Optical switch is an optical device having one or more optional transmission ports for physically switching or logically operating an optical signal in an optical transmission line or an integrated optical path.The switch consists of two ports that selectively transmits, redirects, or blocks optical power in a fiber optic transmission line.Unifiber build it as 1xN Optical switch , 2xN Optical switch , 4xN Optical switch.
