In practical applications, a plurality of beams of light with different wavelengths are respectively transmitted or reflected through the plurality of input optical fibers 11 and the plurality of input lenses 12 to the plurality of diaphragms 21, and then output through at least one output lens 32 and the corresponding output optical fiber 31. On this basis, the user can freely adjust the combined output form, the output sequence and the number of the used output fibers 31 among the plurality of beams of light based on the wavelength by correspondingly configuring the transmission or reflection of the plurality of beams of light having different wavelengths when passing through the plurality of diaphragms 21, respectively.
