摘      要：In this paper, we present the evolution of reconfigurable optical add drop multiplexer（ROADM） technologies, and compare three main ROADM architectures available on the market today. Three archhectures include broadcast-select and demux-switch-mux[and the integrated version planar lightwave circuit（PLC）] and wavelengths-selective switch.
