Connectors and speed

This Vszerda active cable links an OCuLink SFF-8611 8i interface to an SFF-8654 8i interface at up to 16 Gbps. It uses tinned copper conductors and shock-resistant shielding to maintain signal quality across the 50 cm run. Both ends are male with an active latch for secure mating. The assembly is built for internal device-to-controller links in storage systems.

Who it fits and who it does not

It suits builders connecting a backplane to a RAID or HBA controller when one side presents SFF-8611 and the other SFF-8654. The cable works in either direction, so the same part covers both port layouts. It is not for external connections, nor for setups that lack a free OCuLink 8x 80-pin slot. Buyers needing a different pin count or a passive design should look elsewhere.

Deciding specification

The single figure that decides fit is the 16 Gbps data rate combined with the SFF-8611 to SFF-8654 connector pairing. If your controller and backplane match those two interfaces and can use an active 50 cm link, this cable meets the requirement. If either side uses a different connector or a lower signalling speed, the cable will not work.

Questions about this item

Do I need an OCuLink 8x 80-pin interface on my controller or backplane to plug this cable in?

Yes, the cable requires a free OCuLink 8x 80-pin interface on either the controller or the backplane to function.

Can I use this SFF-8611 to SFF-8654 cable with an older SAS backplane that has an SFF-8654 connector?

The cable connects an SFF-8611 male to an SFF-8654 male, so it will physically mate with a backplane that has an SFF-8654 socket.

How can I confirm the link is running at the rated 16 Gbps after installation?

Check the controller BIOS or operating system link-status utilities; they will report the negotiated speed for the active 8x connection.
