Engineering Selection Matrix
The variables that decide the correct product
A data rate alone is not enough. These inputs should be aligned before volume deployment.
| Selection variable | What to confirm | Why it matters | Example inputs |
|---|---|---|---|
| Host platform | Switch, NIC, DPU or server port | Defines physical and firmware compatibility context | Vendor / model / port type |
| Form factor | OSFP, QSFP-DD or cable endpoint | Mechanical interfaces are not interchangeable | OSFP800 / QSFP-DD800 |
| Protocol & rate | Ethernet or InfiniBand and target data rate | Changes electrical and link requirements | 400G / 800G / 1.6T / NDR |
| Optical architecture | DR4, DR8, FR4 or project-specific implementation | Changes fiber count, wavelength plan and connector path | Parallel SMF / duplex SMF |
| Reach & fiber | Distance, fiber type and loss budget | Determines optical class and cabling suitability | 500m / 2km / project selected |
| Topology | Native link or breakout | Changes port mapping and cable / optic selection | 800G native / breakout |
| Commercial requirement | Quantity, sample need and required date | Determines current supply and delivery feasibility | Sample / volume / target delivery |
