FAQs

Q: Is this cable compatible with both 100GbE and InfiniBand EDR ports?
A: Yes. It supports 100 Gigabit Ethernet and InfiniBand EDR as long as both endpoints support passive QSFP28 DAC.

Q: What is the difference between 26AWG and 30AWG versions?
A: 26AWG has thicker conductors for lower loss and is used for longer passive runs (e.g., up to 5 m). 30AWG is thinner and typically suited for shorter lengths.

Q: Do I need any optics or additional modules?
A: No. This is a passive QSFP28 DAC with integrated terminations—no separate optics are required.

Q: Can I mix vendors on each end?
A: Interoperability depends on each device’s DAC coding policy. Many platforms accept standard QSFP28 DACs, but some may require approved coding.

Q: Is the cable hot-pluggable?
A: Yes. QSFP28 interfaces are hot-pluggable; insert or remove with care following device guidelines.
