FEC for Ethernet: A New Path to Flexibility

Developers can experiment with proprietary FEC while retaining compatibility with Ethernet standards due to where the “extender sublayer," (CDXS) sits, giving hardware designers more freedom to experiment with error-correcting codes. Learn more about FEC and how Spirent’s 400/200/100/50GbE quad speed-test modules were first to market, and have been designed to support the mandatory FEC/PCS IEEE requirements.

PAM4: The New Modulation Standard for High-Speed Ethernet

In early 2017, Spirent launched the first dedicated test system for 200G, based on the use of 4x50GbE PAM4 technology. Longer term, knowledge of PAM4 will be important for PHY-to-MAC emulation in any Spirent service-provider tool. Test traditional Ethernet Carrier Ethernet and be ready as future IEEE standards emerge. Read our white paper to learn more about PAM4.

Performance Testing BroadR-Reach Automotive Ethernet

As vehicle manufacturers begin to explore the opportunities offered by OABR, they will face new performance testing challenges that present a step-change away from existing performance testing regimes for legacy technologies such as CAN Bus, LIN, MOST and FlexRay.

This white paper—one of a series on different aspects of BroadR-Reach testing—is intended to give automotive developers a rapid introduction to Ethernet/IP performance testing, with specific focus on aspects which are unusual or particular to in-vehicle networks and OABR.

WP Multi-AP Performance Testing

This solution brief explains how to test the throughput performance of a multi-AP system using Spirent TestCenter including the focus on features such as reliable inter-AP Wi-Fi RF connections, maximum throughput, Band Steering and client steering. Starting with some basic information needed to understand multi-AP networking technology and design, this paper will then detail how to setup test beds to validate the throughput performance gain from various multi-AP networking configurations.
