PURPOSE:To reduce the difference among distributed light quantities and at the same time to simplify the structure and production for an optical communication element, by projecting plural input/output fibers within a container having a scattering coating applied on a spherical surface. CONSTITUTION:When an optical signal is applied to an input optical fiber 3, the incident light is reflected from a reflecting plate 5. This reflected light hits a scattering coating 2 on a spherical surface 1a and is scattered. Thus the approximately equal light quantity is distributed to each output optical fiber 4 of an output optical fiber group. |
