Core Viewpoint - The article discusses the current state and future potential of Co-Packaged Optics (CPO) technology in the AI infrastructure landscape, emphasizing that while CPO is seen as a next-generation technology, its widespread adoption is not imminent due to existing technological limitations and market dynamics [1][24]. Group 1: Current Industry Sentiment on CPO - Broadcom's CEO Hock Tan stated that silicon photonics will not play a significant role in data centers in the short term, indicating that CPO is not a leapfrog technology but rather a last resort when existing technologies reach their limits [1][24]. - Major industry players, including Arista, Credo, Marvell, and Lumentum, echoed similar sentiments at the Barclays Global Technology Conference, suggesting a cautious approach towards CPO adoption [1][24]. Group 2: Shift in Industry Focus - The AI industry has shifted its focus from merely increasing computing power to addressing interconnectivity and system-level architecture, as the bottleneck has moved from computational capacity to interconnect capabilities [3][4]. - Companies are now prioritizing terms like Scale-Out, Scale-Up, and Scale-Across, indicating a deeper understanding of the infrastructure bottlenecks in AI [4]. Group 3: Horizontal and Vertical Scaling - Horizontal scaling (Scale-Out) is currently dominated by pluggable optics, with CPO technology not yet widely adopted due to the existing 800G and 1.6T technologies still being the main focus [7][8]. - Vertical scaling (Scale-Up) was initially seen as a promising application for CPO, but its timeline has been pushed back, with large-scale deployment expected around 2027-2028 [9][10]. Group 4: Challenges Facing CPO - CPO faces significant challenges, including higher costs, reliability issues, and power consumption concerns, which have delayed its mass production [18][24]. - The complexity of system design and the need for a mature supply chain are also major obstacles to the widespread adoption of CPO technology [19][24]. Group 5: Alternative Solutions - Transition solutions like LPO, AEC, and ALC are increasingly being recognized as viable alternatives to CPO, with many companies focusing on these technologies to meet current demands [15][25]. - LPO technology has already seen large-scale deployment, providing cost and power advantages, while AEC and ALC are being developed to offer reliability similar to copper cables with the bandwidth of optical solutions [15][25]. Group 6: Future Outlook - Industry predictions suggest that CPO will begin to see deployment in specific high-density systems around 2028, but the current focus remains on optimizing existing technologies [26][27]. - The industry consensus is that CPO will not be the immediate solution until existing technologies reach their limits in terms of power, density, and reliability [27].
