SMUGDESK OCuLink SFF8611 to SAS SFF8644 12Gbps .5m Cable

SKU CH-TMG3-WCSBB

Connects OCuLink SFF8611 to SAS SFF8644 at 12Gbps for RAID and storage expansion in a .5m shielded cable

  • Connects OCuLink SFF8611 to SAS SFF8644 for flexible server builds
  • Delivers 12Gbps bandwidth for enterprise storage workloads
  • Short .5m length enables clean routing in tight chassis
  • Works with RAID controllers and storage arrays for expansion
  • Low-loss conductors and shielding ensure reliable long-term data transfer

OCuLink SFF8611 to SAS SFF8644 Cable

This cable bridges an OCuLink SFF8611 4i port to a SAS HD SFF8644 4i connector, enabling direct links between RAID controllers, enterprise SSDs and storage arrays. It suits system builders who need a short internal run in dense workstations or server chassis.

Bandwidth and Length Constraints

The link runs at 12Gbps, so the channel is limited by the SAS interface specification rather than the OCuLink side. At .5 metres the cable is too short for full-rack spans and cannot reach between widely separated enclosures.

Installation Notes

The pre-terminated 4i ends plug straight into matching headers without tools, but the stiff shielding demands careful routing in tight backplanes. Misaligned latch engagement is the most common cause of intermittent detection.

Questions about this item

Which version of the SMUGDESK cable should I pick for my server?

Choose the .5 meter length with SFF8611 to SFF8644 connectors when your chassis needs a short internal run between an OCuLink port and a SAS backplane.

What does the 12Gbps rating mean once the cable is installed?

It lets each lane transfer data at up to 12 gigabits per second between a RAID controller and SAS storage devices.

How does the SAS interface limit real-world throughput?

The SAS HD SFF8644 4i connector caps each lane at 12Gbps, so total bandwidth depends on how many lanes your controller and backplane actually use.
