FRULink 10G SM Module - Can a 10G sm module run at 1G

[hendle]

We recently deployed the WS-C3750X-48T-S with a 10G SM Module.  The 10G SM Module has a fiber sfp and ismy only fiber ports.  Is it possible to run a 10G fiber sfp  port at 1G?

Currently SFP+ will only negotiate to 10 Gbps and nothing less.  SFP will always negotiate to 1 Gbps and nothing less.

some SFP can work at 100Mpbs speed :-)

C'mon, I'm speaking in the context of the the OP asking if SFP+ can/can't operate in 1 Gbps (and not 100 Mbps).  

Yes, there are SFP that can operate only at 100 Mbps and nothing more than that.

Yes, it is. I have worked with this module working just fine with a 1000Base SFP.
