$太辰光(SZ300570)$ $新易盛(SZ300502)$ $东田微(SZ301183)$

如下信息均来自OFC、GTC大会后,海外上市公司投资者交流会、海外投行分析师公开材料的整理,未有个人观点。

1、光模块抢了交换机的C位

DCI/DCN投资,在400G的时代光模块已经达到70%,交换机不到30%。那么意味着800G时代85%?按照这个市场价值转移的逻辑,中际旭创(SZ300308)的市值,远远超过中兴通讯,就是历史的必然。思科投资者交流会高管吐槽 “And the result is that the optics is now becoming a much more signi fi cant portion of the cost. So at 100 gig, it represents about 50% of the cost and at 400 gig and 800 gig, it's well over half the cost approaching 70% of the total cost. And this in fl uences our thinking around optics investment because if we're going to remain relevant for customers who want to buy a whole solution from Cisco, this would include enterprise customers, public sector customers as well as service provider customers. We need to have a full portfolio that includes the optics and the ports.”

结论,光学现在成为成本中一个更加重要的部分。因此,在100G时,它约占成本的50%,而在400G和800G时,它远超过一半的成本,接近总成本的70%。这影响了我们对光学投资的思考,因为如果我们想对那些想要从思科购买完整解决方案的客户保持相关性,这将包括企业客户、公共部门客户以及服务提供商客户。我们需要拥有一个包括光学和端口的完整产品组合。

2、DCN光通信市场增速比想象中的还要大

Coherent(仅次于中际旭创的全球老二)预计TAM规模从50亿美金(2024)增长到160亿美金,,CAGR 30%。“Cloud data center opportunity forecast to track to $16 bn by 2028. The Cloud Data Center Photonics market is expected to expand at a ~30% CAGR from $4.5 bn in 2023 to $16 bn in 2028, including Intra-Data Center Transceivers (200G-1.6T) expanding from ~$3 bn to ~$9 bn, ZR/ZR+ Modules for DCI (400G-1.6T) expanding from $1.2 bn to $4.5 bn, and Advanced Switching & Transport for Cloud expanding from~$0.5 bn to ~$2 bn.”

复合年增长率30%。“预计到2028年,云数据中心的市场机会将达到160亿美元。云数据中心光学市场预计将以约30%的复合年增长率从2023年的45亿美元增长到2028年的160亿美元,其中包括数据中心内部收发器(200G-1.6T)从约30亿美元增长到约90亿美元,用于数据中心互联(DCI)的ZR/ZR+模块(400G-1.6T)从12亿美元增长到45亿美元,以及云计算的高级交换与传输从约5亿美元增长到约20亿美元。”

3、铜进光退被证伪

大摩分析师终于搞明白了,DGX GB200 NVL7这种大集群系统,“NVDA’s GTC event announced transition from 4 optical ports in a data center to 36 ports for 1.6T capacity, or 18x increase in opportunity for optical transceivers for a fully-loaded system;” 一层铜两层光,光模块的需求要扩大18倍。(造假太高,有没有土豪这样去建,是另外一回事。需要推动光模块降低成本)

NVDA的GTC活动宣布,数据中心的光学端口将从4个端口过渡到36个端口,以实现1.6T的容量,或者说是光学收发器在一个满载系统中的机会增加了18倍。
