The booming US stock market optical communication sector welcomes the earnings season. Needham recommends seven stocks before the performance report.

The parameters of AI large models are still expanding at a rate of approximately 100 times every two years, and the limit of computing power is no longer solely determined by the number of GPUs, but also by the "blood vessels" connecting these GPUs - the bandwidth and density of optical networks. As the first quarter earnings season of 2026 approaches, the market spotlight is shifting from AI computing power leaders like NVIDIA Corporation to the optical network companies that are laying down the "information superhighways" for AI data centers. A forward-looking report released by investment firm Needham on Tuesday provides key insights for the upcoming performance review. The next stop for AI: Computing power expansion triggers an "optical network super cycle" While AI chips remain the focus of the market, an undeniable industry trend is that as AI cluster sizes move from tens of thousands of GPUs to hundreds of thousands or even millions, traditional copper cables and InfiniBand networks are reaching physical limits. Needham analysts clearly point out in the report that Arista Networks is most likely to deliver better-than-expected results in the first quarter earnings, with significant growth coming from the AI backend network business. This assessment aligns with the explosive growth of the global optical communication market. According to the latest research from TrendForce, the global market for AI-specific optical transceivers is expected to jump from $16.5 billion in 2025 to $26 billion in 2026, with an annual growth rate exceeding 57%. The strong demand for 800G optical modules in North America's super-large data centers, coupled with the accelerated mass production of 1.6T products, is building an unprecedented "optical module super cycle." Therefore, Needham is bullish on the entire race track. Among the optical network companies set to announce their first quarter earnings, the report covers seven stocks, all of which received a "buy" rating, with five of them receiving significant target price increases. Deep dive into the seven core targets In this forward-looking report, Needham categorizes the seven companies into different tiers, highlighting the investment logic and market expectations. Arista Networks (ANET.US): The "new infrastructure hegemon" of AI networks Core logic: If NVIDIA Corporation is the "brain" of AI, then Arista is the "nervous system" connecting these brains. As the absolute leader in high-speed Ethernet switches, Arista is undergoing a strategic transformation from a traditional cloud data center supplier to an AI backend network architect. Just this month, the company officially doubled its 2026 AI network revenue target to $3.25 billion, confirming that open Ethernet solutions are accelerating the replacement of expensive InfiniBand solutions. Earnings highlights: Needham points out that sentiment towards ANET is "relatively weak," but this creates expectations for a positive surprise. Analyst Koontz expects Q1 revenue to grow by over 33-34% year-on-year, and the full-year revenue growth rate for 2026 is likely to be raised from the current guidance of 30% to 40%. Lumentum (LITE.US) and Coherent (COHR.US): Leaders in the photonics era Needham considers Lumentum to be one of the "best long-term positions," but warns of significant short-term price volatility. The company's moat lies in the laser chips required for co-packaged optics (CPO) and near-packaged optics (NPO). Wall Street predicts that its CPO/NPO business revenue will soar from $124 million in the 2026 fiscal year to $1.7 billion in the 2028 fiscal year, forming the bottom-line logic to support its target price of over $800. NVIDIA Corporation's $2 billion strategic investment in LITE, which has been seen by institutions as an endorsement of the transition from the "electronic era" to the "photonics era" for AI infrastructure. As Lumentum's strongest competitor, Coherent also dominates in the field of indium phosphide (InP) lasers and optical modules. Its data center and communication business revenue surged by 33.5% year-on-year in the last earnings report, and benefiting from a strategic partnership with NVIDIA Corporation, the stock price has risen by over 300% in the past year. Needham has raised its target price from $330 to $380, demonstrating continued recognition of its industry-leading position. Applied Optoelectronics (AAOI.US) and Fabrinet (FN.US): Elastic targets for capacity release AAOI's highlight lies in its astounding capacity expansion elasticity. To meet the demand for 800G and future 1.6T from customers such as Amazon.com, Inc., and Oracle, AAOI plans to significantly increase its monthly capacity for 800G/1.6T to over 500,000 units by the end of 2026, achieving a growth of 400%. Needham believes that AAOI is a direct beneficiary of the surge in demand for optical transceivers driven by AI/cloud capital expenditure, and has raised its target price from $130 to $190. Currently, AAOI has set a revenue target of over $1 billion for 2026, with Q1 revenue guidance of $150-165 million. As a provider of precision manufacturing services for optical communications, Fabrinet is deeply tied to industry giants such as Lumentum. In the last earnings report, its optical communication revenue grew by 36% year-on-year, with high-performance computing (HPC) business growing by a whopping 473% month-on-month. Needham's target price of $800 (originally $610) reflects a premium for the certainty of its capacity ramp-up. Ciena (CIEN.US) and Viavi Solutions (VIAV.US): The "shovel sellers" of the data deluge Ciena focuses on coherent optical transmission equipment for wide area networks and data center interconnections (DCI). Needham also considers it as one of the "best long-term positions," but notes that market expectations in the short term have led to price volatility. With the explosion of interconnection demand between AI data centers, Ciena's backlog has reached $7 billion, with revenue visibility extending to 2027. Analysts expect its 2026 fiscal year profit to grow by 132.4%. Viavi Solutions, as a "shovel seller" in the field of network testing and measurement, is expected to see a surge in demand for testing equipment due to the large-scale deployment of optical modules in AI data centers. While VIAV's business scale is relatively small, its stock price has shown significant elasticity, with a growth of over 260% in the past year. Needham has raised its target price from $36 to $53.
