Core Viewpoint - The article discusses the ongoing relevance of copper cables in the data center infrastructure, particularly in the context of AI and high-performance computing, despite the rise of optical technologies like CPO (Co-Packaged Optics) [1][29]. Industry Shift - Broadcom's CEO Hock Tan indicated that customers may continue using Direct Attach Copper (DAC) cables even as they transition to 400G SerDes by 2028, highlighting the cost and power consumption advantages of copper over fiber [3]. - NVIDIA's CEO Jensen Huang acknowledged the importance of both copper and fiber, suggesting that the widespread adoption of optical solutions may be delayed until 2028 [4]. - Analysts from Bank of America noted that while optical technologies dominate in scale-out scenarios, significant adoption in scale-up applications is not expected until 2026 or 2027, extending the lifespan of copper cables [4]. Copper Cable Differentiation - Copper cables are not a uniform technology but a continuously evolving group, with DAC being the most basic form, offering low power consumption and cost advantages [6]. - Active Electrical Cables (AEC) have emerged to extend the effective transmission distance of copper cables, with capabilities of up to 7 meters for 100G speeds, significantly improving their utility in data centers [7][8]. AEC Market Dynamics - Credo Technology dominates the AEC market with an estimated 88% share, offering various AEC products tailored for different data center scenarios [10]. - The AEC market is projected to grow significantly, with estimates suggesting it could reach $1 billion by 2028, driven by the increasing complexity of GPU servers [11]. TE Connectivity's Role - TE Connectivity is redefining copper cable technology through innovative connector designs and active backplane solutions, emphasizing the importance of copper as a foundational technology rather than a temporary solution [13][14]. Optical Technology Developments - The LPO (Linear Pluggable Optics) technology aims to reduce power consumption by eliminating DSP chips, achieving significant efficiency improvements [16]. - NPO (Near-Package Optics) serves as a transitional technology between traditional optics and CPO, offering operational flexibility [17]. Copper Cable Evolution - The ongoing advancements in semiconductor process nodes are driving the evolution of copper cables, with companies like Credo moving towards smaller nodes to reduce costs and power consumption [22]. - Broadcom's Co-Packaged Copper solutions are designed to integrate closely with chip packaging, enhancing performance while maintaining cost advantages [22]. Scale-Up vs. Scale-Out - The distinction between scale-up (vertical expansion) and scale-out (horizontal expansion) is crucial, with copper cables being particularly suited for scale-up scenarios where low latency and high bandwidth density are essential [24]. - Marvell's perspective aligns with the idea that CPO will have limited deployment in scale-up scenarios, reinforcing the coexistence of copper and optical technologies [25]. New Industry Landscape - The shift towards AEC has redefined the value chain in the copper cable industry, with Retimer chip manufacturers becoming central to competitive dynamics [27]. - Major data center operators are now prioritizing reliability and signal integrity in their copper cable selections, indicating a shift from passive to intelligent network infrastructure [28].

Group 1 - The company provides high-speed copper cables (DAC, ACC, AEC) to major connector manufacturers like Amphenol, which are used in Google's data center AI server clusters for short-distance, high-speed data transmission [2] - The company's high-speed cable business is positioned upstream in the supply chain, with direct clients including international companies such as Amphenol, Huber+Suhner, Molex, and TE Connectivity, as well as domestic connector firms like Luxshare, Qinghong, and Huafeng [2] - These direct clients further process the cables before supplying them to major server manufacturers, including Google, for end-use [2]
