RECEIVER AND TRANSMITTER

摘要

PROBLEM TO BE SOLVED: To provide a receiver and the like capable of preventing deterioration of transmission characteristics due to occurrence of dip.SOLUTION: The receiver includes: an optical filter; an acquisition section; a first determination section; and a filter setting section. The optical filter transmits an optical DMT signal received from a transmitter. The acquisition section acquires transmission characteristics of the optical DMT signal received from the transmitter. The first determination section determines the filter frequency on an optical filter for removing a dip from the optical DMT signal based on the acquired transmission characteristics. The filter setting section sets the determined filter frequency to the optical filter.SELECTED DRAWING: Figure 1
