FAQs

Q: Is this cable suitable for 400GbE switch-to-switch links up to 15m?
A: Yes, it is designed for 400GbE QSFP-DD ports with a fixed 15m reach.

Q: Does this require any special drivers?
A: No drivers are required; it is hot-swappable and recognized by compliant ports.

Q: Can I use it instead of separate SR8 transceivers and MPO fiber?
A: Yes. AOCs integrate optics and cabling, offering a simpler alternative for short distances.

Q: Is the cable bend-friendly for tight racks?
A: AOCs are generally more flexible than copper DACs, aiding cable routing.

Q: Does it support digital diagnostics?
A: Yes, it supports DOM/DDM for monitoring key link parameters.
