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 […]
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 […]
Various government directives such as the Cyber Incident Reporting for Critical Infrastructure Act of 2022 (CIRCIA) and the EU’s Critical Entities Resilience (CER) Directive mandate enhanced protection for critical infrastructure, technologies such as non-terrestrial networks (NTNs), positioning, navigation, and timing (PNT) systems, IT architecture and field communications. With such directives in effect, the security, reliability, […]
A Heritage as a Wireless Pioneer The roots of VIAVI’s wireless division – home to VIAVI Marconi Labs™ – can be traced back to Guglielmo Marconi, whose groundbreaking work laid the foundation for modern wireless transmission including radio and television broadcasting. Marconi’s wireless telegraph revolution proved that long-distance transmission could work without physical wires. His […]
