PURPOSE: An optical channel switch for a WDM(Wavelength Division Multiplex) transmission equipment and a control method therefor are provided to increase the flexibility of the operation and structure of a network by adding a switch function to an OADM(Optical Add/Drop Multiplexer) used in the WDM transmission equipment. CONSTITUTION: An optical waveguide combines an input port(411) and an output port(413) with a drop port(412) and an add port(414). A plurality of conductive members(421,422) are allocated on the optical waveguide to be opposite each other. A power supply unit(424) connects each conductive member(421,422) to its each electrode terminal and forms an electric potential difference. A switch element(423) selectively connects and disconnects a power supply path between the power supply unit(424) and the conductive members(421,422).
