PROBLEM TO BE SOLVED: To provide a WDM optical transmission device which can suppress the occurrence of FWM without being restricted by a specific modulation method.;SOLUTION: The WDM optical transmission device includes an electro-optic conversion means 102 which converts a plurality of input electrical signals into optical signals having different wavelengths and outputs them; and a coding means 101 which is provided in a previous stage of the electro-optic conversion means 102 and changes the value of one of bits of electrical signals corresponding to predetermined optical signals having wavelengths adjacent to each other, out of the optical signals output from the electro-optic conversion means 102, when the bits have values which turn on the optical signals at the same time.;COPYRIGHT: (C)2009,JPO&INPIT
