FAQs

Q: Is this DAC suitable for end-of-row connectivity?
A: Yes, the 3m length is well-suited for short intra-row links depending on your rack layout.

Q: Does it support auto-negotiation between 25G and 50G?
A: Rate negotiation depends on device capabilities; some platforms support 25G fallback, others require 50G only.

Q: Are the connectors standard SFP form factor?
A: Yes, it uses the SFP56 form factor with the same physical envelope as SFP+ and SFP28.

Q: Any special cooling or power needed?
A: No, it is a passive cable with negligible power draw and heat.

Q: Can I mix vendors on each end?
A: Mixed-vendor links may work if coding is compatible; consult your platform’s transceiver compatibility guide.
