Abstract
A star-shaped coupler for distributing the light signal emitted by any one of input-output devices among the other devices is disposed among these devices. The coupler comprises a plurality of single-core optical fibers for branching purposes. Each one end of those branching fibers whose number is less than the number of the input-output devices by one is bound together and is opposed to the end surface of the output single-core fiber for one of the input-output devices. The other end surfaces of the branching fibers are opposed to their respective end surfaces of the input single-core fibers for the other input-output devices. The end surfaces of the output fibers for the other input-output devices are connected with the end surfaces of the input fibers through the branching fibers. The other ends of the branching fibers which are opposed to their respective end surfaces of the input fibers are bound together to form bound portions corresponding to the input fibers.
