In this update to our OCS report we cover more vendors and technologies, investigate additional applications, and update our market forecast. This 4Q25 report is a continuation of and update to Cignal AI's previous OCS reports. 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. Optical Circuit Switches (OCS) by Application (Telecommunications, Data Communications), by Types (Robotic Switching, 3D-MEMS, Beam Steering), by North America (United States, Canada, Mexico), by South America (Brazil, Argentina, Rest of South America), by Europe (United Kingdom, Germany, France. The Open Compute Project Foundation (OCP), the nonprofit organization bringing hyperscale innovations to all, today announced the formation of a new Optical Circuit Switching (OCS) Subproject. The exponential growth of artificial intelligence (AI) and machine learning (ML) workloads is pushing the limits of traditional data center networks.

The optical ports on the switch are usually paired together, with one TX sender and one RX receiver. Optical switches are used to reconfigure wavelength cross-connects, enabling support for new light paths. A passive optical network (PON) or Gigabit Passive Optical Network (GPON) is a point-to-multipoint (P2MP) network that uses a combination of active transmission equipments and passive cable components to provide network connectivity to end user's devices.

Co-Packaged Optics (CPO) is an optoelectronic co-packaging technology that integrates an optical module (responsible for optical signal transmission and reception) and a switch ASIC (responsible for electrical signal processing) into the same physical package. NVIDIA's co-packaged optics (CPO) switches with integrated silicon photonics are the world's most advanced networking solution for the era of agentic AI. From Jensen Huang showcasing CPO switches at GTC 2025 to a wide range of vendors demonstrating optical engines integrated inside ASIC. This article provides a comprehensive overview of CPO optical modules, exploring their technology, benefits, challenges, and the pivotal role they play in future data centers.

When two ports need to communicate, the controller configures a path in the optical switch matrix, using optical components to route the optical signal from one fiber to another, forming an. These devices play a critical role in modern optical networks by enabling dynamic reconfiguration, wavelength routing, and protection switching. Optical switching is the process of controlling the destination of individual optical information signals. Initially, digital systems used Time Division Multiplexing (TDM), which broke different voice or data signals into pieces and sent them in alternating slots in one stream.
