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 […]

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, […]

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. […]

One year ago, VIAVI unveiled the industry’s first dual-port 1.6Tb test set at ECOC 2024, the ONE-1600, featuring live demos, 8 x 200G electrical lanes, and an OSFP1600 DR8 with optical loopback. Today, we continue to lead the 1.6Tb ecosystem with comprehensive PHY to Ethernet coverage scaling to 102Tb of test bandwidth aligned to the […]

In the rapidly evolving world of AI data centers, VIAVI Solutions is at the forefront with its innovative enhancements to the MAP testing platform. One standout feature is Enhanced Time Domain Reflectometry (TDR), a software addition to the PCT infrastructure that simplifies and accelerates fiber optic testing. What is Enhanced TDR? Enhanced TDR is designed […]

As digital technologies advance and consumer demands shift, the global telecommunications industry is rapidly undergoing a transformation. Faster networks and lower latencies are required to support emerging technologies such as IoT networks/systems, AI and cloud computing. As such, telcos are evolving to resemble technology companies, with a focus that extends beyond what a traditional telco […]

Since VIAVI announced its ONE LabPro™ ONE-1600, dual OSFP1600 test system at ECOC 2024, we have been very busy supporting the ecosystem by developing and validating 1.6Tb/s modules around the world. Decades of compounding experience – from 10Gb/s to 1.6Tb/s today – has given VIAVI a solid foundation and several unique applications. We always learn […]
