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 […]
Distributed Acoustic Sensing (DAS) has become a critical tool for monitoring and protecting infrastructure at scale. As deployments have grown, so too have the expectations to move beyond simple detection toward higher accuracy, better event identification, and fewer false alarms. This evolution has driven the adoption of phase‑based DAS, such as VIAVI’s patented true‑phase DAS, […]
As we recently announced, VIAVI and NTT DOCOMO INC. have successfully completed a joint study demonstrating AI-driven radio access network (RAN) control for next-generation 6G mobile communications. The demonstration was conducted in a simulated environment modeling multiple base stations around the Tokyo Station area. Predictions were enabled by the TeraVM AI RAN Scenario Generator (AI […]
January arrives with a different kind of energy. The decorations are packed away, our stomachs have had their pick, pace is steadier, and the attention starts turning from celebration to intention. It is also the time for fresh starts and setting the foundation for what comes next. In this spirit of renewal, TDC NET enters […]
VIAVI has always been present at major inflection points across technology – and 2025 was no different. As we continued to engage with and support the telecommunications industry around the globe, we also reinforced our leadership in the data center ecosystem, aerospace, defense, and security sectors. In this blog, we review some of the breakthroughs from […]
Networks strive to enable both high throughput and low latency. However, as the number of packets moving through a given network reaches their limit, queues start to build, with delays/ congestion introduced as a result. Congestion therefore needs to be managed but legacy mechanisms for detecting congestion rely on packet loss as a measure that […]
Advances in quantum computers mean elliptic curve cryptographic (ECC) techniques will likely be cracked in about five years. These advances not only include processing power (IBM’s Kookaburra processor is set to exceed 4,000 qubits later this year), but also in error correction. As an example, Google’s Willow is a 105 qubit computer and these error […]
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 […]
