It's been some years, but there is (or was) a guy named Carl, he has a bore rig that can drill perfect holes in lava, and he can throw a chain around the boom to raise the pipe. Try ask the nice ladies at Allied Equipment Rental in Shipman, they knew where to find him last time I went looking.
Charged me $150. Totally worth it. Solid pahoehoe is far stronger (and cheaper) than any concrete I could pour to backfill a bigger hole.
See the guys at Alpha Electric for the hook on the top, they have a clamp-on assembly, this avoids drilling holes in the pipe. Breaking the galvanization is just asking for rust.
Pole needs to be 14' tall if the line is crossing a road or driveway. A 20' pipe with 5' in the ground leaves you 15', so this requirement is easily met. Not sure they will allow shorter poles in other instances.
Schedule 40 should be more than enough for fiber.
Thread a cap on the exposed end. This should be obvious... but...
They want the pole to be within 100' of the line. Longer distances might be allowed with fiber (less loading) but you'd have to ask them.
Copper terminus used to require two ground rods. Probably unnecessary for fiber. Again, ask.
Past the pole, if your house is close/tall enough, they'll hang it on your house. They will also pull it through conduit. If your conduit has no string, their fish tape is 300', include some access pulls if the conduit run is longer than that. Use at least 1-1/4" conduit. It doesn't have to be buried.
Side note: HPM has a selection of access pulls for 1-1/4" and 1-1/2" PVC conduit. I was not able to find these elsewhere. Similarly, the midspan access pull should be a "C-body", but nobody carries these on-island. Use a T-body and glue some kind of plug on the side port. Lowe's has gray PVC caps, or find something in the plumbing section (other than UV resistance, gray/white PVC are compatible for size and glue).
Telcom installers are "pre-blessed" by NEC section 70 (low voltage communications) and the HCC. No permits required.
