10GTek DAC Cables...
For the server-to-switch connections I used 10GTek DAC cables, which are an easy way to wire up 100G without dealing with optics. In my setup they negotiated at 100Gbps once I fixed the FEC mode on the MikroTik side, and the cable info showed up correctly in the interface details.
