FAQs

Q: Can this be used on Ethernet OSFP/QSFP112 ports?
A: No. It is designed for InfiniBand NDR/NDR200 ports, not Ethernet.

Q: Are additional optics needed?
A: No. This is a passive DAC; it plugs directly into the ports without separate transceivers.

Q: When should I choose optical instead?
A: Choose active optical cables or transceivers for longer distances or when cabling flexibility is required.

Q: Is it backward compatible with HDR (200G) or EDR (100G)?
A: No. It targets NDR OSFP and QSFP112 NDR200 endpoints; backward compatibility is not supported.

Q: Typical use cases?
A: Leaf/spine fan‑out from an NDR switch to 4 servers or adapters with NDR200 ports.
