OCuLink Adapter Cards for PCIe, NVMe & eGPU

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.

How to Choose an OCuLink Adapter Card

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.

FAQ

What is an OCuLink adapter card used for?

It exposes PCIe lanes through an OCuLink interface for NVMe storage, eGPU docks, mini PCs, workstations, servers and lab validation.

Should I choose SFF-8611 or SFF-8612?

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.

What details are needed for an OCuLink adapter quote?

Send the host slot, OCuLink connector, PCIe generation, lane configuration, internal or external orientation, quantity, country and target device.

Can LetLinkSo provide OCuLink adapter cards without public pricing?

Yes. OCuLink adapter projects are handled as B2B inquiries because compatibility, quantity and configuration affect the sourcing path.
