Abstract: The present invention provides a WDM which includes three ports, the three ports each include an optical fiber array and a micro lens array matching the optical fiber array; an optical signal is transmitted to a filter after passing through a corresponding micro lens in a first micro lens array of the common port; transmitted light of the optical signal enters a corresponding micro lens in a second micro lens array of the pass port after passing through the filter, and then the light is output by a corresponding optical fiber in a second optical fiber array of the pass port; reflected light of the optical signal enters a corresponding micro lens in a third micro lens array of the reflection port after being reflected by the filter, and the light is output by a corresponding optical fiber in a third optical fiber array of the reflection port.
