🔑 增強重點摘要

•The transition to optical interconnects is driven by the 'copper bottleneck' in AI clusters, where traditional electrical signaling fails to maintain signal integrity at the 800G and 1.6T speeds required by next-generation GPUs.
•Corning's proprietary 'SMF-28' ultra-low-loss fiber technology is being optimized specifically for Nvidia's NVLink Switch systems to minimize latency and power consumption across massive rack-scale deployments.
•Chinese optical manufacturers, including YOFC and Hengtong Optic-Electric, are aggressively pivoting from traditional telecom fiber to specialized 'AI-grade' multi-core and hollow-core fibers to circumvent potential US export restrictions on high-end optical components.

🛠️ 技術深入

Shift from traditional copper Direct Attach Cables (DAC) to Active Optical Cables (AOC) and pluggable optical transceivers.
Implementation of Co-Packaged Optics (CPO) to integrate optical engines directly onto the GPU/Switch substrate to reduce electrical trace length.
Utilization of high-density fiber ribbon cables to support the increased port density of Nvidia's Blackwell and post-Blackwell rack architectures.
Focus on reducing 'thermal overhead' by moving heat-generating electrical-to-optical conversion components away from the GPU die.

🔮 前景展望AI analysis grounded in cited sources

Nvidia will phase out copper DACs for intra-rack communication by 2028.

The physical limitations of copper signaling at 1.6T speeds make optical interconnects the only viable path for maintaining signal integrity in high-density AI clusters.

China will increase its share of the global AI-specialized optical component market.

Domestic Chinese firms are heavily investing in R&D for high-capacity optical infrastructure to reduce reliance on Western technology amid tightening trade restrictions.
