Teledyne LeCroy SAS analyzer addresses active optical cable, SAS connectivity management

Test and measurement specialist Teledyne LeCroy has added support of active optical cables and SAS connectivity management to the company's SAS/SATA Protocol Analyzer platform line. The new Sierra M124A SAS/SATA protocol verification platform addresses the growing use of SAS fiber-optic cable for high-speed connectivity at up to 100 m for large-scale deployments.

"This update to Teledyne LeCroy's flagship SAS and SATA analyzer platform helps support the external RAID and server OEMs that require longer reach for SAS-based storage applications," explained Michael Romm, general manager at Teledyne LeCroy's Protocol Solutions Group. "Addressing the broadest range of applications is a hallmark of the Sierra SAS/SATA test platform. The new M124A fills an important role within the 12-Gbps SAS ecosystem by allowing developers to test external storage connections that utilize active copper and active optical cables."

Meanwhile, the SAS connectivity management support addresses designs in which devices can automatically discover cabling attributes by reading an embedded EEPROM within the Mini SASHD (SFF-8644) external cable housing. The Sierra M124A analyzer can also read the embedded EEPROM data within these cables and display such characteristics as length, width, part number, and transmitter technology.

Teledyne LeCroy asserts the Sierra M124A supports the use of optical cables in all configurations including analyzer, jammer, and traffic generator modes. The system is available for immediate shipment.
