Full-mesh WDM network system: AWG-STAR

We have established a simple full-mesh network system (AWG-STAR) by using wavelength division multiplexing (WDM) technology and a cyclic-frequency arrayed waveguide grating (AWG) router. N x N full-mesh interconnection isrealized based on only N wavelengths routing at optical layer. High bit rate optical signals with any protocols are processed by wavelength routing with low latency. The system is scalable up to a 100-node system with a petabit throughput.
