Ethernet analysis software helps test a range of speeds in cloud systems

15 September 2020

Teledyne LeCroy has introduced a complete test and network validation software suite that offers Ethernet protocol analysis for a full range of speeds.

The SierraNet M648 Ethernet and Fiber Channel Protocol Test System supports the complete analysis of IEEE 802.3cd based 200GbE pulse amplitude modulation (PAM4) Ethernet links. The system includes InFusion traffic impairment tools for both NRZ and PAM4 signaling.

Cloud computing requires data centers to move vast amounts of data and use technologies such as PAM4 in the networks. SierraNet helps analyze traffic over QSFP-DD and QSFP-56 as well as SFP connections using direct attach copper, active optical cables and optical transceiver interconnects. This allows network equipment manufacturers and data center managers to test their network capabilities and identify issues that inhibit network efficiencies.

“The IEEE 802.3cd signaling and data rates are seeing accelerated adoption, and 200GbE is a key element for achieving the high-speed access to cloud and enterprise data storage,” said David Rodgers, senior product manager with Teledyne LeCroy. “With a focus on both the transport layer as well as the supporting storage protocols, the SierraNet is essential for maintaining critical networks, and to improve uptime, energy and resources.”
