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: https://www.broadcom.com/products/Physical-Layer/BroadR-Reach-PHYs/ . 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 luck! --Levi /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
