A new line of Mini-SAS cable assemblies comes in the form of high-performance, cost-effective cabling solutions for high-speed serial buses supporting 4X Serial Attached SCSI (SAS) architectures. The copper cables from Tyco Electronics are designed to be fully compliant with 3 Gbit/s SAS and 6 Gbit/s SAS protocols. Target product applications include mass storage systems, storage area networks and switches, servers and routers.

The Mini-SAS cable assemblies were recently submitted for testing at the SCSI Trade Association (STA)-sponsored 11th Serial Attached SCSI (SAS) Plugfest, held in October 2010 at the University of New Hampshire InterOperability Laboratory (UNH-IOL). Plugfest was an event held to validate the latest SAS 2.1 specification, which underlies the 6 Gbit/s SAS generation in supporting equipment such as servers, storage, switches, etc. as well as cable assemblies.

At the event, Tyco tested its Mini-SAS external cables within the large system build included at Plugfest. Tyco tested its standard 24 AWG, 10m cable and raised the bar by also testing longer length cables (30 AWG at 5.5m, 28 AWG at 7m and 26 AWG at 8.5m) with 6 Gbit/s SAS signaling speeds—demonstrating its wide breadth of customized cable assembly solutions.

Final test results concluded that no bit errors were detected, which indicates that Tyco Mini-SAS cables perform without dropped data for system builders using the 6 Gbit/s SAS technology. Prior to the event, internal S-parameter and near-end-crosstalk tests were conducted on the cable assemblies to meet the requirements for 6 Gbit/s SAS specifications.
