SFP56 Direct Attach over Copper (DAC) cables
Always refer to the Datasheet or QuickSpecs for the Switch product to see the current list of supported transceivers.
IMPORTANT:
Direct Attach over Copper (DAC) cables have a minimum bend radius of typically 4x the diameter of the cable (approximately a 1" bend radius). Handle DAC cables carefully to ensure that you do not crimp or bend the cable beyond a 1" radius. Otherwise, you risk damaging the cable.
