Wondering if you can use the same conduit for electrical and data cables? Learn about the risks of interference, best practices, and installation tips for cable protection.

The NEC and Optical Fiber Cable and Raceway Rules | EC&M

Because optical fibers don''t carry current, the normal NEC rules related to ampacity don''t apply — unless, of course, you run them with current-carrying conductors or use a fiber-conductor

Optical fiber cable

I''m not going to pretend to know all the nuisances of the code but it appears it may be ok if the fiber optic cable is ran with the current carrying conductors when they are associated.
