An optical branching apparatus in which a pair of optical transmission lines as reverse and forward links are branched into a plurality of lines includes a plurality of wavelength demultiplexing ports and a plurality of optical transmission media. The plurality of wavelength demultiplexing ports have wavelength demultiplexing/multiplexing units each connected to a branch point of each of the optical transmission lines to demultiplex a light beam having different wavelengths from the each optical transmission line and output demultiplexed light beams to branch destinations, and to transmit light beams having different wavelengths and input from branch sources and output a multiplexed light beam to the each optical transmission line. The plurality of optical transmission media connect the wavelength demultiplexing ports corresponding to the reverse link and the wavelength demultiplexing ports corresponding to the forward link in accordance with wavelengths of light beams which are used depending on a normal state and occurrence of a failure.
