Abstract
A simple, cost-effective, centrally controlled, self-protection, colorless wavelength division multiplexing passive optical network is proposed. By using an optical switch at the optical line terminal and an N×N arrayed waveguide grating at a remote node, it can provide 1∶1 protection for downstream traffic and 1+1 protection for upstream data, respectively. The scheme feasibility is verified with 1.25  Gb/s for upstream and 2.5  Gb/s for downstream data rates based on gain-saturated reflective semiconductor optical amplifier, in both normal working and protection modes. The network performance in terms of complexity and availability is also evaluated.
