Abstract
An optical asynchronous transfer mode ATM switch for recovering the limitation of processing capacity and performing large capacity of switching is disclosed. The ATM switch includes wavelength division multiplexing/time division multiplexing conversion modules for demultiplexing wavelength multiplexed optical channels through transmission links of respective input terminals of a switch to convert them into a primary wavelength for routing to their respective channels and compressing to time division multiplexing for preventing collision between cells, a first router for routing the respective cells which are converted into a primary wavelength by the wavelength division multiplexing/time division multiplexing conversion modules to assign the first destination, time division multiplexing/wavelength division multiplexing conversion modules for demultiplexing the channel signals routed by the first router, decompressing into original signals to convert them into wavelength to be routed for final destination and compressing them again to prevent collision between cells, and second routers for routing the decompressed signals from the time division multiplexing/wavelength division multiplexing conversion modules to the final destination.
