[The Computer Audiophile]

Hmm. I better ask Jesus what this means.

 

DELUXE FEATURES

• Supports both 100 speed and 1000 speed network devices

FEATURES

• For 1000 speed capable networks only

"Compatibility list" is really not necessary.  All you need to do--if you wish to use a pair of SFP+ fiber optic transceivers in a device whose SFP port is 1Gbe-only (such as EtherREGEN, opticalModule, opticalRendu, etc.)--is to be certain that the cage at the OTHER end (switch typically) is also a 1GBe-only SFP port and is NOT a device that supports 10GBe (so-called "SFP+ port"). The connections are all electrically the same between SFP and SFP+. And the transceiver modules themselves do not negotiate anything. It is all about the devices you plug them into!

But 1Gb SFPs won’t do 10Gb in 10Gb ports.

That is correct. But only because the performance of their circuits are not up to the speed. 

There must be something in the SFP+ telling the switch that it handles 10Gb, else the switch would just try to send 10Gb in a 1Gb SFP.

See the post Alex shared. It talks about the pin on the connector that is grounded on the SFP, an SFP+ port can apply a pull up on that port, when SFP is inserted it will be pulled down, an SFP+ will not pull it down so the switch can if it wants to, switch the speed. A switch with SFP+ port is free to either run at just 10Gb, have an external mechanism to change the speed (physical switch, web page configuration etc) or use the above property of SFP modules.

That’s what I was looking for. It would seem rather dumb if I could put an SFP in an SFP+ port and have it try to send at 10Gb with all kinds of issues rather than go down to 1Gb. 
 

Thanks John.

Here's a shoutout to Andrew Gillis of Small Green Computer. I'm not sure how he finds time to do this, but he seems to respond to all emails, including from random people asking him stupid questions :) That's first class customer service. Here's wishing that SGC will do well and enrich the audio community with interesting stuff along the way.

 

(Unfortunately the opticalModule is still sold out as of this date).

 

I'm with you 100% Andrew is terrific. As is Jesus at Sonore.
