Welcome to our GTC Paris at VivaTech 2025 wrap-up. Hello everyone, I'm Dion Harris, Senior Director of HPC and AI Infrastructure Solutions at NVIDIA. Europe was the birthplace of the first two industrial revolutions and where modern manufacturing emerged.Now, the fourth industrial revolution has arrived: the age of AI. This year, we showcased something remarkable—the acceleration of AI across every corner of Europe. In his keynote, Jensen Huang shared how we're entering the era where agentic AI can understa ...

Core Insights - GTCR, a Chicago-based private equity firm, achieved a significant exit by selling Worldpay for $24.25 billion, marking the largest private equity exit of 2025 so far [2][3] - The firm has managed to navigate a challenging market environment, completing notable transactions while many in the industry struggle to find buyers for their businesses [4][5] Group 1: Company Performance - GTCR manages $45 billion in assets, which is relatively small compared to major players like Blackstone and KKR, yet it has executed a remarkable transaction [3] - The firm sold Worldpay less than two years after acquiring a 55% stake from FIS for $18.5 billion, effectively doubling its investment [3] - GTCR is expected to return over $5 billion to investors this year, continuing a strong performance record for its flagship funds [4][5] Group 2: Historical Context and Leadership - Founded in 1980, GTCR has a long history in the private equity sector, with its founders being pioneers in the industry [5] - The current co-CEOs, Collin Roche and Dean Mihas, represent the second generation of leadership, with Roche having joined in 1996 and Mihas in 2001 [6] Group 3: Recent Transactions - Prior to the Worldpay sale, GTCR sold AssuredPartners for $13.45 billion and has also divested smaller companies like Antylia Scientific and Itel for over $1 billion each [4][5] - The Worldpay deal involved a complex asset swap with Global Payments, which acquired Worldpay while selling its card issuing solutions to FIS for $13.5 billion [7] Group 4: Future Strategy - GTCR is focusing on identifying new acquisition opportunities, having raised a new flagship fund of $11.5 billion and a strategic growth fund of $3.6 billion [8] - The firm currently has over $10 billion available for deployment, indicating a strong position to capitalize on market uncertainties [8]

如果您希望可以时常见面，欢迎标星收藏哦~ 2025 年 OFC 展会明确表明：数据中心向 CPO 交换机的转型不可避免，其主要驱动力在于 CPO 带来的功耗节省。 从黄仁勋在 2025 年 GTC 大会上展示 CPO 交换机，到众多厂商在 2025 年 OFC 展会上演示集成 在 ASIC 封装内的光引擎，共封装光学技术已无处不在。 值得注意的是，Arista 联合创始人、数据中心网络领域的长期远见者安迪・贝托尔斯海姆（Andy Bechtolsheim）尚未改变立场。在 2025 年 OFC 展会上，他继续主张线性可插拔光学（LPO）是 更优选择。LPO 移除了板载数字信号处理器，功耗较传统可插拔光学器件显著降低 —— 通常减少 30-50%。更多细节可查看我的帖子。 安迪的核心论点是，至少在 1600G 代际，LPO 与 CPO 的功率效率大致相当。那么，为何要接受 CPO 额外的复杂性呢？然而，在这些更高的 SerDes 速率下，LPO 面临着 ASIC 与面板光器件之 间电通道插入损耗的挑战。安迪认为，在 1600G 代际，可通过带近封装连接器的跨接电缆来缓解 这一问题。 他对 CPO 的担忧包括：失 ...

Core Viewpoint - The transition of data centers to Co-Packaged Optics (CPO) switches is inevitable, primarily driven by the power savings offered by CPO technology [1][2]. Group 1: CPO Technology and Market Trends - CPO technology is gaining traction as it significantly reduces power consumption, with potential savings of 30-50% compared to traditional optical devices [1][2]. - The industry has made substantial progress in CPO reliability over the past two years, making it a viable option for future high-speed data rates [2]. - The upcoming 400G SerDes generation may see CPO as the only feasible choice due to excessive insertion loss from traditional PCB traces and cables [2]. Group 2: Technical Integration of CPO - CPO solutions typically integrate electronic integrated circuits (EIC) and photonic integrated circuits (PIC) within the same package [3]. - Two main integration methods for optical engines within ASIC packages are the silicon interposer approach and the organic substrate approach [4][5]. - The silicon interposer method allows for high-density connections but complicates thermal management due to the proximity of high-power EICs [6]. - The organic substrate method offers better thermal isolation and modularity, allowing for independent testing of optical engines before assembly [7][8]. Group 3: Bandwidth Density and Performance - Bandwidth density, a critical metric for CPO solutions, measures the amount of data transmitted per millimeter along optical interfaces, typically expressed in Tbps/mm [9]. - Higher bandwidth density is essential to meet the explosive growth in bandwidth demand in data centers and high-performance computing systems [9]. Group 4: Competitive Landscape - Broadcom's Bailly CPO switch integrates eight 6.4 Tbps optical engines, achieving a total external bandwidth of 51.2 Tbps [12]. - NVIDIA's Quantum-X InfiniBand switch aims for higher scalability, targeting over 100 Tbps with advanced optical engine integration [17][18]. - Broadcom's next-generation switches are expected to reach 102.4 Tbps, while NVIDIA's architecture is designed for future demands of 200G SerDes and beyond [16][19]. Group 5: Power Efficiency and Thermal Management - Both Broadcom and NVIDIA report significant reductions in power consumption per bit with their CPO solutions, with Broadcom achieving approximately 5.5W per 800 Gb/s port compared to 15W for traditional modules [35]. - Effective cooling solutions, such as liquid cooling, are necessary to manage the heat generated by high-density ASIC packages [35][36]. Group 6: Future Directions and Challenges - The industry is exploring advanced coupling methods, such as vertical coupling and multi-core fibers, to enhance optical connectivity and bandwidth density [38][40]. - Challenges in deploying CPO include ecosystem disruption, operational complexity, and the need for robust reliability validation [42][43]. - CPO's prospects appear brighter in vertical scaling applications, where integrated solutions from single vendors can simplify procurement and deployment [45].
