Re: XAUI, SFF connectors
Rich,
What need does an interface card have for SFF connectors that can only put
one optical port within a 13 inch copper etch radius? From what you and
others are making us believe, the form factor requirements for 10GbE are so
large that SFF connectors are a non-issue. If 10GbE interfaces are going
to be so dense that we will need SFF connectors, why did we need XAUI? I
can't see how you would need both.
Thank you,
Roy Bynum
