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. […]
September 27 marks the 200th anniversary of public rail transport. Over the course of two centuries since the opening of the Stockton Darlington line, the world’s first commercial route, communications have been essential for rail safety. In this blog, we’re taking a look at how railway communications have evolved over time. 1825: Flagmen on Horseback […]
Last weekend, an undersea cable in the Red Sea was cut, disrupting internet access in the Middle East and Asia. It wasn’t until three days after the cutting that it was reported that it was likely the result of commercial shipping. This isn’t the first instance. Four Red Sea cables were cut last February by […]
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 […]
Later this month, the VIAVI team will head to Washington, DC and Copenhagen for SCTE TechExpo and ECOC (European Conference on Optical Communication). In this blog, we will examine the increasing need for and the role of AI in fiber optic connector inspection, as well as highlight one of the key innovations on display at […]
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 […]
I had the opportunity to attend the ETSI Quantum Safe Cryptography Conference in Madrid recently, a gathering that brought together global leaders in cryptography, telecom, finance, and cloud to discuss the path to a quantum-safe future. The event was rich with technical insights, but more importantly, I had the chance to connect with key stakeholders […]
Digital twins — virtual models of physical systems like 6G, NTN, and 5G — make it possible to simulate, analyze, and optimize all network systems and components, including their non-terrestrial elements. This is especially useful for accelerating rollouts and identifying bottlenecks and drawbacks before they become real problems. In this two-part blog series, we will […]

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 […]
