General Consideration: It is generally not recommended to run fiber optic cables in the same conduit as electrical power cables. This is due to several potential risks and complications that can arise from such an arrangement. Electrical cables can produce electromagnetic interference (EMI), which can degrade data. I normally see designs that require separate conduits for fiber and power conductors and for planning my work I think this is best. Firstly, for fiber cable in conduit. If they share the same conduit, doesn't that require (per the NESC) that both cables are owned and maintained by the same company? Just asking John Adams said: If they share the same conduit, doesn't that require (per the NESC) that both cables are owned and maintained by the same company? Just. I need to know is there a Code and/or Standard prohibiting the placement of Communication fiber in the same conduit as power for Safety reasons. :-? and.
