I don't know for sure but here are some possible reasons: - they are designed to operate in very hostile environments (welding, etc.)
- they are concerned about interfering with other analog devices (WiFi uses shared spectrum)
- timing is critical and retransmit delay is a potential problem
- they were designed that way back when WiFi technology was less mature and there's no cost pressure to change
- they are over engineering and butt covering in case of lawsuits

Hi Rick,
Good points.
The NC milling optic fiber cables were passing by huge 3 phase motors.
Maybe the strong magnetic fields would have interferred with a cable?
I think a standard Ethernet cable would be fine for the short distance of less
than 100 meters in the case we're talking about -
a telescope, observatory control system.
cheers
