Abstract
Disclosed is a multi-wavelength transmission apparatus including a wavelength divider to divide an optical signal by wavelength and output wavelength-divided optical signals to different positions, the optical signal being received from an optical circulator, a first cylindrical lens to diverge the wavelength-divided optical signals along an X axis and a Y axis and allow the wavelength-divided optical signals to be promoted in a Z-direction, a second cylindrical lens to diverge optical signals output from the first cylindrical lens along the X axis and the Y axis and allow the output optical signals to be promoted in the Z-direction, and a reflector to reflect optical signals output from the second cylindrical lens toward the second cylindrical lens, the first cylindrical lens being identical in shape to the second cylindrical lens and rotated by 90° in an Y-axial direction based on the second cylindrical lens.
