RE: Issues concerning 10GbE speed standards


Let us use the word "quality", I do not mind whichever the word we use.

The BER (Bit Error Rate) is a definition to include all errors, but not to
use error correction for BER measurement.

I think that is an opinion, it is not a fact. A wish list perhalf?

I think BER measured without error correction indicates some sort 
of the quality of the link, not its reliability. BER measured with error 
correction shows the measurable link reliability.
