Two 25G switches sitting on the same rack shelf. You don't need a transceiver and a patch cord for that. The SM6220-1M is a 1-metre direct attach cable with SFP28 connectors on both ends. Plug one end into each switch, done. No module to seat, no LC connector to align, no light loss to worry about. It drives 25 Gigabit Ethernet across that 1-metre gap with zero active components in the middle. Three-year warranty
