PROBLEM TO BE SOLVED: To adequately compensate distribution even when a signal transmission speed is increased and a signal transmission band width is enlarged. SOLUTION: The optical communication equipment to carry out the wavelength division multiplexing of the signals of a plurality of signal transmission bands is provided with first optical means (16, 19, 20:36, 44, 45:26, 54, 55) which have a property for compensating the dispersion of a transmission channel to which the optical communication equipment is connected, and carry out distribution Raman amplification in at least one transmission band of the plurality of signal transmission bands. |
