Teledyne LeCroy Announces First-to-Market Protocol Analyzer for Testing PAM4 based Network and Cloud Storage Products



Milpitas, Calif., August 6, 2019 – Teledyne LeCroy, Inc., the worldwide leader in protocol test solutions and a business unit of Teledyne Technologies Incorporated (NYSE:TDY), has announced the SierraNet M648 protocol analysis and traffic impairment system, the first-to-market protocol analyzer for 4 level Pulse Amplitude Modulation (PAM4) 50G Ethernet and 64G Fibre Channel interconnections. The SierraNet M648 includes a traffic impairment system that precisely introduces timing or syntax errors into network and cloud communication, allowing developers to pretest errors and debug products prior to launch.

Data in the cloud and in data centers are moving in increasing magnitude and at unprecedented speeds. As a result, capturing data is becoming more difficult for network and storage companies, which need solutions to test devices at the highest possible rates. The SierraNet M648 allows companies to test new storage products across the widest possible range of configurations and speeds over both Fibre channels and Ethernet.

“The success of new Fibre Channel technologies, and the deployment of specification compliant products, relies on the ability of the test and measurement community to provide appropriate tools and services across the ecosystem," said Chris Lyon, Fibre Channel Industry Association Chairman. “We are pleased to know companies such as Teledyne LeCroy are continuing their commitment to the global marketplace and supporting 64Gb Fibre Channel fabrics and applications."

“As the first-ever protocol analysis and traffic impairment system to test products at PAM4 50Gb Ethernet and 64Gb Fibre channel speeds, the SierraNet M648 is a major breakthrough for designers and integrators of network and cloud systems," said Michael Romm, General Manager for Teledyne LeCroy Protocol Solutions Group. “Storage devices are communicating at unprecedented speeds, and the SierraNet M648 enables engineers to te st products at the highest rates possible and avoid corrupted or lost data. The Sierra M648 is another milestone for Teledyne LeCroy as we continue our industry leadership in protocol analysis."
