Black 0.5m cable with SFF8654 38pin and SFF8643 connectors

SMUGDESK

SMUGDESK 0.5m SFF8654 4i 38Pin to SFF8643 SAS Cable

SKU CH-99FZ-KCDP1

Connects SFF8654 Slimline SAS 4i to SFF8643 Mini SAS HD ports with 12Gbps bandwidth over .5m of 30AWG copper for dense server routing

  • Bridges SFF8654 Slimline SAS to SFF8643 Mini SAS HD ports
  • Supports PCIe 4.0 and SAS 3.0 standards for 12Gbps data transfer
  • 30AWG pure copper conductors minimise signal loss and impedance
  • Black server-grade shielding provides strong anti-interference performance
  • 5m compact length enables tidy internal routing in rack servers

SFF8654 4i to SFF8643 Cable

This 0.5m internal cable connects SFF8654 4i 38pin Slimline SAS ports to SFF8643 Mini SAS HD interfaces. It serves administrators building or servicing highdensity storage arrays and RAID controllers in enterprise environments. The link supports PCIe 4.0 and SAS 3.0 standards at 12Gbps bandwidth.

30AWG Copper with Shielded Build

Highgrade 30AWG pure copper conductors provide low impedance and minimal signal attenuation across the run. Black servergrade shielding wraps the assembly to suppress electromagnetic interference inside crowded chassis. The direct interconnect design eliminates intermediate adapters for a cleaner signal path.

Passive Operation in Dense Racks

As a passive copper assembly it draws no power and adds no acoustic noise to the system. The 0.5m length keeps excess slack out of 2U and 4U rackmount servers, aiding airflow through backplanes. Stable 12Gbps throughput is maintained under normal operating temperatures without active cooling.
