Core Viewpoint - The article discusses the emerging market for Optical Circuit Switching (OCS) technology, highlighting its advantages over traditional electronic switches and the potential for significant market growth, particularly in data centers and AI clusters [2][4][30]. Summary by Sections OCS Technology Overview - OCS enables direct switching of optical signals between fiber ports without the need for optical-electrical-optical conversion, resulting in lower latency, reduced power consumption, and improved compatibility [2][10]. - The technology faces limitations such as longer switching times and lower channel flexibility, making it less suitable for high-concurrency communication loads [10][11]. Industry Adoption and Market Potential - Google has been a pioneer in adopting OCS technology, integrating it into its Jupiter data center network and AI clusters, which has led to significant improvements in network efficiency and cost reduction [3][19][22]. - Cignal AI projects that the OCS market could exceed $1.6 billion by 2029, with Coherent identifying a $2 billion potential market opportunity for OCS switches [4][30]. Key Players and Technological Developments - Major companies involved in OCS technology include Google, Lumentum, and Coherent, with various technological approaches such as MEMS, digital liquid crystal, and piezoelectric systems being explored [11][13][15]. - The OCS industry is moving towards open standards and collaboration, as evidenced by the establishment of the OCS sub-project under the Open Compute Project (OCP) [29]. Initial Revenue and Future Growth - Companies like Lumentum and Coherent have reported initial revenues from OCS, with expectations for continued growth as demand increases from large-scale cloud providers [30][31]. - The article emphasizes the importance of monitoring the OCS industry's trends and the potential for significant contributions to the supply chain as OCS technology becomes more widely adopted in data centers [32].
