ABSTRACT:
In the optical network system, light input to any of the optical input ports of the optical coupler is converted into light at another wavelength via a variable-wavelength optical receiver and an optical sender, and is then reinput to the optical coupler. This arrangement makes it possible to realize a full-mesh optical network system with a simple construction at low costs.
