The first to the Nth wavelength demultiplexer(30) demultiplex the input 1 to input N, respectively. Optical couplers(40) couple outputs of the wavelength demultiplexers(30) with path monitoring information generated by a path monitoring information generator. Optical switches(50) switch optical signals coupled in the optical couplers(40) according to pre-set switching information. Wavelength multiplexers(60) receive signals transmitted from the optical switches(50) and multiplex them. Optical circulators(70) detect path monitoring wavelength from path monitoring information-coupled data outputted from the wavelength multiplexers(60). Optical receivers(80) convert the path monitoring wavelength detected from optical circulators(70) into an electric signal. Optical fiber grids(90) generate output 1 to output N. The ith frequency and time slot detector(150) detects the ith frequency and a tie slot from the electric signal. A comparator(140) compares previously stored routing/switching information and calculated movement path monitoring information. If a path has an error, a switching controller(130) corrects the error by controlling switching of the optical switches(50).
