HD SAS internal cable assemblies feature twin axial variants

FCI and 3M has announced the availability of the SFF 8643 mini multilane internal cable assemblies for SAS HD connections from FCI, which feature the twin axial cable SL8800 series from 3M. The SFF 8643 assemblies from FCI support SAS 2.1 standard at 6Gbps data rate, and are fully compliant with the upcoming SAS 3.0 specification, which increases data rate up to 12Gbps. These cable assemblies are ideal for system applications requiring high density routing in tight spaces, or where restricted air flow is a concern.

“The cable's mechanical advantages allow FCI the ability to offer cables that can be bent at a 90-degree angle during routing without any signal degradation,” noted Jim David, global product manager at FCI.

FCI’s internal miniSAS HD cables will be offered in both the 4x (4 channel) and 8x (8 channel) versions, and will include standard sideband signaling. In addition to the internal cables, FCI also offers mating internal miniSAS HD board connectors as well as a complete line of miniSAS HD external board connector systems and external cable assemblies both of which are fully SFF-8644 compliant.

The twin axial cable SL8800 series from 3M is suited for paddle card terminated cable assemblies. Now available in various two, four, and five differential pairs 100ohm 30AWG versions, the SL8800 series cable is the optimum solution for space-constrained systems. This internal cable is extremely thin, very flexible and can even be folded with minimal loss or performance impact. The low profile nature of the cable also presents minimal obstruction to airflow, providing potential power savings to designers. The SL8800 series cable is extremely high bandwidth, demonstrating virtually no resonance or discontinuities up to 42GHz. Depending on length, attenuation requirements and termination, applications of up to 25Gbps can be implemented.

Current popular applications supported by SL8800 Series Cable are MiniSAS SFF-8087 and SFF-8088, MiniSAS HD SFF 8643, PCI Express implemented on SFF 8087, and SATA assemblies.
