ABSTRACT:
An optical communication system has a plastic optical fiber (POF) and an optical communication module. The POF has a spherical end surface, and light emitted from the spherical end surface has an NA of 0.35 or lower. The POF is installed in the module such that a light receiving surface of a light receiving element (PD) is at a distance, d, from an apex of the spherical end surface. The distance, d, is within a range of 0<d≦r*D/(n−n1) when a PD diameter is not larger than D, and within a range of D≦d≦r*D/(n−n1) when the PD diameter is larger than D, where D is a diameter of the POF, r*D is a radius of curvature of the spherical end surface, n is a refractive index of a core of the POF, and n1is a refractive index of a substance between the spherical end surface and the PD.
