Two black SFF-8643 SAS cables, 1 m each, with sideband connectors

10Gtek

10Gtek SFF-8643 to SFF-8643 SAS cable 1 m 3.3 ft 12 Gbps 100 Ohm 2 pack

SKU CH-NAF2-BTW38

Connects internal SAS HD SFF-8643 devices at up to 12 Gbps with 100-Ohm impedance over 1 metre, supplied as a two-pack

  • Connector count2
  • Product typeCable Connectors
  • Product colorBlack
  • Overall length3.28 ft (1 m)

Length 3.28 ft.

  • 12 Gbps data rate supports SAS 3.0 speeds
  • 100 Ohm impedance maintains signal integrity
  • Sideband wiring included for full functionality
  • 1 m (3.3 ft) length fits standard chassis
  • Pack of two cables for dual connections

Internal SAS HD cable pair

This two-pack supplies SFF-8643 to SFF-8643 cables for internal SAS 2.1 and 3.0 links. Each assembly runs 1 metre (3.3 ft) with 100-ohm impedance and 30 AWG conductors. The sideband wiring is included for enclosure management traffic.

Suits dual-controller shelves or JBOD expansion

Builders wiring a single controller to one backplane, or anyone needing external multilane links, will not use these internal assemblies. The fixed 1-metre length also limits runs that require longer reach between chassis.

12 Gbps per lane over SFF-8643

The cable is specified for 12.00 Gbps data rates on SAS 3.0 while remaining compliant with SAS 2.1 at 6 Gbps. This single rate ceiling decides whether the link meets your controller and backplane requirements.

Questions about this item

How do I install the SFF-8643 connectors and what step is often missed?

Align each SFF-8643 plug with the Mini SAS HD port and push until the latch clicks; the step often missed is confirming the sideband pins are fully seated for 12.00 Gb/s operation.

What maintenance or replacement will this cable need later?

The 30 AWG conductors and 100 Ohm impedance are rated for the life of the chassis; replace only if the latch breaks or the cable is kinked beyond the 3.28 ft length.

What limit appears first under sustained 12 Gbps use?

The 100 Ohm impedance and 30 AWG wire gauge set the signal integrity ceiling; beyond the rated 12.00 Gb/s the eye diagram closes before any thermal limit is reached.
