这个文章来看下美银的一份深度研究报告，关于 AI 数据中心里的光学互连技术。到 2030 年，AI 光 学网络市场能达到 730 亿美元，占整个 AI 网络市场的近 40%。（文章中的观点都是美银的） 一、为什么光学技术突然这么重要了？ 先说个基本事实：数据中心里的设备之间要传输数据，传统上有两个选择——铜缆或者光纤。 铜缆的好处大家都知道：便宜、可靠、功耗低。所以业内一直有个说法叫"能用铜就用铜，必须用光 才用光"(copper if you can, optics if you must)。 但 AI 改变了游戏规则。 现在的 AI 训练集群，动不动就要把几万甚至十几万个加速器连在一起。这带来了三个铜缆解决不了 的问题： 第一是距离 。传统的直连铜缆（DAC）在高速率下只能传 2 米左右，连机架内的设备都不够用，更 别说跨机架了。虽然有源铜缆（ACC）能延长一些距离，但也就到此为止了。 第二是带宽 。AI 网络的带宽需求每两年翻一番。现在 800G 已经在大规模部署，1.6T 马上就要来 了，3.2T 也在路上。铜缆在这种速率下信号衰减太严重，根本扛不住。 第三是功耗 。这个可能是最致命的。Nvidia ...

Getty Images GSLC At A Glance Goldman Sachs ActiveBeta U.S. Large Cap Equity ETF (GSLC) is a passively managed exchange-traded fund (also known as an ETF) with an NAV of ~$14.7Bn that invests in large-cap American-listed stocks.

After further review of the fund, it's clear that there's a reason this large-cap equity ...
