面向AI基础设施的光互连

活动介绍

随着AI基础设施的快速发展，支持大型语言模型（如ChatGPT）的需求不断增长，网络解决方案必须在容量和速度上同步扩展。传输速率和I/O带宽的提升加速了研发周期，数通行业目前聚焦于200Gbps每通道的开发，并已经开始探索能够满足400Gbps每通道应用需求的下一代技术。

在本次网络研讨会中，行业专家将深入探讨光信号波特率向100G和200G波特升级所面临的技术挑战，特别是使用强度调制与直接检测（IM-DD）的光互连技术。尽管直调直检仍然是数据中心网络中性价比最高的方案，但在这些高速率下保持和过去一样的光纤链路距离的难度大幅增加。需要从所有可能的技术维度进行创新和研究来使能下一代光互连解决方案，本次研讨则将视线投向传递光信号的媒介：光纤链路和信道。

我们特别邀请世界顶尖光缆厂商CommScope的数据中心架构总监，分享支持下一代光互连的光纤技术进展和标准化趋势，解析新的光纤标准如何帮助行业在实现200Gbps/通道（适用于多模光纤MMF和单模光纤SMF）以及400Gbps（适用于SMF）时，确保光互连的链路稳定性和频谱效率的不断演进。

欢迎加入我们，共同了解面向AI基础设施的光互连技术发展趋势及光纤的创新。

The Future of Optical Interconnects for AI Infrastructure

As AI infrastructure expands rapidly to support the development of large language models like ChatGPT, networking solutions must scale in both capacity and speed. The rise in lane rates and I/O bandwidth is driving faster R&D cycles, with the industry now focusing on 200G/lane development and exploring 400G/lane for future needs.

In this webinar, industry experts will explore how the shift to 100G and 200G baud signaling rates poses new challenges for optical interconnect technologies, particularly using Intensity Modulation with Direct Detection (IM-DD). Although IM-DD remains the most cost-effective option for data center networking, maintaining and extending optical link reaches at these high rates is becoming increasingly difficult.

Our speakers will discuss key advancements in fiber technology and standardization that could support the next generation of optical interconnects. They will provide valuable insights into how new fiber specifications could help maintain the efficiency and performance of optical links as industry moves towards 200Gbps/lane with multimode fiber (MMF) and single-mode fiber (SMF), and 400Gbps with SMF.

Join us to understand the evolving landscape of optical interconnect and the fiber innovations that will power the AI-driven future.
