FAQs

Q: Is this cable passive or active?
A: It is a passive twinax DAC, requiring no external power and offering ultra-low latency.

Q: Do I need separate optical transceivers for this cable?
A: No. DACs integrate the connectors—just insert into SFP28 ports at both ends.

Q: Does it support 10G operation?
A: It is designed for 25G. Some devices may allow 10G fallback, but support is device and software dependent.

Q: Can this be used for breakout connections?
A: No. It is a 1x25G SFP28-to-SFP28 cable, not a breakout type.

Q: What standards does it follow?
A: 25GBASE-CR over SFP28 and SFP28 MSA mechanical/electrical interfaces.
