Optical link planning
Cisco QDD-2X100-CWDM4-S 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.
- This module provides two 100G optical links. Do not specify it as a single 400G optical link.
- 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.
