The lack of strength of GNSS signals at the end of their journey from a satellite makes them highly prone to interference. The RF power level of a GPS or Galileo signal, for instance, is below the thermal signal floor by the time it reaches the earth. Interference techniques are being used widely, especially around […]
By 2030, almost 40% of wireless traffic will be AI traffic. The question every operator will face is: who tests the AI, and with what data? VIAVI turned 100 in 2023, marking a century of leadership in test and measurement, from the optics that move data through fiber to the wireless instruments that have measured […]
Hollow core fiber (HCF) is rapidly transitioning from lab research into field trials and early operational deployments. Its ability to guide light through a predominantly air‑filled core rather than solid glass enables tangible performance gains, most notably lower attenuation, reduced latency, and less signal distortion. These properties make HCF especially attractive, particularly for data center […]
As cloud, AI, and high-performance compute environments scale, the physical media inside the data center is undergoing a fundamental shift. Traditional duplex fiber architectures are being rapidly replaced by multifiber connectivity, driven by higher speeds, denser architectures, and the relentless growth of east-west traffic. While this shift unlocks massive performance gains, it also introduces new […]
The workloads of today’s artificial intelligence (AI) applications place extraordinary demands on the quality and reliability of high-speed networks. That is true during AI training or inferencing to respond to the growing number of users issuing complex prompts, but the two broad usage models have significantly different requirements than the network connecting the thousands of […]
Scale is a critical factor for AI. The growth in the size of models used for generative AI over the past decade is just one aspect of the effects of scaling. Now, as AI embeds in everyday life, the capacity needed for successful deployment is challenging networking and computing architectures. Whether training AI models or […]
2026 is shaping up to be a defining year for the optical networking industry, as evident at OFC. Notably, it highlighted the ongoing convergence of multiple technologies that, when coupled with the rise of AI-native networks, means traditional throughput tests are no longer sufficient to guarantee a network can handle synchronized AI compute efficiently, reliably, […]
The 2026 Quantum Networks Summit offered a rare window into how organisations are approaching the shift toward post‑quantum security. While the industry buzzes with theory and long‑term planning, customers at the event were focused on something far more immediate: how these technologies will actually behave in their networks. Across conversations with operators, integrators, labs, and […]
Right now – in a network operations center (NOC) near you, the team is hard at work monitoring network performance and availability, performing routine maintenance, and responding to incidents. Meanwhile, in the adjoining security operations center (SOC), dedicated security professionals are continuously monitoring systems, networks, and applications for malicious activities and indicators of compromise (IoCs). […]
The divide between NetOps and SecOps teams was once thought to be necessary and unavoidable, with the former focusing their time and attention on network uptime, performance, and reliability, while the latter kept a close eye on cybersecurity threats, data breaches, and indicators of compromise (IoC). For decades, these siloed teams leveraged similar data sets […]
