Wiki.mikrotik.com lists what SFP+ models can use 1Gig or not.  They are listed 
and it is well documented.

I've had CCR SFP+ ports not wanting to work with GigE SFP modules, but the same 
port works fine with 10G modules.  I know on paper SFP+ is supposed to be 
backwards compatible, but I've had mixed results in real life.

You might have to get an SFP+ module and let it negotiate at 1G.

I've had to set the CCR to 1Gbps FDX (not auto negotiate) in the past to get a 
link to come up. Worth a try if you haven't changed that setting as of yet.

I tried to move a Multimode 1g fiber that was running on a RB260GS to a CCR1032 
8G-2S+.  I moved the mikrotik branded SFP from the 260 to the CCR, so I know 
the SFP is good.  The SFP was recognized, and the phy link was reporting up, 
but I had no RX traffic.  The remote end of the fiber is on a CRS125.  I tried 
to fiddle with all the interface settings I could on the CCR, but nothing 
worked.  I moved the SFP back to the 260, and the fiber is still passing 
traffic normally.  Any thoughts on Settings that were keeping traffic from 
moving.
