OCS all-optical switching products are characterized by their speed, scalability, and efficiency in handling massive volumes of data. This 4Q25 report is a continuation of and update to Cignal AI's previous OCS reports. Since the report's last publication in January 2025, and the webinar Optical Circuit Switching for AI Scaling and Datacenter Automation in July 2025, the OCS forecast has been updated based on newer information. Optical Circuit Switches (OCS) by Application (Telecommunications, Data Communications), by Types (Robotic Switching, 3D-MEMS, Beam Steering), by Technology (MEMS-based Switches Liquid Crystal Switches Electro-Optic Switches Piezoelectric & Silicon Photonics Switches Others, Liquid Crystal. The exponential growth of data traffic, primarily fueled by the proliferation of Artificial Intelligence (AI) and high-performance computing (HPC), is pushing traditional electronic packet-switched networks to their physical limits. By Type: MEMS-based switches are projected to. Hopeful vendors are jockeying for position as hyperscalers evaluate new data center switching options that could drastically reduce power needs and smash a critical bandwidth bottleneck. The technology they're placing their bets on? Optical Circuit Switching (OCS).
