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 there's a free 10G port for me to use.
It doesn't work that way. The closest you can get is that the device can support either 1G or 10G in the same port (since SFP and SFP+ are physically and electrically the same), but it requires support from the device (since both PHYs have to be implemented). -- Richard A Steenbergen <ras () e-gerbil net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
