SlimSAS SFF-8654 to dual OCuLink SFF-8611

This 50 cm internal cable links a backplane or storage device with a Slimline SFF-8654 8i 74-pin connector to a controller or host adapter fitted with two SFF-8611 OCuLink ports. It carries four signal channels at 24 Gbps for SAS and 8 GT/s for PCIe per channel, meeting SAS 4.0 and PCIe Gen 3/4 specifications. The compact connector and black cable assembly save space inside servers, storage arrays or workstations.

Builders with Slimline 8654 backplanes and OCuLink

Suitable for technicians who need a direct 1-to-2 breakout between a single 74-pin SlimSAS port and dual OCuLink receptacles without active electronics. Not suited for installations that require a straight-through 8654-to-8654 link or a different breakout such as 8654 to four Mini SAS HD. Buyers needing longer runs or external bulkhead mounting should look for a cable with the appropriate length and connector style.

50 cm length with 24 Gbps SAS per channel

The half-metre reach determines whether the cable spans the distance between your backplane and controller inside the chassis; measure the routing path before ordering. The 24 Gbps SAS and 8 GT/s PCIe per-channel rating sets the maximum throughput the assembly can support.

Questions about this item

What speed does the SFF-8654 8i 74-pin interface actually deliver per channel?

The cable supports 24 Gbps for SAS and 8 GT/s for PCIe per channel, meeting the SAS 4.0 and PCIe Gen3/4 specifications.

What physical clearance does the dual SFF-8611 OCuLink end need to fit inside a chassis?

The cable uses a smaller Slimline connector and 50 cm length to save device space; the dual SFF-8611 plugs require standard OCuLink port spacing on the controller or backplane.

How is this cable installed and what step do people often miss?

Connect the SFF-8654 74-pin plug to the backplane and the two SFF-8611 plugs to the controller; the common mistake is reversing the male-to-female orientation so the latches do not engage.
