I previously included this in a more complicated query (“Interoperable ASR1000 XFP for SFP-10G-LRM ?”) that didn’t generate any responses, so here is the revised question:
Will a SFP-10G-LRM interoperate with a SFP-10G-LR if I connect using single mode fiber?
(Fiber length would not exceed 100 meters.)
Power and wavelength specifications for the two SFP+ modules seem to indicate that they would work together:

I’m just concerned that there could be some protocol differences. Otherwise I’m not sure why there would be two different standards, i.e –LR and –LRM.
I checked the "definitive source for everything" and that didn’t clarify LR/LRM interoperability either:

Thanks.
