FAQs

Q: Will this work with non-InfiniBand devices?
A: It is intended for NDR InfiniBand; Ethernet usage depends on device-specific OSFP breakout support.

Q: Do I need breakout configuration?
A: Many platforms require enabling 800G-to-2x400G breakout on the OSFP port.

Q: Can I mix with QSFP ports?
A: No, OSFP only on all ends.

Q: What is the length?
A: 2.5 meters.

Q: Is any external power required?
A: No, it is a passive copper assembly.
