This article details the electromagnetic simulation of low frequencies in Ansys Electronics Desktop, focusing specifically on arbitrary length transmission lines and cables with uniform cross sections. It presents two-dimensional, quasi-static field and circuit solvers as an alternative simulation method, covering the simulation workflow while highlighting the differences and benefits of using this method as opposed to using predominant full-wave field solvers. 

Arteria and Nokia achieve a groundbreaking 1 Tbps optical transmission milestone between Lyon and Toulouse, leveraging VIAVI’s cutting-edge ONE LabPro™ solutions to ensure seamless performance and scalability for future-ready connectivity.

This achievement marks an important step forward in exploring cutting-edge optical communication technologies and building communication infrastructure oriented to intelligent computing scenarios.  

Semiconductor signal conditioning and signal recovery innovations have extended data rates by managing allowable signal-to-noise ratio (SNR) at progressively higher Nyquist frequencies. We have experienced how each successive signaling technology increases the electro-mechanical design resolution needed to address the channel physics while respecting the SNR of the chips. These movements throughout the years have provided a baseline of traditional design goals that lead us to better understand today’s 224 Gbps-PAM4 physical layer requirements.

SIJ editorial advisory board member Yuriy Shlepnev offers a comparison of three ways to visualize the same s-parameter data, identifying how to get the most information from a plot.

When starting a new project, board designers are often overwhelmed when trying to choose appropriate diff pair geometry, board material, and stackup to meet high-speed serial link loss budgets. Part of the printed circuit board (PCB) interconnect challenge is modeling transmission lines accurately. 

Rosenberger has introduced the High-Speed FAKRA-Mini HFM® connector series. This new generation of automotive coaxial connectors for frequency applications up to 15 GHz is a modular system enabling fast transmission of high data rates up to 20 Gbps.
