Viavi has solidified its position as a diversified AI and defense technology leader, successfully decoupling from cyclical telecom spending. The data center ecosystem now drives 50% of NSE revenue, fueled by 1.6T, CPO, and OCS adoption, with CPO revenues accelerating. Strong operational leverage and completed Spirent integration are accelerating margin expansion and revenue growth, with $500M+ quarters now expected in calendar 2027. (Updated: 2026-10-17)
The AI-driven data center ecosystem is Viavi's primary growth engine, now comprising approximately 50% of NSE revenue. Demand for lab, production, and field instruments is robust, driven by hyperscaler build-outs and the rapid ramp of 1.6T optical modules, with CPO revenues starting and accelerating in Q1 FY27. The launch of Ultra Ethernet Transport solutions further extends Viavi's leadership in this high-growth market.
Viavi's Aerospace and Defense segment continues to scale rapidly, with Positioning, Navigation, and Timing (PNT) solutions identified as a multiyear growth driver. This high-margin business provides a stable, non-cyclical revenue stream, complementing the high-growth data center segment and further diversifying Viavi's overall revenue mix away from traditional telecom.
Management has demonstrated strong operational execution, achieving a 24% operating margin in Q4 FY26 and guiding to 27.1% for Q1 FY27, with expectations for mid-to-high 20% margins soon. The Spirent integration is complete and ahead of schedule, realizing synergies. This efficiency, coupled with strong revenue momentum, is pulling forward the expectation for $500 million-plus revenue quarters to calendar 2027.
Despite current strong demand, the data center ecosystem remains susceptible to hyperscaler digestion cycles. If major cloud providers pause or slow their capital expenditures following initial AI build-outs, Viavi's heavy reliance on this segment (50% of NSE revenue) could expose the company to significant revenue swings and impact growth projections.
While Spirent integration is complete, the overall market for network testing and security remains competitive, with potential for intense pricing pressure or new entrants. Although the previous 'timing' issues are resolved, sustained growth in Spirent's product lines will depend on consistent demand from enterprise and government customers, which can be lumpy.
Legacy business segments, particularly wireless/RAN testing, continue to show anemic, albeit stable, customer demand, acting as a drag on overall growth. While OSP's 3D sensing and anti-counterfeiting products showed strength, the segment's inherent cyclicality tied to smartphone adoption and government banknote redesigns could still introduce revenue volatility.
