As hyperscale facilities shift toward 1.6T Ethernet and prepare for 3.2T, the methodology for network testing must be upgraded. Validation of High-Speed Ethernet (HSE) and data center fabrics needs to take place across all layers, from OSI Layer 0 (the medium) to 7 (the application, including security). This means that we need to not only […]
Advances are taking place across a wide range of technologies. At ECOC 2026, we saw leaps forward in high-speed Ethernet (HSE), co-packaged optics (CPO) and silicon photonics (SiPh), along with fiber density, multifiber technologies, and alternative designs such as hollow-core fiber (HCF), alongside advances in peripheral but critical systems like quantum security. This is driving […]
If there is one aspect of AI that challenges high-bandwidth networking more than any other, it is training. However, with the growth of applications that depend on inference performance, inference is quickly catching up and placing even greater strain on the network. Compounding this are rising usage volumes, test-time scaling, mixture-of-experts architectures, and the use […]
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, […]
Over the past 18 months, the VIAVI ONE LabPro® ONE-1600 has supported customers that are bringing 1.6Tb OSFP 1600 modules to market. Challenges initially focused on PHY layer and 224G SERDES, but we now move into a more rigorous, standards-backed phase as advanced features such as APSU/ILT, inner FEC, and CMIS all must be developed, […]
As VIAVI continues to lead and support the 1.6Tb ecosystem, we now see a distinct transition from the first generation ‘can we build it?’ to the 2nd and even 3rd generation modules with the right performance and power to allow massive 1.6Tb systems deployment at scale. This is further enabled by the emergence of 102Tb switch silicon […]
Artificial intelligence is everywhere, from the smart assistant in your phone to the massive language models (LLMs) creating content online. LLMs like GPT-5, LLAMA-4 or Gemini 2.5 are not just larger versions of their predecessors; using Mixture-of-Experts (MoE) architecture, they’re on an entirely new scale, trained on petabytes of data with arguably trillions of parameters. […]
Ultra Ethernet is here. With UE 1.0 released, the focus shifts to testing and compliance. Learn how the first public UET test and evolving assurance approaches are enabling performance, interoperability, future-ready infrastructure for AI and HPC networks. After intense and dedicated work, the Ultra Ethernet Consortium (UEC) has released its highly anticipated UE Specification 1.0 to meet workload requirements […]
Businesses must embrace a new reality with agility that can transform operations, with security a top priority. SASE (secure access service edge) can help. In this sequel blog, we share the market drivers, business benefits SASE delivers, and related use cases. Employees around the world have decided they’d like to work from home, thank you […]
