3.1.1 Data Interfaces

The data interfaces use QSFP28 connectors. The full list of interfaces per system is provided in
Table 3, "Speed and Switching
QSFP28 cable or connector for 25/40/50/56/100GbE, or 1/10/25GbE when connecting through
Mellanox QSFP28 to SFP28 (Dynamix™ QSA) adapters, hybrid or split cables. The systems
offer support of up to 3.5W transceivers in all QSFP28 ports, and support of up to 1.5W in all
SFP28 ports.
Some QSFP28 ports and SFP28 ports support higher power consumption transceivers, as detailed
in the following table:
