SMUGDESK 40cm PCIe 4.0 Slimline SAS Splitter Cable SFF-8654 8I 74Pin to Dual SFF-8654 4I 38Pin

SKU CH-MJCV-S30EE

Splits one 74-pin SFF-8654 8I port into two 38-pin SFF-8654 4I channels for dual NVMe or SAS paths at PCIe 4.0 24Gbps per lane.

  • PCIe 4.0 & SAS 4.0 compliant for 24Gbps lane speed
  • Single 74Pin SFF-8654 8I splits to dual 38Pin SFF-8654 4I channels
  • 40cm length keeps internal routing tidy in 1U/2U servers
  • Multi-layer braided shielding suppresses crosstalk for stable signal integrity
  • Latch-lock gold-plated connectors resist oxidation and vibration loosening

Purpose-built splitter cable

This 40cm Slimline SAS splitter divides a single SFF-8654 8I 74Pin port into two independent SFF-8654 4I 38Pin channels. It targets administrators expanding NVMe SSD backplanes inside 1U or 2U rack servers and high-performance workstations. The cable carries PCIe 4.0 and SAS 4.0 signals at up to 24Gbps per lane for lossless transmission.

Verify controller and backplane ports

Confirm your storage controller exposes an SFF-8654 8I 74Pin connector and that each target backplane or U.3 expansion module presents an SFF-8654 4I 38Pin receptacle. Check that the 40cm length suits the internal routing distance between the controller card and both drive cages. Ensure the system firmware supports bifurcation of the 8-lane link into two 4-lane paths.

Fits dense server chassis

The compact 40cm design keeps routing tidy inside shallow rack enclosures while the latch-lock gold-plated connectors resist vibration-induced disconnection. Multi-layer braided shielding suppresses crosstalk to maintain signal integrity across both channels. This cable frees a second controller port or HBA slot by consolidating two backplanes onto one 8-lane interface.

Questions about this item

What comes in the box and do I need any extra brackets or screws?

The package includes one 40cm splitter cable with a 74Pin SFF-8654 8I connector on one end and two 38Pin SFF-8654 4I connectors on the other. Mounting hardware is not included.

How do I choose between the 8I and 4I ends when connecting my backplane?

The single 8I 74Pin end plugs into the storage controller port; the dual 4I 38Pin ends each connect to a separate NVMe SSD backplane or U.3 expansion module.

What does the 24Gbps per lane rating mean for real NVMe SSD throughput?

Each of the two 4-lane paths supports up to 24Gbps per lane under PCIe 4.0 and SAS 4.0 specs, giving high-bandwidth links for NVMe drives.
