QDD-400G-BD — product overview
Cisco QDD-400G-BD delivers 400 GbE connectivity through a QSFP-DD module with a LC optical interface. Its specified reach is 50m (OM3) 70m (OM4) 100m (OM5) over MMF.
Optical link planning
Cisco QDD-400G-BD belongs to the Cisco QSFP-DD Optical Modules range. Use the model-specific specifications above when comparing alternatives.
- Check host QSFP-DD support and the required FEC configuration before ordering. Match the connector polish and fiber topology to the exact module; MPO and duplex links are not interchangeable.
- Match the full module P/N with the host port and supported firmware. A shared form factor alone does not confirm interoperability.
- Review the specified fiber grade, connector, link distance and FEC conditions together with the far-end module.
