Abstract
A receiving device includes an optical filter, an acquisition unit, a first determination unit, and a filter setting unit. The optical filter transmits an optical DMT signal received from a sending device. The acquisition unit acquires the transmission characteristics of the optical DMT signal received from the sending device. The first determination unit determines a filter frequency of the optical filter that removes a dip from the optical DMT signal on the basis of the acquired transmission characteristics. The filter setting unit sets the determined filter frequency in the optical filter.
