A novel access/metro network architecture based on a coarse wavelength division multiplexing array waveguide grating router, supporting multiple passive optical networks (PONs) in the downstream and switching up to 32 optical network units (ONUs) per PON over coarse wavelength bands is described. The cost effective network architecture is simulated, using a physical-layer model of two PONs, each comprising 16 ONUs, employing 12nm-wide passband windows in the array waveguide grating. In this manner low error rate transmission at 2.5 Gbit/s for distances up to 20 km is demonstrated.
