What to do if there are fiber optic cables or electrical cables underground
This guide walks through each stage of underground fiber installation—from route planning and conduit selection to splicing, termination, and testing—to help ensure long-term network performance and reliability. 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. General Consideration: It is generally not recommended to run fiber optic cables in the same conduit as electrical power cables. Every time an optical fiber cable is cut in the field, small invisible glass shards can be produced. Once this happens, our bodies have no way of removing them. Project success depends on careful planning, precise installation practices, and proper. Underground cables are pulled in conduit that is buried underground, usually 1-1.
