PURPOSE: A multi-wavelength optical transmitting module using a VCSEL(Vertical Cavity Surface Emitting Laser) and an optical transceiving module thereof are provided to implement low noise and stalbe high speed modulation as a circular and symmetric output mode is supplied by using the VCSEL for the multi-wavelength optical transmitting module. CONSTITUTION: A multi-wavelength optical transmitting module(10) using a VCSEL includes a housing(110), a connection unit(130), a first VCSEL(150), and a second VCSEL(170). The connection unit is connected with a multimode optical fiber. The first and the second VCSELs are fixed to the housing. The first and the second VCSEL emits optical signals having different wavelengths to the multimode optical fiber through the connection unit.
