|Is THERE A STANDARD THAT STATES YOU CANNOT HAVE FIBER AND COPPER PULLED IN THE SAME CONDUIT. IF SO, WHERE IS THAT STATED?|
Answer by Dmitri Abaimov posted 27 Jun 2005
No standard says that. That is, if copper is used for communications circuits and not power, you CAN pull it together with fiber. What you MAY want to avoid though, is to pull a heavy multi-pair copper cable AFTER a fiber cable has been installed in that conduit. It's being routinely done in the reverse order though.
Mind you: there are so many different designs of fiber cable, one stronger than the other, so the actual answer should in real life depend on the components you are using, size of the conduit and its length.
Alternatively, you can pull an inner-duct for the fiber, and that gives enough protection to pull just whatever you pleased through the same conduit with fiber (as long as it does not carry electrical power)
