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. Port types are limited to two: optical and Ethernet. The principle is that the light enters the light-sparse medium from the light-dense medium, resulting in total reflection. Usually, there are several types such as SC, ST, FC, etc.
