An (OPS-M)-based WDM-PON with functions of wavelength tri-reuse and all-sided fiber protection

In this paper, an optical power splitter module (OPS-M) and (OPS-M)-based WDM-PON are proposed. The symmetry and passivity of OPS-M makes it easy to integrate and dirt cheap in practice. It shows this OPS-M can be widely applied in an optical network. By utilizing the OPS-M, the wavelength tri-reuse is realized. At the same time, the coherent interference can also be eliminated due to cross-wavelength reuse. By introducing matrix operations and orthogonal vector group, the relations among wavelengths, optical network units and their services are shown clearly. By designing structure of ONU, feeder fiber and distributed fiber failures can be self-protected. Besides, the ONUs remain colorless and the system has passivity. By the simulation, feasibility of the scheme is demonstrated.
