Abstract: Provided is a multi-channel optical module device. The optical module device includes: a light source unit configured to include a plurality of laser diodes that are capable of wavelength modulation according to current; a beam splitter unit configured to include a plurality of beam splitters that have different reflectivity and transmissivity and reflect or transmit light output from each laser diode of the light source unit to output them in a first direction or a second direction; and an optical coupler configured to couple and output the light from the beam splitter unit. Center wavelengths of the laser diodes of the light source unit are different from each other, and the number of output channels varies according to the number of laser diodes.
