    It has been conjectured that the easiest way to locate a buried fiber optic cable is to start digging.

    (The actual easiest method is to install the conduit or direct burial cable with tracer wire)

      Fiber was all installed long after we knew locating it was important. I suspect it all had a tracer wire installed with it. Of course sometimes the tracer wire can break.

      Before fiber a lot of things were put into the ground with no thought how you would find it again.

        Indeed, tracer wire is usually bonded to a (sacrificial) magnesium anode, but it’s a crapshoot whether the tracer wire is still intact.

        I sometimes hire directional boring and excavation contractors and if there’s any doubt as to where an electrical conduit or natural gas pipe is, I opt for the hydrovac truck to minimize risk.
