Short flat cable with M.2 M-key plug on one end and OCuLink SFF-8612 socket on the other

LORDWORLD

LORDWORLD M.2 M-Key 2280 to Oculink SFF-8612 Cable 15cm

SKU CH-PZCV-P31FC

A 15 cm adapter cable adds an OCuLink SFF-8612 female port to an M.2 2280 M-Key slot for NVME SSDs or eGPU cards at PCIe 4.0 speeds

  • Adds Oculink port to M.2 2280 slot via 15cm cable
  • PCIe 4.0 signal path delivers up to 64Gbps throughput
  • Backward compatible with PCIe 3.0 for older hardware
  • Mounting holes secure the adapter in compact builds
  • Works with NVME SSDs and eGPU graphics cards

M.2 M-Key to Oculink adapter

The LORDWORLD cable adds an SFF-8612 female port to any 2280 M-Key slot. It carries PCI Express 4.0 signals using the NVME protocol and is backward compatible with PCIe 3.0. The 15 cm length suits small hosts, desktops and laptops, and fixing holes secure the connection.

Builders adding NVME storage or an eGPU

This suits anyone converting an internal M.2 socket to an Oculink link for an NVME SSD or external graphics card. The 64 Gbps peak rate supports PCIe 4.0 x4 workloads. Not for systems without a 67-pin M-Key M.2 slot or projects needing a different connector type.

PCIe 4.0 x4 over Oculink SFF-8612

The single deciding spec is the 64 Gbps PCIe 4.0 x4 link carried through the SFF-8612 interface. If the host M.2 slot delivers four lanes at Gen 4, the cable passes full bandwidth to the attached NVME drive or eGPU enclosure.

Questions about this item

Which cable length should I pick for my build?

This cable is 15cm long; choose it when the OCuLink device sits close to the M.2 slot, and use a longer cable only if the routing distance requires it.

What does the 64Gbps headline figure mean once the cable is installed?

It is the peak PCIe 4.0 x4 bandwidth the cable can carry; actual throughput depends on the host controller, the endpoint device and the NVMe 1.2 implementation.

What interface standard does the OCuLink connector follow and what does it cap in practice?

The SFF-8612 connector complies with the OCuLink specification that supports PCIe 4.0 x4 and SAS-4 24Gbps, so the practical ceiling is the 64Gbps PCIe 4.0 limit of the host slot.
