Description

Active Optical Cable breakout for splitting one 400G QSFP56-DD port into four 100G QSFP28 links over integrated multimode fiber. Ideal for low-weight, low-EMI cabling across medium runs in high-density fabrics. Implements 400GBASE-SR8 on the DD side and 100GBASE-SR4 on the QSFP28 legs for plug-and-play interoperability.

Features

- 400G-to-4x100G optical breakout for simplified medium-reach cabling
- Integrated multimode fiber with 850 nm optics
- Standards-based 400GBASE-SR8/100GBASE-SR4 interoperability
- Lightweight, flexible, and immune to electromagnetic interference
- Digital diagnostics for monitoring link health
- Plug-and-play in dense leaf–spine and TOR deployments

FAQs

Q: Do I need separate fiber patch cords?
A: No. An AOC integrates the fiber within the cable assembly; just plug in the connectors.

Q: Is my device compatible?
A: Any QSFP56-DD 400G port that supports 1x4 breakout to QSFP28 100G should work. Verify platform breakout support and coding requirements in your hardware documentation.

Q: Is FEC required for this breakout?
A: Yes. RS-FEC is typically required per the 400GBASE-SR8/100GBASE-SR4 specifications.

Q: Can this AOC be used for 4x25G?
A: No. It is intended for 4x100G breakout from a 400G QSFP56-DD port.

Q: What fiber type does it use?
A: It uses integrated multimode fiber operating at 850 nm; no external fiber selection is needed.
