如何看待当下的光模块行情？

Investment Rating - The report maintains a "Buy" rating for key companies in the optical module industry, including Zhongji Xuchuang and Xinyi Sheng [5][11]. Core Insights - The optical module market is experiencing rapid growth driven by the increasing demand for AI computing power, with price changes reflecting a healthy industry development rather than simple supply-demand dynamics [1][23]. - Optical modules are classified as technology-driven products rather than standard commodities, with their pricing following a unique industry pattern of "new product high gross margin → smooth decline after scaling → technological iteration" [2][24]. - Price reductions in optical modules do not necessarily lead to decreased profitability for companies; instead, leading firms can maintain or even enhance their profit levels through scale effects, process improvements, and supply chain optimization [3][25]. - The competition in the optical module industry has shifted focus from individual product pricing to continuous innovation and comprehensive solution offerings, which form the core competitive advantage of companies [4][27]. Summary by Sections Investment Strategy - The report recommends focusing on the optical communication sector, highlighting key players such as Zhongji Xuchuang, Xinyi Sheng, and Tianfu Communication, among others [9][14]. - It emphasizes the importance of technological iteration and product upgrades as the main growth drivers in the optical module industry [30]. Market Review - The communication sector has seen a decline, with operators performing relatively better compared to other segments [18][19]. - The report notes that the optical communication index has decreased by 6.7%, indicating challenges within the sector [22]. Optical Module Market Dynamics - The report outlines that the iteration cycle for 800G and 1.6T optical communication has shortened from 3-4 years to 1-2 years, with significant shipments expected for 800G and gradual ramp-up for 1.6T [2][24]. - The unique pricing model of optical modules is characterized by a predictable decline in prices as technology matures and production scales up [2][24]. Profitability and Competitive Barriers - Leading optical module companies have shown an ability to increase gross and net profit margins despite price reductions, supported by cost control and technological advancements [3][25]. - The report highlights that the core competitive barriers in the optical module industry are built around product upgrades and comprehensive capabilities rather than just pricing [4][27]. Recommendations - The report continues to favor the computing power sector and recommends investing in leading optical module companies while also suggesting attention to emerging players in the domestic computing power supply chain [8][29].
