Fibre cable specs?

Hi!

I found the draft "X3T11/Project 755D/Rev 4.3", which seems close enough
to the "X3T11/Project 755D/Rev 4.2" draft which sun claim that the SSA
complies(sic!) with at:
http://lurch.cit.buffalo.edu/TechInfo/FiberChannel/fibre_channel_physical_interface.txt

I believe it says that it should work but be constrained to the shorter
cable length of 700m instead of 2km. However, it wasn't completely clear
to me so I suggest that you study the draft yourself too.

Hope this helps!
