Connector bridge for SAS backplanes

This cable pair links an SFF-8643 HD Mini SAS host port to an SFF-8087 Mini SAS backplane or expander. It serves server builders and storage integrators who need to connect newer controllers to existing 6Gbps drive enclosures. The .5 m length keeps internal routing tidy in dense chassis.

Fits between controller and drive bay

Male-to-female terminals plug directly into a RAID HBA or motherboard header on one side and a backplane or adapter on the other. Copper conductors and 100 Ohm impedance maintain signal integrity without requiring active equalisation. The thin, foldable jacket eases cable management in tight server cabinets.

Rated for 6Gbps with 12Gbps headroom

Compliant with SAS 2.1 and SAS 3.0 specifications, the assembly handles 6Gbps SAS and SATA drives today while the same part number supports 12Gbps drives when the system is upgraded. Thirty-AWG twin-axial construction limits skew at the higher rate. Buyers needing longer runs or external bulkhead connections will need a different cable.

Questions about this item

How far can I run this .5 m cable before signal loss becomes the first limit under sustained use?

The 0.5 m length and 100 Ohm impedance are designed for short internal server runs; longer distances would need active or optical cables.

Does the cable generate noticeable heat or noise when running all day at 6 Gb/s?

As a passive copper assembly it produces no noise and negligible heat; the 30 AWG conductors handle 6 Gb/s continuous traffic without thermal issues.

Which controller and backplane connectors must I already have for this SFF-8643 to SFF-8087 cable to work?

You need a controller or HBA with an SFF-8643 port and a backplane or expander with an SFF-8087 port; both ends are male-to-female.
