Fiber (with fabric innerduct) and 480V Conductors in PVC Conduit

[YouConduit!]

NEC 770.133 (2023) permits non-conductive fiber optic cables and <1000V conductors to share the same raceway.

MaxCell fabric innerduct has a melting point of 419 deg F (215 deg C).

My question is: Can I put a 480V/3ph circuit and 3-cell innerduct with a 12-strand non-conductive fiber optic cable in it all in the same 4" PVC conduit? Why or why not? Assume conduit fill requirements are met for the purposes of this question.

Thanks in advance!

I don't see why the inner duct would make any difference.
