More About VIAVI
VIAVI Solutions focuses on test, monitoring, and assurance technologies that are used across telecom, enterprise IT, and public sector network environments. Its portfolio covers fiber, cable, and wireless access networks through to core, data center, and cloud infrastructure, with products designed for field technicians, network operations centers (NOCs), and lab or manufacturing engineers.
In the network test and measurement domain, VIAVI supplies portable and modular instruments (network test and measurement) that support Ethernet, fiber optics, cable, and wireless technologies. These tools commonly interact with optical fiber standards, Ethernet protocols, and transport technologies used in carrier and enterprise backbones. Field solutions are used for tasks such as fiber characterization, optical power measurement, and validation of Service Level Agreements (SLAs) during deployment or troubleshooting.
For service assurance and network visibility, VIAVI provides software-centric platforms (service assurance / observability) that ingest packet, flow, and telemetry data from multi-domain networks, including physical infrastructure, virtualized network functions, and cloud resources. These systems are typically integrated with Network Operations Center (NOC) workflows to support fault management, performance analytics, and user experience monitoring. They align with architectures that use probes, collectors, and analytics engines to give operations teams end-to-end visibility across IP, Multiprotocol Label Switching (MPLS), mobile, and broadband environments.
In lab, production, and manufacturing settings, VIAVI offers test systems (lab and production test) that are used by network equipment manufacturers and component vendors to validate products before deployment. These systems support conformance, functional, and performance testing against industry protocols and interface specifications used in routing, switching, optical transport, and wireless access equipment.
Beyond telecom and IT, VIAVI operates in optical security and authentication (optical security), supplying materials and technologies used in banknotes, identification documents, and brand protection labels. These products are based on optical coatings and related materials science that enable machine-readable and human-recognizable security features.
Enterprises and service providers typically deploy VIAVI offerings within broader network operations frameworks that may include IT service management tools, trouble-ticketing systems, and security monitoring platforms. VIAVI’s solutions are often categorized in enterprise directories under network test and measurement, service assurance and observability, optical networking tools, and lab and production test systems, with additional categorization in optical security for currency and document protection use cases.
