Optical switching is a technology that enables the routing of data using light instead of electrical signals. This method utilizes devices like optical switches to direct light beams through various paths, allowing for faster and more efficient data transmission. By leveraging the properties of light, optical switching can handle large amounts of data with minimal delay. This technology is crucial for modern communication networks, such as fiber optic networks, where high-speed data transfer is essential. Optical switching helps improve bandwidth and reduces energy consumption, making it a key component in the development of advanced telecommunications systems.
