FAQs

Q: Will this work in any QSFP+ 40G port?
A: Yes, provided the port and platform support 40G to 4x10G breakout operation and the 10G endpoints support SFP+ AOC.

Q: Do I need separate transceivers?
A: No. This is an integrated AOC with QSFP+ and SFP+ ends built in.

Q: What fiber and connectors are used?
A: The cable is an integrated multimode AOC; it uses no LC connectors—ends are QSFP+ and SFP+ plugs.

Q: Is it hot-swappable?
A: Yes. Both QSFP+ and SFP+ ends are hot-swappable when used in compatible ports.

Q: What is the supported reach?
A: 5 meters end-to-end.
