智通财经APP获悉，东吴证券发布研报称，重点关注2026年 M9产业链、光互联产业链投资机遇。PCB 材料向M9等级升级、光电共封装及"光入柜内"的确定性技术趋势。因此该行建议2026年重点关注 PCB M9 材料产业链投资机遇，以及CPO、光入柜内所对应的光芯片、光器件等领域的投资机遇。 东吴证券主要观点如下： SerDes 代际跃迁，驱动算力互联介质升级 算力芯片的互联带宽已成为衡量其性能的核心指标，而 SerDes(高速串行解串器)作为高速 IO 端口的核 心技术组件，其速率迭代直接决定了芯片互联带宽的上限。以英伟达为例，NVLink SerDes 已从 Ampere 架构的 56Gbps 演进至 Blackwell 架构的 224Gbps，支撑单芯片互联带宽实现代际跨越。然而， SerDes 速率的持续提升对 AI 服务器，交换机的信号传输介质提出严苛挑战。从速率瓶颈看，224G 以 上信号高频衰减剧增，驱动 PCB 覆铜板向 M9 级别升级;从功耗瓶颈看，SerDes 功耗占比随速率攀升， 光互联亟需通过光电近封装、共封装技术缩短与交换芯片的物理距离，以替代传统可插拔方案，实现能 效跃升。 Rubi ...

Ac t i o n | 23 Feb 2026 20:46:05 ET │ 31 pages China Communication Infrastructure CPO scale-up a new TAM, on top of upbeat 2027 pluggable demand CITI'S TAKE We evaluate the potential TAM for CPO optics supply chain in this report given the deployment in scale-up likely to come in late 2027. The optics supply chain will likely see stocking demand in 2H27. We assume 300/5k/209k units of CPO switches in 2025/26/27E (vs. prior 100k in 2027E) in which 169k units of CPO switch shipments are assumed for scale- up ...

Core Viewpoint - The optical fiber and cable market is experiencing a significant price surge driven primarily by the demand from AI data centers, rather than traditional drivers like FTTH or 5G construction [1][2]. Group 1: Market Dynamics - Since the end of 2025, the price of G.652.D bare fiber has been continuously rising, surpassing 30 yuan per core kilometer by February 2026, with actual transaction prices concentrated between 40 to 50 yuan per core kilometer, reflecting an increase of 94% to 144% [1]. - The demand structure for optical fibers has fundamentally changed due to the high consumption levels and specifications required by AI data centers, which exceed those of traditional telecom networks [1]. - The demand for special fibers like G.657.A2 and hollow-core fibers has surged to meet the low-latency and high-bandwidth interconnection needs of GPU clusters [1]. Group 2: Supply Constraints - The core raw material for optical fibers, optical preform, accounts for about 70% of the fiber's cost and has a long production cycle of 1.5 to 2 years, leading to tight supply constraints [2]. - Following previous years of price wars and supply clearances, there has been little large-scale expansion in production capacity, causing a mismatch between rising demand and constrained supply [2]. - As high-end special fiber demand surges, preform manufacturers prioritize capacity for higher-margin products, further squeezing the production of standard fibers like G.652.D [2]. Group 3: Investment Opportunities - Companies with optical preform production capacity, such as Yangtze Optical Fibre and Cable, Hengtong Optic-electric, Zhongtian Technology, FiberHome, and Hangzhou Hikvision, are expected to benefit significantly from the price increase [3]. - Key suppliers in the upstream of the computing power supply chain, particularly in the optical module sector like Zhongji Xuchuang and NewEase, as well as optical device manufacturers like Tianfu Communication and Shijia Photon, are also highlighted as potential investment targets [3]. - Companies with advanced technological reserves, particularly those involved in next-generation technologies like hollow-core fibers, are likely to see valuation catalysts as these technologies enter operator trials [3].
