56GbE is an NVIDIA proprietary link speed and can be achieved while connecting an NVIDIA adapter card to NVIDIA SX10XX switch series or when connecting an NVIDIA adapter card to another NVIDIA adapter card.
Speed that supports both NRZ and PAM4 modes in Force mode and Auto-Negotiation mode.
Speed that supports PAM4 mode only.
