SMUGDESK Slimline SAS SFF8654 4i 38Pin to Mini SAS HD SFF8643 Cable .5m 12Gbps 30AWG Black

SKU CH-9NAD-TXR3Q

Connects SFF8654 Slimline SAS to SFF8643 Mini SAS HD at 12Gbps using 30AWG pure copper for reliable server interconnects

  • Connects SFF8654 Slimline SAS to SFF8643 Mini SAS HD for direct server interconnection
  • Delivers 12Gbps bandwidth under PCIe 4.0 and SAS 3.0 protocols for highspeed data transfer
  • Built with 30AWG pure copper wire to reduce signal loss and crosstalk
  • Heavy duty shielding provides antiinterference performance for longterm data center operation
  • 5m short length enables clean internal routing inside compact 2U and 4U rackmount servers

Connector pairing

This internal cable links an SFF8654 4i 38Pin Slimline SAS port to an SFF8643 Mini SAS HD port. It is built for RAID controllers, enterprise storage arrays and high-density server deployments needing a direct high-speed link. The half-metre length suits tight 2U or 4U rackmount chassis where space is limited.

Sustained data handling

Compliant with PCIe 4.0 and SAS 3.0 protocols, the assembly delivers a stable 12Gbps transfer rate across all four lanes. Premium 30AWG pure copper conductors reduce signal loss, crosstalk and impedance interference during continuous heavy workloads. The construction maintains bandwidth integrity without the degradation seen in lesser cables under prolonged use.

Thermal and power profile

Heavy-duty black shielding provides anti-interference performance that keeps the link clean in electrically noisy data-centre environments. Passive operation adds no fan noise and draws no extra power beyond the signal itself. The short 0.5m run minimises resistive loss and helps maintain signal quality inside dense backplanes.

Questions about this item

Does the 30AWG pure copper construction limit heat buildup when the cable runs at 12Gbps continuously?

The 30AWG pure copper wire is designed to reduce signal loss and crosstalk, which helps maintain stable operation during sustained 12Gbps transfers.

Which controller or backplane must already have an SFF8654 4i 38Pin port for this cable to connect?

You need a device with an SFF8654 4i 38Pin Slimline SAS interface on one end and an SFF8643 Mini SAS HD port on the other.

Will the PCIe 4.0 and SAS 3.0 compliance let this cable work with older SAS 2.0 backplanes?

The cable follows PCIe 4.0 and SAS 3.0 protocols; compatibility with SAS 2.0 equipment depends on the controller and backplane specifications.
