QSFP+ module compatibility

Hey,

 

I know that you can't mix a MMF module with SMF cables, or SMF module with MMF cables, but I haven't found any articles on QSPF+ ports being only compatible with one type of module. Are they always interchangeable? 

 

I want to connect two Mikrotik's CRS326-24S+2Q+RM in two different rooms. DAC cables are not an option. 

 

On Mikrotik's website they only have a MMF module with a MTP/MPO connector (Q+85MP01D) and it is the only module on the compatibility list for this switch.

 

Will a SMF module work with it? What are some cheap options to connect these two switches? It might acually be cheaper to connect 4 sfp+ ports and bond them...

SFP/SFP+/QSFP+ are all compatible regardless of mode of the module. There are even adapters to turn a QSFP+ port into a SFP(+) port.

Thank you, yes I saw the adapters while I was browsing for different modules. We are already using SFP+ to RJ45 adapter for our 10Gbs network for the office.
