Stifel has singled out two names within the Applied Technologies - Equipment/Test segment that it views as particularly well placed to benefit from rising demand for data infrastructure and test equipment. The firm’s review concentrates on firms with differentiated product sets, expanding addressable markets and visible demand indicators such as unusually large backlogs.
According to Stifel, sector momentum is being driven by artificial intelligence infrastructure buildouts and the scaling of advanced telecommunications systems. The firm emphasizes companies that combine distinct product advantages with growing end markets tied to wide area networks and data-center interconnects.
Ciena Corporation (CIEN)
Stifel places Ciena at the top of its sector list. The analyst note reiterates Ciena’s internal sizing of its addressable market - roughly $50 billion by 2029 - which includes wide area networks plus data-center interconnect and the scale-across layer. Stifel highlights the RLS Hyper-Rail line system as a highly differentiated offering, noting that the first deployment was co-created with a hyperscaler partner.
Stifel points to Ciena’s broad portfolio - spanning systems, interconnects including WaveLogic modems and pluggables, and software - as a reason the company could capture share as artificial intelligence increases demand across wide area networks and data centers. The firm also notes a record backlog figure of $7.7 billion as a signal of sustained demand.
The analyst raises a post-earnings question about valuation dynamics - whether future multiple expansion will reflect confidence in the total addressable market’s durability rather than be driven by any single quarter’s results.
Separately, Ciena announced it has closed a private offering of $2.875 billion in convertible senior notes. The company also named Grant Hoffman as its new Chief Supply Chain Officer.
Viavi Solutions (VIAV)
Stifel ranks Viavi Solutions second in the Applied Technologies - Equipment/Test group. The firm’s analysis expects the module test opportunity to scale more linearly with the transceiver market as 1.6T modules and systems ship. Stifel also identifies advanced packaging and legislative initiatives around fiber as potential multipliers that could create additional addressable market opportunity not currently reflected in consensus models.
In recent corporate developments, S&P Global Ratings upgraded Viavi’s rating to BB from B+ after the company repaid its term loan. Viavi also received $1.1 million in EU funding to support a 6G security project.
Market context and signals
Stifel’s sector review stresses two threads: product differentiation and expanding end markets driven by AI and telecom scale. Record backlogs and co-created deployments with hyperscalers are presented as tangible demand indicators for companies that combine systems, interconnect components and software capabilities.
Market movements cited alongside the analysis show VIAV down 3.24% and CIEN down 4.00% in the snapshot provided in the note.
Conclusion
Stifel’s assessment singles out Ciena and Viavi as top picks within Applied Technologies - Equipment/Test based on addressable-market metrics, differentiated product lines and visible demand signals. The note highlights questions about how valuation will respond to longer-term market durability and flags potential upside not yet captured by models in the case of testing-related opportunities tied to advanced packaging and fiber initiatives.
