3. Switch-to-four combinations of 200G ConnectX-7 and/or BlueField-3
A Twin port OSFP transceiver using two, 1:2 ber splitter cables can support up to
four adapter and/or DPU combinations. Each of the two, 4-channel 1:2 ber splitter
cables (MFP7E20-N0xx) can link to a 400G transceiver up to 50-meters in either
OSFP (MMA4Z00-NS400) or QSFP112 (MMA1Z00-NS400) form-factor. The
electronics, optics and optical connectors are the same for both single port OSFP
and QSFP112 form-factors. The two- ber channel ends only activate two of the
lanes in the 400G transceiver creating a 200G device and automatically reduces the
power consumption of only the 400G transceivers from 8 Watts to 5.5 Watts. Twin
port OSFP power consumption remains at 15 Watts.
- Only ConnectX-7/OSFPs can accept single port OSFP.
- QSFP112 form-factor is used in ConnectX-7/QSFP112s and/or BlueField-
3/QSFP112 DPUs.
- Any combination of ConnectX-7 types and BlueField-3 can be used at the same
time on Twin port OSFP transceivers.
