XAUI, SFF connectors


As is usually the case, you always bring up interesting tangential
issues in your email. This time it's:

"Given the form factor that would use XAUI, SFF connectors would not be
a requirement."

What in the world does the XAUI interface, specified for use as an XGMII
extender, have to do with SFF connectors???

Please enlighten me. 

Best Regards,
