ABSTRACT:
A wavelength-multiplexing connector and a transmitting/receiving part can be easily connected to and disconnected from each other. The wavelength-multiplexing connector comprises a single optical fiber, through which a plurality of optical signals having different wavelengths are transmitted, and a wavelength-multiplexer optically coupled to the optical fiber and capable of optically separating an optical signal having a particular wavelength out of the plurality of optical signals. The wavelength-multiplexer comprises a wavelength division multiplexing filter disposed at a midway of a first light waveguide, and a multilayered film mirror for reflecting, at a midway of a second light waveguide, a signal separated by the wavelength division multiplexing filter.
