Fiber optic cables and electrical cables are on the same cable tray
According to the NEC, nonconductive optical fiber cables can occupy the same cable tray or racewa y as electrical conductors. The existing 2" conduit contains 4x 1/0 XLPE cable (rated for direct-burial), so I plan on pulling outdoor rated, non-metallic fiber through the same conduit. My original plan was to trench new conduit and run CAT8, but given that the existing run is all "customer side" and installed by the former. The NEC breaks down fiber optic cables into two main categories: nonconductive and conductive. This is due to several potential risks and complications that can arise from such an arrangement. But there are more aspects of them when compared together. It often use.
