Direct burial/Fiber

[Rizz]

Any one know what the burial depth for fiber is? Just under the lawn, not under a slab or driveway or anything. Iv lookd in 770 but didnt find much.

Wouldn't T.300.5 apply? I don't know for sure.

Per 770.3, 300.5 does not apply to optical fiber cable. The burial depth is a design issue and not a code issue for fiber.

I didn't think 330.5 applied but I couldn't find anything else for depth. You are correct in that Art. 770.3 states that art. 300 applies only where it is referenced in art. 770. I misread that part and thought all of chapter 300 applied.

Thanks for the correction.
