40G QSFP28 for CRS510-8XS-2XQ-IN

Hi

I am new to Mikrotik

I have a CRS510-8XS-2XQ-IN and I would like to use the two 100G ports

I am limited to 40G due to the provider offering 40G and not 100G

What 40G LR optic I can use, DAC is not an option in my case ?

Would this optic work ?

Thanks in advance

Product brochure, available from ifficial product page at https://mikrotik.com/product/crs510_8xs_2xq_in , mentions 40Gbps backward compatibility. Which 40Gbps QSFP28 modules are compatible is another question. FS does state Mikrotik compatibility so it's quite probable that modules from your link will do just fine.

Thanks, yeah finding the correct compatibility is the issue…
