Abstract

An optical packet switch designed for asynchronous operation is analyzed and simulated. The switch design is cost optimized, with only two stages of tunable wavelength converters, standard demultiplexers designed for wavelength-division multiplexing (WDM), and one single arrayed waveguide grating router used. The switch can be rearranged to be nonblocking, but performs without buffers almost like a strictly nonblocking switch, where the allowed traffic load is limited primarily by output contention. The switch is scalable and upgradeable in the sense that any number of input and output fibers is allowed, up to the number of WDM channels available on a fiber.
