Black sleeved cable with SFF-8611 and SFF-8639 connectors and SATA power plug

Vszerda

Vszerda Oculink SFF-8611 to U.2 U.3 SFF-8639 NVME cable 1.64FT

SKU CH-MT4R-S7EJE

Connects an Oculink SFF-8611 host to a U.2 or U.3 NVMe drive at up to 12 Gbps over 1.64 ft

  • PCIe 4.0 x4 support for fast NVME drives
  • 12 Gbps data transfer keeps storage responsive
  • Oculink SFF-8611 to U.2/U.3 SFF-8639 connector fit
  • 64FT length gives flexible routing options
  • SATA power included for reliable device operation

PCIe Gen 4 Oculink SFF-8611 to U.2 U.3 SFF-8639

This new cable connects a host Oculink SFF-8611 port to a U.2 or U.3 SFF-8639 NVMe device. It measures 1.64FT and includes a SATA power connector. The link supports PCIe 4.0 and 3.0 x4 lanes for solid-state storage expansion. Builders adding high-speed NVMe drives to compatible backplanes or enclosures will find it suitable.

Practical interface limits

The cable carries PCIe 4.0 or 3.0 x4 signals with a data rate up to 12Gbps per lane. Bandwidth is capped by the PCIe generation negotiated between host and device. Signal integrity over the 1.64FT run meets the Gen 4 specification without active components. No SATA or eSATA protocol is used on the high-speed pairs.

Setup checks before ordering

Verify that your motherboard or add-in card provides an Oculink SFF-8611 4i header. Confirm the target U.2 or U.3 drive accepts SFF-8639 input and that a SATA power source is available. Ensure the 1.64FT length fits your chassis routing without sharp bends. This cable does not convert M.2 or SATA drives to NVMe.

Questions about this item

Which cable length should I choose for my build?

The cable is 1.64FT long; measure the distance between your Oculink host port and the U.2 or U.3 drive bay to confirm it reaches without strain.

What does the 12Gbps figure mean once the cable is installed?

It is the maximum data transfer rate the link can carry when both host and drive support PCIe 4.0 x4; actual throughput depends on the SSD and controller performance.

What interface standard does the SFF-8611 connector use and what does it cap?

The SFF-8611 end uses PCIe 4.0 x4, which caps the link at 12Gbps; it will fall back to PCIe 3.0 x4 if the host or drive only supports that generation.
