Investment Rating - The report maintains a "Positive" investment rating for the communication equipment industry [7]. Core Insights - Optical Circuit Switching (OCS) technology allows for routing and forwarding of optical signals without optical-electrical conversion, offering ultra-high transmission speeds, low latency, low power consumption, and high stability compared to traditional switches. This technology is expected to significantly enhance the value of the industry chain in the long term [2][10]. - Google has integrated OCS technology into its TPU v4 generation, which is now in large-scale deployment. Major overseas optical communication leaders are actively promoting OCS products, with significant revenue contributions expected by 2026 [2][10]. Summary by Sections OCS Technology Overview - OCS operates on the principle of direct optical signal switching, eliminating the need for optical-electrical conversion, thus providing advantages such as ultra-high transmission speed and low power consumption. It is seen as a potential long-term replacement for electrical switches [10]. - LightCounting predicts that OCS shipments will experience explosive growth, reaching 10,000 units in 2023 and exceeding 50,000 units by 2029 [10]. Competitive Landscape - There are three main approaches to OCS technology: MEMS, Digital Liquid Crystal (DLC), and Direct Laser Beam Steering (DLBS). Google and Lumentum primarily use the MEMS approach, while Coherent employs the non-mechanical DLC method [10]. - The report highlights that Lumentum and Coherent have begun generating revenue from their OCS businesses, with expectations for continued revenue growth in upcoming quarters [4][10]. Market Outlook - The report suggests that OCS technology will replace electrical switches in the spine layer first, with potential penetration into the leaf/ToR layer in the future. The market for OCS is projected to expand significantly, with an estimated market space of around $2 billion [10]. - Key players to watch include optical system manufacturers with first-mover advantages, as well as manufacturers of passive optical components and laser sources [10].
