隨著人工智慧基礎設施不斷擴充套件，以支援大語言模型（LLM）的訓練與推理，對更高速、更具可擴充套件性的光互連解決方案的需求正持續加速。在我們首場網路研討會中，業界專家共同探討了如何更新光纖鏈路標準，以支援100G和200G波特率光訊號傳輸，對應200G/通道和400G/通道的PAM4調製技術——這是建設下一代光互連網路的重要第一步。本次第二場研討會將聚焦於支援400G/通道 PAM4 光訊號傳輸所需的關鍵器件技術，尤其是高速調製器和光探測器的設計挑戰。
我們榮幸邀請到華為伊普斯維奇研究中心 主任工程師陳欣博士擔任本期嘉賓講者。他近期在OFC 2025大會上發表了一篇後期投稿論文，展示了高速整合EML器件的突破性成果。在此次分享中，陳博士將深入解析高速乙太網互連中關鍵III-V族器件（如電吸收調製雷射器EML、光電探測器PD、基於InP的馬赫-曾德爾調製器MZM）的應用與發展趨勢，探討如何透過這些技術創新，推進400G/通道 PAM4 光鏈路的落地，支撐AI和資料中心互連（DCI）網路的發展。

The Future of Optical Interconnects for AI Infrastructure: Powering the Next Leap to 400G/lane
As AI infrastructure continues to scale in support of training and inference for large language models (LLMs), the demand for faster, more scalable optical interconnect solutions is intensifying. Our first webinar highlighted the industry's push to update fiber link standards—an essential first step in building the next generation of optical interconnects. These updates are necessary to accommodate 100G and 200G Baud PAM4 signaling.
In this second session, we shift the focus from the transmission medium to the key enabling technologies for high-speed signal generation and detection. Specifically, we’ll explore the electro-optic components that make 400G/lane PAM4 signaling feasible and efficient, which is the next major leap in optical interconnect speed.
We are honored to welcome Dr. Xin Chen, Principal Engineer at Huawei UK, as our guest speaker. Dr. Chen recently presented a post-deadline paper at OFC 2025 on record-breaking high-speed electro-absorption modulated lasers (EMLs). In this session, he will share insights into the application and evolution of critical III-V components—such as EMLs, photodiodes (PDs), and InP-based Mach-Zehnder modulators (MZMs)—within high-speed Ethernet interconnects.
Dr. Chen’s presentation will provide a deep dive into the technical advancements and integration strategies needed to support 400G/lane PAM4 optical links, highlighting how these innovations are paving the way for next-generation networks supporting data center interconnect (DCI) and AI workloads.
Speakers:
Guangcan Mi, Principal Engineer, Huawei
Dr. Xin Chen, Principal Engineer, Ipswich Research Center, Huawei Technologies Research & Development Ltd., UK
This session is the second in our ongoing webinar series addressing the industry’s evolving optical networking needs, offering a platform for expert insights and discussions on the technologies that will shape the AI-driven future.
