I've for decades have opted to use pvc conduit for underground installations. This way I can pull/replace wire. Reading this made me realize that putting fiber inside conduit in inaccessible areas would be a safe way to go.

Years ago some electronics sensors were replaced and started having problems. I came to realize it was a voltage drop with the new increased load. I was able to pull in new larger wire by using the old wire as the puller.
