光通信：2026 年 OFC 光纤通信展总结 -亮点纷呈，聚焦核心市场-Optical North America OFC 2026 Wrap-Up Bright Lights, Big City

Summary of Optical Industry Conference (OFC) 2026 Industry Overview - The conference highlighted a strong demand for optical solutions, with supply constraints being the primary challenge faced by vendors [4][9] - Ongoing debates regarding optical architectures, particularly around Co-Packaged Optics (CPO) and Optical Circuit Switching (OCS), with a consensus that optical content is increasing as bandwidth needs rise [4][9] Key Takeaways - Demand vs. Supply: Demand for optical solutions is significantly outpacing supply, particularly from hyperscalers who are collaborating closely with optical vendors [4][9] - Market Sentiment: Vendors expressed optimism about current market conditions, although there is a caution regarding future execution and potential volatility in stock valuations [4][12] - Investment Trends: Increased investment in optical technologies is driven by the growing bandwidth requirements across networks, with copper reaching its limits [5][9] Technological Developments - Co-Packaged Optics (CPO): - CPO remains a hot topic with debates on its adoption ranging from 5% to 30% over the next few years. NVDA is a key player in this space [10][11] - Challenges include a largely closed ecosystem and serviceability issues [10] - Optical Circuit Switching (OCS): - OCS is gaining traction, with potential for significant market opportunities. It is noted for its power-saving capabilities by eliminating the need to switch back to electrical layers [10][11] - Multi-Rail Technology: - This technology allows for significant densification of networks, with a total cost of ownership (TCO) 50-70% lower than current solutions [10] - eXtra-Dense Pluggable Optics (XPO): - Introduced by Arista, XPO offers four times the density of current solutions, addressing power challenges and appealing to hyperscalers [10] Company-Specific Insights - Ciena (CIEN): - Reported 76% year-over-year growth from data center customers and aims for 28% growth in FY26, contingent on supply availability [13] - Marvell (MRVL): - Positioned strongly in networking with a focus on optical circuit switching and coherent technologies, expecting significant growth in ASICs [14][15] - Cisco (CSCO): - Noted a 40% share of optical in cloud orders and sees opportunities in scale-across and DCI markets, though cautious about CPO adoption [17] - Lumentum (LITE): - Anticipates a growing total addressable market (TAM) for optical content, with expectations of a $1 billion+ business in OCS by 2027 [18] - Coherent (COHR): - Identified a $50 billion existing serviceable available market (SAM) with additional growth opportunities in OCS and thermal solutions [19] - Corning (GLW): - Highlighted innovations in fiber technology and expressed optimism about CPO revenue growth starting in 2027 [23] Market Dynamics - Vendor Diversity: - There is a strong desire for vendor diversity among hyperscalers, but achieving this is challenging due to the dominance of certain players like NVDA and LITE [11] - Valuation Trends: - Current valuations are seen as largely full, with expectations for stocks to trade towards bull cases in the near term, particularly as the AI complex continues to grow [12] Conclusion - The OFC 2026 conference underscored the robust demand for optical solutions amid supply constraints, with significant technological advancements and company-specific growth strategies shaping the future of the optical industry. The focus on open ecosystems and diverse vendor participation will be critical as the market evolves.
