PCIe 4.0 Oculink to U.2 U.3 cable
This EN-Labs cable connects a PCIe Gen 4 Oculink SFF-8611 host port to a U.2 or U.3 SFF-8639 NVMe SSD. It supports PCIe 4.0 and 3.0 x4 links for high-speed storage expansion. The 1.64ft length suits compact server or workstation builds. Builders needing a different connector standard or longer reach should choose another cable.
Sleeved black cable with SATA power
The black sleeved SAS cable carries two connectors and includes a SATA power lead for the drive side. This arrangement lets you power a U.2 or U.3 device directly from a standard SATA supply. The fixed 1.64ft length limits routing options in larger enclosures. Installers who need internal locking latches or a different power source will need an alternative.
Passive design for PCIe 4.0 speeds
The passive assembly supports data transfer up to 12Gbps over a PCIe 4.0 x4 link without active components. No fan or external power is required for the cable itself, so it adds no audible noise. Thermal load depends entirely on the attached SSD and host controller. Users expecting higher bandwidth or active signal conditioning must select a different solution.

Questions about this item
What practical limit does the PCIe 4.0 x4 Oculink SFF-8611 interface impose on this cable?
The cable carries PCIe 4.0 x4 signals, capping throughput at the 12 Gbps rating stated for the SFF-8639 device end.
What physical clearance and power connector does the U.2 SFF-8639 end require?
The SFF-8639 plug needs a standard U.2/U.3 drive bay and a separate SATA power lead for the drive.
How is the cable installed, and which step is often missed?
Connect the SFF-8611 host plug, attach the SFF-8639 device plug, then plug the SATA power cable; forgetting the SATA power is the common error.
