Large capacity optical atm switch

Relates to: (Asynchronous Transfer Mode ATM) a large-capacity optical asynchronous transfer mode switch to also overcome the limitation of the processing capacity of the switch, as well as to perform the switching of the high-capacity, the present invention provides an optical Asynchronous Transfer Mode The present invention is a wavelength division multiplexing / time division multiplexing of time-division multiplexed by demultiplexes the wavelength-multiplexed optical channels via the respective input terminals of the transmission links of the switch converting the first wavelength for a path assigned to each channel and compressed in order to prevent a collision between the cells conversion module and the wavelength division multiplexing / time division the first path to the first wavelength converting each cell in a multiplexing conversion module routing to the primary destination baejeonggi and, to the first demultiplexes the channel signal assigned to the path baejeonggi original compression time division multiplexing / wavelength division multiplexing switching module, and irreversible compression in the time-division multiplexing / wavelength division multiplexing switching module after the irreversible compression to the signal format by converting the wavelength to be routed to a final destination in order to prevent the cell collision again the characterized by the adapted cells the signal to the final destination in the second path for routing baejeonggi All.
