FAQs

Q: What platforms can use this cable?
A: Devices with QSFP56-DD 400G ports that support 1x4 breakout to QSFP28 100G are compatible. Always verify breakout and coding support in the platform release notes.

Q: Is any external fiber cabling required?
A: No. The AOC is a complete assembly with integrated multimode fiber.

Q: Does it support DOM/DDM?
A: Yes. The AOC supports digital diagnostics for monitoring optical parameters.

Q: Is FEC needed?
A: Yes. RS-FEC is typically required with 400G/100G optical breakout per the standards.

Q: Can this be used as four independent 100G links?
A: Yes. Each QSFP28 leg presents as a separate 100G link when the host supports breakout.
