[AFMUG] Ethernet Vs Fiber in Space

[Nate Burke]

I'm watching the live spacewalk that is on.  They keep referencing that 
they are routing a new 'Ethernet' cable on the outside of the 
spacestation as a redundant data path between 2 modules.  I would think 
that they would do everything as Fiber to prevent RF Interference.  Is 
it because they just recently upgraded the computers from Token Ring?  
Or is it really a fiber line, and they just keep calling it Ethernet.  
Or are Fiber components really heavy to lift into space, or big power 
draws?
