M.2 M-Key to OCuLink Adapter

This 15 cm cable adds an OCuLink SFF-8612 female port to a 2280 M-Key slot. It carries PCIe 4.0 signals using the NVME protocol at up to 64 Gbps. The assembly includes a 67-pin M.2 male connector and fixing holes for secure mounting. It suits builders who need to connect U.2 SSDs or eGPU enclosures to an M.2 socket.

Suits compact hosts needing OCuLink

The short length fits small desktops, laptops or servers where space is tight. It works with PCIe 3.0 and 4.0 devices such as graphics cards, SSDs or expansion cards. Builders who need a longer reach, a different key type or an internal SFF-8611 connector instead of SFF-8612 should look at other options.

PCIe 4.0 at 64 Gbps decides fit

The link runs at 64 Gbps and supports NVME 1.2, matching PCIe 4.0 x4 bandwidth. If the target device requires PCIe 5.0 speeds or a protocol other than NVME, this cable will not deliver the needed performance.

Questions about this item

How do I install the 15cm Vszerda cable between an M.2 2280 M-Key slot and an OCuLink SFF-8612 device?

Insert the 67-pin M.2 Key M male connector into the host M.2 2280 slot and secure it with the fixing screw; then attach the OCuLink SFF-8612 female connector to the target device using an optional OCuLink cable.

What maintenance or replacement will this cable need over time?

The passive 15cm cable has no moving parts or firmware; inspect the connectors for dust or bent pins and reseat if signal errors appear, otherwise no scheduled replacement is required.

What is the first performance limit reached under sustained PCIe 4.0 loads?

The link tops out at 64 Gbps aggregate bandwidth, so sustained NVMe or eGPU traffic will saturate the PCIe 4.0 x4 lane ceiling before any cable-specific bottleneck occurs.
