Lumentum is leveraging OCS and CPO to tap AI-driven demand as data centers shift from copper to optical.
LITE's OCS backlog exceeds $400M, with faster-than-expected ramp and CPO demand extending into 2027.
The Zacks Consensus Estimate pegs LITE's fiscal 2026 revenues at $2.91B, up 76.99% year over year.
Lumentum (LITE - Free Report) is aligning itself with two of the most important shifts in data center architecture, optical circuit switches (OCS) and co-packaged optics (CPO), both of which are gaining traction as AI workloads reshape network requirements. As hyperscale data centers expand rapidly, copper-based interconnects are hitting limits on bandwidth efficiency and power consumption, accelerating the transition toward optical architectures that can scale with next-generation AI clusters. LITE's early positioning across both platforms places it well to capture a disproportionate share of that shift.
The scale of this transition is reflected in the underlying market opportunity. Per Mordor Intelligence, the global optical switches market, within which OCS is a key application, stands at $8.06 billion in 2026 and is forecast to reach $12.71 billion by 2031 at a 9.54% CAGR, driven largely by hyperscale data center expansion. The CPO market is expanding faster, with Precedence Research estimating growth from $95 million in 2025 to more than $1 billion by 2034, implying a CAGR of 30.66%. LITE's relevance extends beyond market exposure, with active design-in positions across both segments at multiple hyperscalers.
Lumentum's execution reflects this demand. OCS backlog has surpassed $400 million, underpinned by multiple hyperscaler customers, and the first $10 million OCS quarter arriving three months ahead of schedule suggests the ramp is tracking faster than the original roadmap anticipated. In CPO, committed procurement extending into calendar 2027 signals that customer engagement has moved well past evaluation.
This demand environment is translating into growth. Lumentum reported fiscal second-quarter revenues of $665.5 million, up 65.5% year over year. The Zacks Consensus Estimate for LITE’s fiscal 2026 revenues is pegged at $2.91 billion, indicating 76.99% year-over-year growth. With both OCS and CPO still in their early stages, the broader demand they reflect appears to be heading increasingly in LITE's favor.
LITE Enjoys a Competitive Edge
Lumentum holds a structurally stronger position in the optical networking space than peers Marvell Technology (MRVL - Free Report) and Coherent Corp (COHR - Free Report) . In OCS, Lumentum operates as a dedicated platform provider, whereas Coherent's broader photonics portfolio dilutes its focus, and Marvell approaches the space primarily through silicon and DSP rather than optical switching. In CPO, LITE's laser expertise gives it a more foundational role in the architecture compared to Coherent, which spans a wider but shallower product mix, and Marvell, whose CPO ambitions remain tethered to its semiconductor rather than photonics capabilities. As both OCS and CPO move toward mainstream adoption, LITE's focused positioning gives it a more defensible standing than either Coherent or Marvell.
From a valuation standpoint, Lumentum stock is currently trading at a forward 12-month Price/Sales ratio of 11.77X compared with the industry’s 6.37X. LITE has a Value Score of F.
