Fiber optic cables and electrical cables should be placed in the same cable tray

The NEC explicitly states that conductive optical fiber cables are not allowed to occupy the same cable tray or raceway as the aforementioned electrical conductors. The key difference here is safety. Nonconductive Optical Fiber Cables: These are typically indoor/outdoor rated fiber cables. This includes conductors for electric light, power, Class 1, non-power-limited. Maintaining proper separation between power, data, and limited energy cabling is foundational to system performance, safety, and code compliance. Separation isn't just an EMI precaution — it protects signaling, reduces rework, and ensures pathways meet inspection expectations across risers. Informational Note: 1 method of defining a cable that is low-smoke producing cable and fire-resistant cable is that the cable exhibits a maximum peak optical density of 0. 50 or less, an average optical density of 0. 52 m) or less when tested.
