I happen to be aware of a non-standard Ethernet PHY made by Broadcom
that can handle these kinds of distances (up to 500m) and is
compatible with standard Ethernet as well. It's called BroadR-Reach:
They originally announced it in 2007 for long-distance wiring runs
over cheap wiring for hotels, apartments, etc. But it's recently been
re-targeted for automotive ethernet use, since it gets you 100Mbit/s
over a single twisted pair.
Unfortunately, I don't know how you'd find actual products that use it
that would fit your needs, though I imagine some must exist. Good
