Hi,

Using a QSFP+ as a TOR, I want to utilize the 2 x 40Gbps QSFP+ for backhaul. What are my options in terms of Mikrotik switches, for high capacity / redundant 40Gbps links? I don't see any other switches from Mikrotik with a QSFP+ form factor, except for the CRS326-24S-2Q+RM

Can I link a QSFP+ to a SFP28 (CRS518-16XS-2XQ), with a 25Gbps link (and what DAC / Cable will be recommended)?

Alternatively, what alternatives in terms of switching, is there from Mikrotik in terms of 40Gbps / QSFP+ ports? I can't seem to see anything that will be compatible with QSFP+, unless you go to 4 x 10Gbps ports?
