Your two switches need a 100G link and you don't want to source separate transceivers for each end. This Ubiquiti QSFP28 direct attach cable plugs straight in and runs at up to 100 Gbps. No optics to buy, no compatibility cross-referencing. Ten cables in the box, so you can wire a full rack or cover spare ports in one go. The 0.5m length keeps things tidy between adjacent units on the same shelf
