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 […]
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, […]
Data center architectures are rapidly evolving, with 2026 marking a pivotal inflection point toward AI-native networks. This shift is redefining workload characteristics, driven by distributed AI/ML training, large-scale inference, and high-performance computing (HPC) operating across the fabric. As these demands intensify, data center infrastructure must evolve in lockstep to deliver the scale, performance, and reliability […]
Test and measurement for critical infrastructure is entering a new phase. In 2026, changes that have been emerging in the background are very much set to shift to become front of mind. These changes relate to security, AI, photonics, and sensing. While all could be said to be related but evolving independently, they are now […]
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. […]
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 […]
224G SERDES is a high-speed interface technology that underpins next-generation 1.6Tb links. Getting 224G signals from the ASIC to the interconnect and beyond remains a key challenge for the deployment and scaling of 1.6Tb. Each 1.6Tb link uses 8 lanes of 224G signaling. For Ethernet, this actually runs at 212.5 Gb/s, which includes some overhead […]
