Interface options
QSFP-DD cage:
1 x 400GBASE-DR4, 1 x 400GBASE-SR8/FR8/LR8, or
2 x 200GBASE-CWDM4 (dual CS connector), or
1 x 200GBASE-DR4/SR4/FR4/LR4/CR4, or
4 x 100GBASE-DR, or
1 x 100GBASE-SR4/LR4/CR4, or
8 x 50GBASE-SR/CR, or
2 x 50GBASE-SR2/LR2/CR2, or
1 x 40GBASE-SR4/LR4/CR4, or
4 x 25GBASE-SR/LR/CR
QSFP56 cage:
Same as QSFP-DD minus support for 400G speeds, 2 x 200GBASE-CWDM4, 4 x 100GBASE-DR and 8 x 50GBASE-SR/C.
Actual interface options depend on the capabilities of the inserted transceiver. Both cages can be active simultaneously except when the QSFP-DD cage runs 400GE, 2 x 200GBASE-CWDM4, 1 x 200GBASE-SR8, or 8 x 50GBASE-SR/CR. Both cages must run with the same base interface configuration (e.g. 2 x 50G).
