《Every Stock Nvidia Needs to Keep the Ai Boom Going》
$CIEN未站边
Ciena 受 AI 驱动增长强劲，但因估值倍数偏高、且高度依赖少数客户，加之行业历来波动较大，风险不容忽视。
第四，网络。Sienna，股票代码 CN。AI 并不是在一台计算机上训练的，它要用成千上万台计算机，通过玻璃光纤电缆即时互相通信。Sienna 制造的就是以光速传输所有这些数据的设备。
AI 规模越大，这类网络的需求就越多。风险在于：这跟 Global Crossing 完全属于同一个行业，那个行业以巨大的繁荣和巨大的崩盘而闻名，而且它严重依赖仅仅少数几个超大客户。
Fourth, the network. Sienna, ticker CN. AI isn't trained on one computer. It uses thousands of them talking to each other instantly over glass fiber cables. Sienna makes the gear that carries all that data at the speed of light.
Bigger AI means a lot more of this networking. The risk. This is exactly the same industry as global crossing, famous for giant booms and giant buss, and it relies heavily on just a couple of massive customers.
