1. An optical network system comprising:
N (N is an integer equal to or greater than 2) information processing terminals each including an optical transmitter unit and an optical receiver unit;
N first optical fibers extending from the respective optical transmitter units of the N information processing terminals;
N first optical transmission lines connected to the respective first optical fibers at one ends;
N second optical fibers extending from the respective optical receiver units of the N information processing terminals;
N second optical transmission lines connected to the respective second optical fibers at one ends;
an optical coupling unit configured to couple another ends of the N first optical transmission lines to one end of a third optical transmission line; and
an optical branching unit configured to couple another end of the third optical transmission line to another ends of the N second optical transmission lines.
