An optical switch is a device that selectively routes optical signals from one fiber to another without converting them into electrical signals. These devices play a critical role in modern optical networks by enabling dynamic reconfiguration, wavelength routing, and protection. This paper compares the core differences between optical switches and electrical switches, clarifying their distinctions across seven key dimensions including signal conversion mechanisms, switching layers, latency, power consumption, and more. It also provides technical selection recommendations. Optical ports on switches typically require the insertion of optical modules for data transmission over fiber optics. Fiber optic connectors connect optical fibers and can be connected and disconnected faster than splicing.
