Host and port layout
Record switch and NIC models, software releases, supported port rates and breakout configurations at both ends. A matching form factor alone is not a compatibility decision.

Data centre and cloud interconnects
Plan a staged 100G, 400G or 800G refresh around the host ports, installed fibre and rollout windows.Define the project before selecting the optics.
A capacity upgrade starts with the links that need to change. Separate server-to-switch connections, spine–leaf links and connections between equipment rooms before selecting optics. Keep the existing links and the target architecture in the same port schedule so that migration and spare requirements remain visible.

Decisions that shape the shortlist
Installed cable plant
Record measured link length, fibre type, connector and patch-panel path. Compare a transceiver-and-fibre assembly with DAC or AOC where the rack layout allows either approach.
Migration sequence
Identify links that stay at 100G, links moving to 400G or 800G, and the temporary connections needed during changeover. Include replacement units and maintenance windows in the bill of materials.
Product families to review
Select the exact model after checking the host, cable path and operating requirements.
100G QSFP28
Review existing aggregation links and the retained spare pool.

Browse products →From evaluation to rollout
- Confirm both endpoint models and supported port modes.
- Validate representative samples on the intended software release.
- Record recognition, diagnostics and link behaviour under the planned configuration.
- Agree the model list, cable lengths, quantities and delivery stages before rollout.
