Abstract

PURPOSE:To reduce the loss at the terminal in the optical transmission of the star coupler by forming both the optical transmission and reception semiconductor elements of each data terminal unit on the same substrate and with the same optical path. CONSTITUTION:Single-core optical fiber cable 12 is led out from star coupler 11 which is formed by adhering close the areas of plural optical fibers thinned gradually, and data terminal unit 13 is coupled optically to each cable. And both the optical and reception systems to be installed to unit 13 are formed on the same semiconductor substrate with the same optical path. When the data is transmitted to #2 from
