Overview

Viavi Solutions Inc., generally styled VIAVI Solutions, is an American technology company headquartered in Chandler, Arizona. Its principal business is the development and manufacture of equipment, software, and services used to test, validate, monitor, and manage communications networks. Its customers include telecommunications operators, cable and broadband providers, data-center operators, network-equipment manufacturers, enterprises, government organizations, and contractors responsible for building or maintaining wireless and wireline infrastructure. The company became an independent public company in August 2015, when JDS Uniphase Corporation was separated into two businesses. Viavi received the former JDSU communications test and measurement operations, while Lumentum Holdings received the communications and commercial optical products division. Viavi therefore has a corporate history that predates its current name. Its roots reach back to Uniphase, founded in 1979 in San Jose as a maker of lasers for semiconductor manufacturers and scanners. A long sequence of mergers and acquisitions eventually produced JDS Uniphase, commonly known as JDSU, from which Viavi was separated. Viavi's activities are commonly organized around network enablement, service enablement, and optical security and performance products. Network Enablement products help operators and contractors install, certify, troubleshoot, and optimize broadband, Ethernet, fiber, cable, wireless, and high-speed optical networks. Product families include T-BERD and MTS field testers, OneExpert cable and telco meters, CellAdvisor radio-frequency and base-station test equipment, and Optical Network Tester systems for high-speed optical technologies. StrataSync provides cloud-based equipment management and data collection for supported instruments. Service Enablement products address performance assurance and operational visibility after networks are deployed. EtherASSURE supports Ethernet service testing and assurance, while xSIGHT provides targeted subscriber and service analysis for mobile operators. GEOson combines network automation, geolocation information, and machine-learning techniques for the management and testing of 4G and 5G environments. The Observer portfolio includes packet capture, traffic analysis, and infrastructure-monitoring tools, including Observer Gigastor and Observer SightOps. The company's Optical Security and Performance business applies optical coatings, pigments, filters, and sensing technologies to markets beyond telecommunications. Its products include optically variable pigments used in currency security, optically variable magnetic pigments, authentication labels, ChromaFlair color-shifting coatings, thin-film optical coatings, linear variable filters, wafer-level optical components, and MicroNIR near-infrared spectrometers. These technologies support applications such as banknote anti-counterfeiting, pharmaceutical and consumer-product authentication, automotive finishes, chemical and materials analysis, aerospace, defense, and space instrumentation. Viavi optical technology has also been used in three-dimensional sensing applications, including technology associated with Microsoft's Kinect platform. Viavi's strategic position is that of a specialized infrastructure technology supplier rather than a consumer electronics brand. Its value proposition centers on independent measurement, network visibility, field portability, interoperability testing, and assurance across increasingly complex fiber, broadband, cloud, data-center, and mobile networks. The company has expanded both organically and through acquisitions, including the incorporation of network monitoring and automation capabilities. In 2024 it attempted to acquire Spirent Communications, but Keysight Technologies made a higher offer. The reference material further records that Viavi acquired Spirent's high-speed Ethernet, network security, and channel-emulation testing business from Keysight in October 2025.

History

Viavi Solutions' corporate lineage begins in 1979, when Uniphase was established in a San Jose, California garage. The early company manufactured lasers for semiconductor makers and scanner applications. Over time, Uniphase expanded through mergers and acquisitions, eventually becoming part of the larger JDS Uniphase organization, usually referred to as JDSU. The resulting business combined communications test and measurement capabilities with commercial optical technologies and served the rapidly expanding telecommunications and networking industries. A major restructuring took place in August 2015. JDSU was divided into two independent publicly traded companies. Viavi Solutions received the communications test, measurement, and assurance operations, while Lumentum Holdings received the former Communications and Commercial Optical Products division. The separation gave Viavi a more focused identity centered on network deployment, service assurance, monitoring, and specialized optical technologies. Tom Waechter stepped down as chief executive at the time of the separation, and Richard Belluzzo became interim president and chief executive officer. The newly independent company quickly broadened its software and network-visibility portfolio. In September 2015, it announced GigaStor Software Edition, designed to capture packet data from software-defined networking environments for performance analysis and forensic investigation. In February 2016, Belluzzo became chairman and Oleg Khaykin became president and chief executive officer. During the same period, Frontier Communications selected Viavi's EtherASSURE solution for network performance management, troubleshooting, and service-level agreement oversight. Viavi also developed its wireless infrastructure testing activities. In February 2016, CellAdvisor received functionality for baseband testing during cell-tower installation. The capability was intended to improve installation workflows, reduce repeat tower climbs, and support safer field operations. The company also introduced GEOson, a network automation and management tool for 4G and emerging 5G environments. GEOson incorporated technology associated with Viavi's earlier acquisitions of Reverb Networks and Arieso, reflecting the company's strategy of combining measurement hardware with software automation and location-aware network intelligence. The company's broadband and cable portfolio advanced in March 2016 when the OneExpert CATV Signal Analysis Meter gained full DOCSIS 3.1 signal-testing capability. DOCSIS 3.1 was an important technology for higher-capacity cable broadband, and field testing support allowed operators and technicians to validate newer network deployments. During that month, Viavi also announced MicroNIR near-infrared spectrometer tools for mobile, real-time, nondestructive analysis of materials and production processes. This demonstrated the continuing importance of the former optical-technology businesses alongside the core communications portfolio. Viavi expanded its ecosystem relationships in July 2016 through a partnership with Brocade. The companies connected Brocade packet-broker and session-management tools with Viavi's xSIGHT Targeted Subscriber Search technology, enabling selected subscriber traffic to be delivered for analysis. This supported Viavi's broader service-enablement proposition: helping operators move beyond basic link testing toward service, subscriber, and application-level visibility. The company's product history also reflects acquisitions made before and around its independence. The Observer Gigastor packet-capture product originated with JDSU's 2013 acquisition of Network Instruments. Observer SightOps was associated with a partnership with ScienceLogic and extended Viavi's reach into cloud and on-premises infrastructure monitoring. Together with EtherASSURE, xSIGHT, GEOson, and StrataSync, these products positioned the company across the lifecycle of network construction, activation, assurance, troubleshooting, and operational management. Outside communications, Viavi retained a substantial optical security and performance business. Its technologies include optically variable pigments and optically variable magnetic pigments for currency-security effects, authentication labels for pharmaceuticals and consumer products, ChromaFlair color-shifting coatings for automotive applications, and thin-film optical components used in sensors, three-dimensional sensing, filters, wafer-level patterning, aerospace, defense, and space systems. Viavi technology has been associated with three-dimensional sensing used in Microsoft's Kinect platform and with optical components for space missions, including a filter assembly used in the OVIRS instrument on NASA's OSIRIS-REx mission. In 2024, Viavi pursued a major expansion of its network-testing position by agreeing to a proposed acquisition of Spirent Communications at a reported value of £1 billion. The transaction did not proceed after Keysight Technologies submitted a higher offer of approximately £1.16 billion, which Spirent recommended instead. The reference material records that on October 16, 2025, Viavi acquired Spirent's high-speed Ethernet, network security, and channel-emulation testing businesses from Keysight. This later transaction, if reflected in current corporate reporting, would extend Viavi's capabilities in high-speed data-center, security, and network-emulation testing. Viavi remains an active specialist technology company whose business spans communications infrastructure assurance and advanced optical applications.
