Viavi Solutions Inc. helps data-center operators, communications providers and equipment makers check that networks and equipment work as intended, from development and manufacturing through everyday operation. These customers buy its test instruments, monitoring software and related services, including maintenance, calibration and repair. This business, Network and Service Enablement (NSE), supplies most of its revenue; customers include Cisco and Verizon. NSE also sells products that help military, aerospace and other critical infrastructure customers maintain reliable positioning, navigation and timing.
Its other business, Optical Security and Performance Products (OSP), sells materials that create visible color shifts and other effects on banknotes to help people detect counterfeits, as well as optical filters used in depth-sensing systems. VIAVI relies on SICPA to market and sell its banknote anti-counterfeiting products worldwide. OSP also gets a large share of its sales from a single customer.
Demand depends on when customers maintain, upgrade or build infrastructure, and on demand for banknote security and sensing components. Production relies on a limited group of manufacturers and suppliers, with some components available from only one or a few sources. U.S. export controls restrict the supply and support of certain VIAVI products to Huawei and affected affiliates.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
VIAVI’s results also depend on banknote-security demand and its alliance with privately held SICPA, an important sales and marketing partner for its optical security business that this list cannot show.
Keysight competes with VIAVI for sales of communications test equipment and software to network developers, manufacturers, and aerospace and defense customers. Watch demand from these customers in Keysight’s results, rather than its broader electronics business, for clues to VIAVI’s test markets.
NetScout competes with VIAVI for telecom operators’ and enterprises’ spending on tools that monitor networks and keep services working. Its service-assurance business is the relevant area to watch for VIAVI, rather than its separate cybersecurity offerings.
Ciena buys from VIAVI and sells optical networking equipment to network operators, tying both companies to capacity upgrades for cloud and AI traffic. Watch Ciena’s optical networking demand for signs of the upgrades that also require VIAVI’s optical testing tools.
RADCOM competes with VIAVI for telecom operators’ purchases of software that monitors service quality, finds faults and analyzes network performance. Demand for its RADCOM ACE offering among mobile and fixed-line operators is the clearest overlap to watch.
Crane NXT competes with VIAVI in banknote anti-counterfeiting technologies sold to government and financial-institution security markets. Watch its banknote-security business: Crane NXT uses tiny optical structures to secure physical products, while VIAVI sells pigments and inks that create visible effects.
Coherent competes with VIAVI in optical components, but its sales of data-center transceivers also track development and production that need VIAVI’s optical testing tools. Watch Coherent’s data-center and communications products for that testing-demand signal, not its industrial lasers.
Materion’s Precision Optics business competes with VIAVI’s optical security and performance business in optical coatings and precision optics. That business, rather than Materion’s metals operations, is the relevant comparison for VIAVI’s optical-product competition.
Lumentum and VIAVI serve different parts of optical-network upgrades: Lumentum sells components for customers to build into equipment and complete network systems, while VIAVI sells tools to test equipment production and fiber networks. Lumentum’s optical modules and optical circuit switches are the products to watch for this shared demand.
Nokia buys VIAVI’s network testing products, and the infrastructure it sells to telecom, enterprise, AI and cloud customers creates testing demand as it is developed and deployed. Watch Nokia’s optical and fixed-network business for upgrade activity relevant to VIAVI, whose revenue depends on when customers make infrastructure purchases.
Cisco buys VIAVI’s network testing products and sells switching and routing systems whose development and deployment require testing. Watch Cisco’s faster enterprise and data-center networking products for the investment activity that also supports VIAVI’s lab, production and field testing demand.
Fortive’s Fluke Networks competes with VIAVI in communications test instruments used by network technicians. Fluke Networks is the relevant business to watch for this overlap, not Fortive’s broader maintenance software or healthcare products.
Ericsson is a VIAVI customer, and its cellular-technology development creates demand for VIAVI’s wireless testing equipment and software. Watch Ericsson’s mobile-network development and operators’ upgrade spending, especially as weaker wireless product spending partly offset VIAVI’s fiscal 2026 growth.
Corning supplies the fiber-network ecosystem, while VIAVI sells the instruments used to install and test those networks, tying both to fiber deployment and capacity expansion. Watch Corning’s Optical Communications sales rather than its display or other materials businesses for this demand signal.
Marvell sells Ethernet and interconnect chips for data infrastructure, while VIAVI sells high-speed Ethernet and optical testing tools, tying both to faster data-center connections. Watch Marvell’s data-center business for this shared demand rather than treating all of its chip sales as a signal for VIAVI.
