Abstract:
1. An optical communication module for optical wavelength division multiplexing, the optical communication module comprising: a plurality of light devices emitting or receiving light beams having different wavelengths; a single optical fiber; and an optical element arranged between the plurality of light devices and the single optical fiber and having three or more lens areas to converge a light beam starting from a single point P wherein the plurality of lens areas are arranged such that center points of the plurality of lens areas are located at the same distance from a point, and the single point P wherein the wavelength selective member of the optical element comprises three or more filter areas and, of the three or more filter areas, the filter areas for the longest wavelength channel and the shortest wavelength channel are formed of edge filters and at least one filter area for an intermediate wavelength channel is formed of the wavelength selective filter.
