2026年5月：AI基建卡脖子，光缆HBM更要命
from AI观测站-AI Observatory
AI基础设施的瓶颈正从芯片转向光互联和高带宽内存（HBM），中国光通信厂商的产能已排至2027年初，而HBM需求则驱动SK海力士和三星利润暴涨，但也面临潜在的罢工风险。在此背景下，全球资本重新评估中国科技股，将A股的AI硬件板块视为新的投资避风港。AI数据中心光互联告急* 中国光缆制造商产能已排至2027年初，数据中心光纤需求占比将从2024年不足5%飙升至2027年的30%。* Meta和NVIDIA已与康宁签署多年供应协议，以锁定光纤和连接产品的长期供应。* 光互联短缺将直接拉长数据中心交付周期，即使GPU到货，集群也无法及时组网，降低算力利用率。* AI基础设施瓶颈从“芯片短缺”转向“光互联短缺”，光缆扩产周期长达18-24个月。HBM超级周期与供应链挑战* SK海力士Q1营业利润同比增长5倍，三星飙升超750%，均由HBM需求驱动。* AMD Ryzen AI MA...去小宇宙查看完整单集简介在小宇宙查看该单集文稿
