579. 射频光纤：AI数据中心连接的新纪元
from 知为谁 · host 知为谁
本文概述了数据中心连接技术的正处于从传统铜缆向无线电射频方案转型的关键阶段。随着人工智能对算力的需求激增，传统铜线在处理高带宽数据时面临严重的物理极限与功耗难题。初创公司如 Point2 和 AttoTude 正在研发利用毫米波与太赫兹频率的新型传输技术，力求在降低能耗的同时提供超越铜缆的传输距离。这种射频光纤替代方案不仅比光学器件成本更低、更易于制造，还能通过更细的线缆简化数据中心的散热管理。未来，这些技术有望直接集成到 GPU 芯片封装中，彻底革新大型 AI 模型的训练效率。内容来源：https://spectrum.ieee.org/rf-over-fiber
