[c-nsp] interface between PHY chip and SFP transceiver

[Phil Bedard]

There is. It's typically called the MII or Media Independent Interface.  There is the XAUI interface for 10G.  You can look it up on Wikipedia.

Jörg,

I checked this before sending my initial e-mail :) Still, this
interface between the SFP and PHY chip should have some sort of
industry-wide common name?


thanks,
