Pablo was going that way. You can certainly do it without Ethernet. You need some form of simple low-rate protocol to transfer measurement data and time. > If Pablo is going to design their own hardware, perhaps something like > 1550nm transmission on a high grade single mode fiber that should a nice > loss budget for the splices on 27km.

Well, guess what I do for a living...
