PCI-E 5.0 SAS extender cable

This cable connects a SAS SFF-8654 MCIO 8i 74-pin male connector to a SFF-8654 4i 38-pin male connector. It is designed for PCI-E 5.0 signalling to support high-speed data transfer in servers and workstations. The 50 cm braided construction provides durability for demanding environments. Plug-and-play installation with labelled connectors simplifies setup.

Suits builders extending MCIO 8i to dual 4i links

Technicians who need to split an 8i wide port into two 4i connections for backplanes or RAID controllers will find this cable fits the requirement. It is not for users who require a straight 8i-to-8i extension or a different connector family such as Mini SAS HD. Buyers needing longer runs beyond 50 cm should look at alternative lengths.

Signal integrity under sustained load

The shielded, braided design maintains stable signal transmission during continuous high-throughput workloads, reducing the risk of data corruption. Secure locking connectors keep the link firm under vibration in rackmount chassis. Performance remains consistent across the full 50 cm length without the degradation seen in cheaper unshielded cables. The cable handles the bandwidth demands of PCI-E 5.0 SAS traffic without overheating or signal loss.

Questions about this item

What connector must my backplane or controller provide to plug the 74-pin end of this cable?

The cable requires an SFF-8654 MCIO 8i 74-pin female receptacle on the backplane or controller side.

Will the 38-pin connectors work with my existing SFF-8654 4i devices?

Yes, each 38-pin connector mates directly with an SFF-8654 4i port, so current drives or backplanes using that interface remain compatible.

How can I verify the link is running at PCI-E 5.0 speeds after installation?

Check the system BIOS or operating-system device tree for a PCI-E 5.0 x8 or x4 link width on the attached endpoints.
