PURPOSE: A method for stabilizing multiple optical channel wavelengths is provided to stabilize wavelengths by detecting a ratio of the penetrating characteristics and transmitting a control signal to a transmitting stage. CONSTITUTION: An output ratio of two output terminals with respect to respective optical channels obtained from two wavelength division demultiplexers(4-1,4-2) maintaining the penetrating characteristics is compared with an output ratio value measured by applying an optical source of a known optical wavelength to measure a wavelength of a wavelength division multiplexed optical communication channel, through which the wavelength of the wavelength division multiplexed optical communication channel is constantly maintained. |
