80cm black braided SAS cable SFF-8654 74Pin to SFF-8643 36Pin

SMUGDESK

SMUGDESK SAS 4.0 80cm SFF-8654 8i 74Pin to SFF-8643 8i 36Pin sas cable

SKU CH-6GNG-1Y2BJ

An 80 cm SAS 4.0 cable connects a low-profile SFF-8654 8i 74-pin port to an SFF-8643 8i 36-pin backplane at 24 Gbps per lane

  • 24 Gbps per lane bandwidth with SAS 4.0 compliance
  • Low-profile SFF-8654 connector saves space in compact servers
  • Gold-plated 74-pin to 36-pin contacts ensure stable 24/7 operation
  • 80 cm braided shielding jacket blocks EMI for clean signal integrity
  • Designed for RAID HBA cards, backplanes and NAS expansion

Server Storage Adapter Cable

This 80-centimetre SAS 4.0 adapter cable connects a Slimline SFF-8654 8i 74Pin host port to an SFF-8643 8i 36Pin backplane. It targets administrators who need a direct link between modern RAID controllers or HBA cards and high-density drive enclosures. The fixed length suits rackmount chassis where cable routing is predictable and service loops are managed by the cabinet design.

Low Profile Slimline SFF-8654 8i Connector

The low-profile SFF-8654 8i end reduces vertical clearance inside half-height server slots and dense backplanes. Gold-plated 74-pin to 36-pin contacts lower impedance and resist vibration-induced signal loss in continuously operating systems. A dense braided shield wraps the full harness to suppress electromagnetic interference from adjacent power modules and maintain signal integrity across all eight lanes.

24Gbps Per Lane Sustained Throughput

Built to the SAS 4.0 and PCIe 4.0 specifications, the cable supports 24Gbps per lane during extended heavy-load read and write cycles across multiple HDDs and SSDs. The thickened elastic contacts prevent dropout and transmission errors when chassis temperatures rise under continuous duty. It is not suited for external connections or configurations requiring longer reach than the fixed 80cm assembly allows.

Questions about this item

What is the maximum single-lane bandwidth this SAS 4.0 cable supports?

The cable complies with SAS 4.0 and PCIe 4.0 standards, delivering up to 24Gbps per lane for ultra-high-speed storage traffic.

How does the braided shielding affect signal quality during continuous heavy loads?

The dense black braided jacket provides anti-EMI protection that blocks crosstalk from power modules, preserving signal integrity during sustained multi-drive read and write operations.

Which controller or backplane connectors must be present for this cable to function?

One end requires an SFF-8654 8i 74-pin low-profile port and the other an SFF-8643 8i 36-pin HD Mini SAS port, both male interfaces on the cable.
