全球云厂商和 AI 实验室持续扩建数据中心后,跨洲数据传输需求也在上升。当前主干网络仍主要依赖海底光缆,但这类设施建设和维修成本高,受损后的恢复也较慢。美国初创公司 EON 正试图用太空激光链路切入这一市场。

完成 1075 万美元种子轮

EON 今年 5 月成立,现已结束隐身状态。公司宣布完成 1075 万美元种子轮融资,投资方包括 General Catalyst 和 Andreessen Horowitz。EON 由 Charlie Horowitz 和 Tyler Presser 创立,计划部署搭载激光通信设备的卫星,在轨道上连接不同大洲的数据中心。

据 TechCrunch 报道,EON 目前接触的客户包括超大规模云厂商、AI 实验室以及内容分发网络运营方。公司希望先覆盖现有基础设施不足、或传输成本偏高的跨洲线路,例如法国至澳大利亚,以及非洲与南美之间的连接。

先建约 20 颗卫星网络

EON 计划先部署约 20 颗卫星。按照公司设想,每颗卫星可在两大洲之间提供一条专用链路,首批卫星将为早期客户提供 24 小时覆盖。地面部分则会在不同区域设置站点,服务附近的数据中心和 CDN 节点,并通过冗余站点和天气数据提升稳定性。

报道提到,海底光缆的传输速度通常可达每秒 200 太比特以上,而 EON 给出的初始目标是每秒 2.4 太比特。相比之下,此前一些商业地空激光通信演示项目的吞吐量约为 2.5 Gbps,EON 的目标明显更高。

首颗演示星瞄准 2027 年底

这一路线的难点在于,激光信号穿过大气层时容易发生畸变,云层也会影响传输。EON 表示,将把研发重点放在自研光通信终端和高精度指向部件上,卫星平台则倾向采购现成产品,以缩短开发周期。

公司称,本轮融资将主要用于建设光学实验室、扩充工程团队,并在发射前完成地面测试。按其时间表,首颗演示卫星希望在 2027 年底前后发射,光学下行传输能力至少达到 800 Gbps,最高可能接近 1 Tbps。

AI 数据中心成主要需求方

投资方 General Catalyst 认为,这家公司同时切中 AI 和基础设施韧性两条主线。随着 AI 训练、推理和全球数据同步需求增加,数据中心之间对高带宽专用链路的需求也在扩大。

不过,这一方向已有竞争者。蓝色起源此前公布过 TeraWave 计划,准备建设更大规模的卫星网络,面向大型客户提供最高 6 Tbps 的连接能力。行业研究人士 Caleb Henry 表示,数据中心客户对链路质量和冗余要求很高,卫星通信要真正满足这类场景,落地难度仍然不低。

U.S. inflation report to be the next test for the Fed's interest rate hikes; Market bets on another hike in December after 165,000 new jobs created in October
After the United States added 165,000 new jobs in October, the inflation report released on November 10 may become a key test of the Federal Reserve's interest rate expectations. In September, CPI rose year-on-year to 3.7%, and the market's probability of a 25-basis-point interest rate hike in December is now close to 80%.

Amazon's new basic model Kindle proves that you don't necessarily need fancy features
After Amazon updated its Kindle product line in October, the basic 6-inch Kindle model remains the cheapest entry-level option. The article argues that although it lacks features such as warm light, waterproofing, and automatic brightness, the new model is lighter, thinner, has a flatter screen, and has faster software, making it still worth considering.
