An all-optical Ethernet switch is a network switch whose service ports are entirely optical, meaning every interface uses fiber rather than copper. This design enables end-to-end optical signal transmission, avoiding the conversion between electrical and optical signals at the switch port level. They can function as core, aggregation, and access devices on campus networks and connect to upstream and downstream devices. One of the most promising developments is the all-optical network (AON), a network architecture designed to carry information entirely in the optical domain without frequent conversions between optical and electrical signals. The global optical switch market reached $5. 5 billion in 2024 and is projected to hit $12.
