Fiber optic cable
Fiber optic cable
(OP)
Hi,everybody.
It is known that the data cable is not advisable to share the same conduit/trench with the power cable to avoid any unnecessary data transmission interference.
As i know, fiber optic cable is also a data transmission cable.So, is there any problem if fiber optic cable share the same conduit/trench with power cable?Is fiber optic cable got any special feature make it an exception in this case?
Thanks for your comments.

In the cables dpc mentions that share conductors with fiber optics the concern is not with the optical circuits but the conductors that may accompany the fiber optics in the same cable. If these conductors are not acceptable by code to be included in the conduit with power conductors, the composite cable may be banned from sharing the conduit. This is a limitation of the insulation rating of the metalic conductors with the fibers, not the fibers themselves.
Beware of composite cables with low voltage ratings.

There's another issue you may wish to consider: Fiber Optic cables are easily damaged, and are not particularly heat resistant. It is possible that a fault on the power cables could damage your fiber, right in the middle of your conduit where it can be difficult to splice. This happened to us once. We had to replace 300m+ of 24 strand cable (and introduce an unplanned splice), when a power cable failed right under a street, taking out the FO cable too.

I agree with tinfoil in that "Fiber Optic cables are easily damaged". Consideration to installation "pull by's and/or pulling with" other types of conductors (power cables) could damage some of the fiber conductors as well as the bend radius for fiber cables should be taken into consideration. In my world (nuclear) fiber optic cables are installed in there own raceways (conduits). Not that this is the norm in the real world.

I have a sample of 3-phase 15 kV UG cable from Okonite with fiber installed directly in the cable assembly.

If there are conductors included with the fiber optic cable they should have approval stamps and a voltage rating. The voltage rating should be equal to the highest voltage used in the conduit or cable.

Friends don't let friends pull power and fiber thru the same conduit!
