FAQs

Q: Will this work between an 800G switch port and two 400G NICs?
A: Yes, provided the 800G port supports 2x400G breakout and the endpoints have QSFP112 400G ports.

Q: Is this cable active or passive?
A: It is a DAC twinax cable; no external power is required. Check your platform guide for supported DAC types and lengths.

Q: Can I use this instead of optical transceivers for short runs?
A: Yes. For very short distances within the rack, DAC is a cost-effective, low-latency alternative to optics.
