An optical bridge is essentially a multi-port device that connects multiple optical fibers and manages the routing of data between inputs and outputs, similar to how a network switch directs packets between devices . Some optical bridges convert light signals into electrical signals for processing before converting them back to light, while all-optical bridges route light directly without electrical conversion, maintaining high-speed, low-latency transmission .
While an optical bridge performs the same basic role as a switch—connecting multiple network paths and directing traffic—it is specialized for fiber optic networks and can operate entirely in the optical domain. Therefore, it is accurate to describe an optical bridge as a type of switch, but with distinctions in layer of operation, signal handling, and technology compared to traditional electronic switches .
