Can you get digital diagnostics info from these too?  Here's the info 
from one of our standard Juniper SFPs.  Note that "show interfaces 
diagnostics optics" only works if you give it an interface argument 
(including wildcards).  Otherwise it shows the standard "show 
interfaces" information for all ports, but no digital diagnostics 
info.

On SFP's that don't support this info (or JunOS at least doesn't 
support retrieving it) I get this:
