Teledyne LeCroy and Spirent join forces on PAM4 generation and analysis

November 17, 2017 // By Jean-Pierre Joosting
Teledyne LeCroy and Spirent Communications have announced the first Ethernet generation and test system for developers of PAM4 networks.

The partners have created the QSFP28 to SFP56 single w/PTAP adapter, an exclusive PAM4 adapter allowing design and test engineers the ability to source, synchronize, capture, and analyze PAM4 signaling for emerging IEEE 802.3cd-based applications.

PAM4 signaling enables higher throughput Ethernet connections to support the growing need for data storage and communications speeds. These higher signaling rates require increased attention to intricacies of establishing and maintaining robust and healthy link connections. Spirent TestCenter generates IEEE compliant 50GbE traffic for exercising these new Ethernet links. Teledyne LeCroy's SierraNet analyzer captures and decodes the traffic which is ported via the QSFP28 to SFP56 single w/PTAP adapter module.

Early adopters of the IEEE 802.3cd for 50GbE Ethernet transactions need generation and analysis tools to ensure their designs are specification compliant. Teledyne LeCroy and Spirent offer best-in-class systems to ensure Network Equipment Manufacturers (NEMs) new products meet customer expectations of operation and conformance. The NEMs reliance on the Test and Measurement community is increasing, as homegrown tools are not up to the task.
