You can plug SFP module (copper or fiber) into any SFP+ port.
So, on 10G port you can run either 1GE or 10GE.
A well known counterexample of this is the Cisco Nexus5k, where only some
of the SFP+ ports are 1G capable (first 8 on the 20 port box, and the

Not true. Some devices support this, since SFP and SFP+ are physically
and electrically compatible, but not all. The de

Are there are any optics that plug into 10G ports but have a copper or
optical 1G interface? There's some equipment that I'm specing where it is
$10K for a multi-port 1G card, even while I really may only *occasionally*
need a single 1G port and the

I'm curious also. Could you use a SFP in a ten gig port if you only need
4gb of throughput?

Jason - there are no SFP-10G parts based off of the original SFP; they
all are based on the SFP+ standard, so there will be no issues with the
optic not being able to work at the full 10Gbps it's rated for.
