[AFMUG] airFiber error correction

[Ken Hohhof]

I am going to assume airFiber has some sort of FEC, but does anyone know if 
it has a retry mechanism (ARQ)?  And if it does have ARQ, what is the impact 
on latency, and can retries result in out-of-order packets?

And has anyone ever heard of a manufacturer offering the option of having 
high priority latency sensitive traffic sent at a reduced modulation rate to 
insure it gets there the first time?
