Optical switching technology in the all optical communication

Two major component part of the communication network is the transmission and switching, with the demand of capacity of communication and the development of light communication. Because of the limitation of electronic transfer rate becomes the bottleneck of communication in the electrical. Therefore the key technology of all optical communication network was put forward ----Optical Switching Technology. At firstly, the conception, characteristics and classification of the optical switching technology are introduced in this paper. At last, in the paper introduces the development of Optical-Switching-Technology.
