That's an amazingly expensive optoisolator.

Seriously, though, that's exactly what you're describing, and about what I'd
suggest in a no-other-option scenario -- but if it's possible to pull fiber
through the conduits, it would probably be far less expensive long term, or
even medium term if the physical fiber spools can be bought cheaply enough.
