or electrical equipment in proximity to a
grounded metal conduit pathway
305 mm
 Recommended minimum separation distance from possible sources of EMI
exceeding 5KVA as follows:
 For branch circuits less than 5KVA, a minimal separation of 51mm between
telecom cabling and power cabling should be considered.
Note: FO cable do not cause and are not affected by EMI, however two scenarios
to be evaluated with indoor/outdoor cables:
- FO Cable with steel messenger wire (e.g. Sumitomo Electric indoor)
- FO Cable dielectric only (e.g. R&M indoor/outdoor)
