Compare OCuLink SFF-8611/SFF-8612 adapter cards for PCIe expansion, NVMe SSDs, eGPU docks and server validation. Confirm host slot, lane layout and internal or external orientation before requesting a quote.
An OCuLink adapter card connects a PCIe slot or M.2 M-Key host to an OCuLink SFF-8612 adapter side and, where required, an SFF-8611 cable path. Choose the card by the host interface, lane count, PCIe generation, internal or external orientation, target device, and power design rather than by the OCuLink name alone.
| Project | Start with | Confirm before quoting |
|---|---|---|
| eGPU or GPU dock | PCIe x4 to OCuLink card | External SFF-8612 layout, cable end, clearance, GPU and power |
| M.2 NVMe expansion | M.2 to OCuLink card | M-Key keying, PCIe generation, SFF-8611 cable and SSD path |
| Server or workstation | PCIe x8 to OCuLink card | Lane allocation, internal orientation, bend radius and validation |
For a model match, send the host slot, OCuLink side, PCIe generation, lane count, orientation, quantity, country and target device through the B2B quote form.
Server interconnects, NVMe expansion, eGPU docks, storage validation, workstation upgrades, and compact chassis routing.
MCIO, OCuLink, SFF-TA-1016, SFF-8611, U.2, M.2 NVMe, EDSFF, Slim SAS, and PCIe adapter layouts.
Share the target platform, connector type, PCIe generation, length, and quantity for quote matching.

| LLS-CD-1PC4OC-01 | PCIe 4.0 x16 to OCuLink Adapter Card (Internal) | OCuLink adapter | PCIe 4.0 | High-speed PCIe connectivity projects |
It exposes PCIe lanes through an OCuLink interface for NVMe storage, eGPU docks, mini PCs, workstations, servers and lab validation.
Confirm whether the host or adapter side needs the board-side SFF-8612 layout or the cabled SFF-8611 connection, then check connector direction and lane count.
Send the host slot, OCuLink connector, PCIe generation, lane configuration, internal or external orientation, quantity, country and target device.
Yes. OCuLink adapter projects are handled as B2B inquiries because compatibility, quantity and configuration affect the sourcing path.
See the full OCuLink cable and adapter card product cluster for SFF-8611 and SFF-8612 projects.
Compare M.2, PCIe slot and SFF-8611 matching before selecting an adapter card.
Check cable direction, length, shielding and eGPU compatibility for the complete connection path.