Applied Optoelectronics sells optical networking modules and equipment, while VIAVI sells tools to test optical links and their production, linking both to data-center optical upgrades and fiber deployment. Watch Applied Optoelectronics’ internet data-center sales separately from cable-TV sales, which also include amplifiers using radio-frequency and digital electronics rather than optical components.
Nokia Corporation earningsNOK
Nokia’s report will show demand in its optical and fixed-network businesses, where the equipment activity can support purchases of the network-testing products it buys from VIAVI.
Watch Nokia’s optical and fixed-network businesses. Growth would show that network equipment development and deployment are continuing, supporting demand for the testing products Nokia buys from VIAVI; weakness would suggest this infrastructure-spending chain is slowing and could mean less testing demand from Nokia. This is a read on a customer’s spending environment, not proof that VIAVI has won more orders.
Fortive Corporation earningsFTV
Fortive’s report will show whether Fluke Networks is finding demand for communications test instruments, the same field-test market where it competes with VIAVI.
Focus on Fluke Networks’ communications test instruments, not Fortive’s healthcare or maintenance-software businesses. Strength would show that customers are still paying for network test tools, while confirming that Fluke Networks is competing for budgets VIAVI also targets. Weakness could signal softer demand for the category, not that customers are shifting their spending to VIAVI. The result helps separate market demand from competitive pressure.
Viavi Solutions Inc. earningsThis company
VIAVI sells network testing and monitoring products through its Network and Service Enablement business, and this report will show whether demand is translating into higher segment revenue and margin.
Read Network and Service Enablement revenue alongside its operating margin. If both rise, demand for VIAVI’s network testing, monitoring and positioning products is scaling profitably; if revenue grows but margin falls, product mix or costs are absorbing some of the gain. If VIAVI breaks out revenue from acquired businesses, separate it from the rest: total growth alone does not show that underlying demand is strengthening. The question is whether VIAVI’s core network business can expand while holding its margin.
Crane NXT, Co. earningsCXT
Crane NXT’s report will show demand for banknote-security products and how a competitor is faring in the physical anti-counterfeiting market where VIAVI sells pigments and inks.
Focus on Crane NXT’s banknote-security business, not its other products. Growth would show that governments and financial institutions are still buying physical anti-counterfeiting technology, while confirming that VIAVI’s pigments and inks face an active competitor. Weakness could reflect lower purchasing, but does not show that customers have switched to VIAVI. The question is whether this market still has demand and how strong the competition is.
Materion Corporation earningsMTRN
Materion’s report will show demand for precision optics and optical coatings, where its Precision Optics business competes with VIAVI’s optical products.
Watch Materion’s Precision Optics business, not its metals operations. Growth would show that customers are still buying optical products, while confirming active competition for VIAVI; weakness could mean customer demand is softer, not that VIAVI has gained share. The report is a signal about demand and competition in the optical-products market.
Netscout Systems Inc earningsNTCT
NetScout’s report will show whether operators and enterprises are spending on service-assurance tools, a market where its software competes with VIAVI’s.
Watch NetScout’s service-assurance business, not its separate cybersecurity offerings. Strong demand would show that operators and enterprises are still buying tools to monitor networks, find faults and maintain service quality—a supportive market for VIAVI’s related software, but one in which NetScout competes for the same budgets. Weak demand would suggest a smaller market, not sales automatically shifting to VIAVI. The takeaway is about both customer spending and competition.
Lumentum Holdings Inc. earningsLITE
Lumentum’s report will show demand for optical modules and optical circuit switches used in data-center connections, equipment whose production and deployment can require VIAVI testing tools.
Watch demand for Lumentum’s optical modules and optical circuit switches, not its industrial lasers. Stronger demand would show customers developing or producing more data-center optical equipment, creating more potential need for VIAVI tools that test equipment and optical links; weaker demand could mean fewer testing opportunities along that chain. Lumentum’s results signal equipment demand, not confirmed VIAVI orders.
Ciena Corporation earningsCIEN
Ciena’s report will show whether operators are expanding optical-network capacity, a deployment cycle that also supports demand for the testing tools Ciena buys from VIAVI.
Watch demand and sales in Ciena’s optical-networking business. Strength would show that capacity upgrades for cloud and AI traffic are moving into deployment, supporting demand for the VIAVI testing tools Ciena buys; weakness would suggest slower deployments and potentially less related testing. This is evidence about a customer’s upgrade cycle, not VIAVI’s own sales.
