Slimline SAS SFF-8654 8i to dual 4i breakout cable 1 metre

SMUGDESK

SMUGDESK SFF8654 8i to Dual SFF8654 4i SAS Cable 1M

SKU CH-DGT2-B3ATZ

Splits one SFF8654 8i port into two SFF8654 4i ports with anti-misplug protection, 32AWG copper, 10ohm impedance and 12Gbps SAS speed for NVMe storage

  • Splits one SFF8654 8i port into two SFF8654 4i ports for flexible storage expansion
  • Anti-misplug housing prevents reverse insertion to protect server ports and hardware
  • 10ohm impedance-matched 32AWG copper delivers stable 12Gbps signal transmission for NVMe SSDs
  • Shielded construction reduces crosstalk and electromagnetic interference for reliable long-term operation
  • 1meter length enables flexible internal routing in rackmount servers and high-density workstations

Breakout Cable for Server Storage

The SMUGDESK SFF8654 8i to Dual SFF8654 4i cable splits a single Slimline SAS port into two separate connections. It enables flexible storage expansion inside rackmount servers, RAID controllers and high-density workstations. The one-metre length supports standard internal chassis routing. It is built for enterprise environments that need reliable NVMe SSD connectivity.

12Gbps Signal Limits and Impedance

The cable is rated for 12Gbps bandwidth using 32AWG pure copper conductors with 10ohm impedance matching. Shielded construction reduces crosstalk and electromagnetic interference to maintain signal integrity. Performance depends on the host controller and drive capabilities supporting the same standard. Longer runs or higher speeds than specified are not supported by this assembly.

Anti-Misplug Housing and Daily Handling

A built-in anti-misplug structure prevents reverse insertion, protecting sensitive server ports and hardware from physical damage. The breakout design adds two connectors from one, so cable management must accommodate both branches within tight chassis spaces. Durable shielding withstands repeated mating cycles in production deployments. Installers should verify port orientation before applying force.

Questions about this item

Should I use the single SFF8654 8i end or the dual SFF8654 4i ends for my controller?

The cable splits one SFF8654 8i port into two SFF8654 4i ports, so connect the 8i side to your controller and the 4i ends to your drives or backplane.

Will the 12Gbps rating deliver full speed to my NVMe SSDs?

The 10ohm impedance-matched 32AWG copper wire is built for stable 12Gbps signal transmission, supporting NVMe SSD bandwidth through the SAS interface.

What SAS standard does the SFF8654 connector cap at in practice?

The SFF8654 connectors on this cable are designed for 12Gbps SAS signalling, matching the 12Gbps high-speed rating of the assembly.
