Abstract
An optical communication module for optical wavelength division multiplexing includes a plurality of light devices emitting or receiving light beams having different wavelengths, a single optical fiber, and an optical elements arranged between the plurality of light devices and the single optical fiber and having a plurality of lens areas to converge a light beam starting from a single point at a plurality of points or light beams starting from a plurality of points at a single point. In the optical communication module, the plurality of lens areas are arranged such that the center points of the plurality of lens areas are located at the same distance from a point, and the single point and the plurality of points are located at the opposite sides with respect to the optical element.
