Connection density
This 0.5 m passive copper cable carries two SFF-8644 Mini SAS HD connectors in a male-to-male arrangement. Each channel supports up to 12 Gbps with a controlled 100-ohm impedance. The high-density interface suits NVMe enclosures, SAN equipment and JBOD arrays where rack space is tight.
Signal integrity
The assembly follows the SAS 2.1 and proposed SAS 3.0 electrical specifications for 6 G and 12 G operation. An on-board EEPROM lets the host identify cable type and length automatically. Improved latch geometry lowers insertion force while raising retention force for a secure fit.
Build integration
The reduced connector footprint leaves extra room on low-profile PCIe cards that can accept four 4x Mini SAS HD ports instead of two legacy Mini SAS ports. The 26-conductor passive design needs no external power and adds no active heat or noise to the chassis.
Not for fiber runs
Buyers who need longer reach than 0.5 m or optical isolation for electrically noisy environments must choose an active optical cable instead. This copper assembly is limited to short intra-rack links and cannot span between racks or rooms.

Questions about this item
How do I plug the SFF-8644 connectors into my NVMe enclosure and avoid damaging the latch?
Align the male SFF-8644 ends with the Mini SAS HD ports, push straight in until the improved latch clicks, and pull the release tab — not the cable — to unplug.
Will the 100-ohm copper assembly need any periodic re-termination or firmware updates?
No, the passive cable has no active components; the EEPROM signature is read-only and requires no maintenance.
At what point does the 0.5-metre length hit its signal-integrity limit under continuous 12 Gbps traffic?
The 100-ohm impedance and shielding are rated for 12 Gbps per channel at this length; sustained loads stay within spec without added equalisation.
