Core Viewpoint - The article emphasizes that as AI computing power transitions from being limited by chips to being constrained by interconnectivity, optical modules are becoming the core infrastructure in the next phase of the computing power war [1][4]. Group 1: Transition in AI Infrastructure - The past two years have seen a focus on GPU performance, with Nvidia's stock serving as a barometer for AI investment sentiment [1]. - As the scale of AI clusters expands exponentially, the demand for transmission bandwidth has become increasingly critical [1][2]. - The optical communication industry is at a historical turning point, evolving from a mere accessory in communication networks to a vital component determining AI cluster efficiency [2][4]. Group 2: Bottlenecks and Technological Divergence - The traditional architecture based on electrical interconnects faces multiple bottlenecks in power consumption, bandwidth, and latency [8]. - The industry is witnessing a divergence in two technological paths: Co-Packaged Optics (CPO) and pluggable optical modules, with both expected to coexist rather than one replacing the other [9]. - CPO offers advantages in power consumption but poses challenges in maintenance and supply chain flexibility, indicating a gradual upgrade phase rather than a revolutionary shift [9][10]. Group 3: Market Dynamics and Investment Opportunities - Lumentum's stock reaching historical highs reflects a supply-demand logic rather than mere market sentiment, indicating a structural shortage in key optical communication components [12][14]. - By 2026, EML production capacity is expected to increase by over 50%, and demand for InP is projected to grow at a compound annual growth rate of 85% by 2030 [13][14]. - The current demand surge is driven by AI data centers rather than traditional telecom capital expenditures, providing a more stable and predictable growth trajectory [14][15]. Group 4: Reevaluation of Optical Modules - The perception of optical modules is shifting from being seen as mere accessories to being recognized as core assets in computing power [17][18]. - As data center communication volumes increase, the efficiency of optical interconnects becomes a critical variable in overall system performance [18]. - The competition among data centers will increasingly focus on the combined efficiency of computing, networking, and scheduling, positioning optical modules at the center of this ecosystem [18][22]. Group 5: Future Outlook - The article concludes that the next keyword in AI investment will be "efficiency," with a focus on connectivity rather than just computing power [20][21]. - The revaluation of the optical module industry is expected to unlock significant value, as the ability to efficiently connect and utilize computing power becomes paramount [22].
