PURPOSE:To simplify the branching, synthesizing or switching of light by previously connecting a means to colimate optical beams through a colimating lens on the way of an optical transmission line and inserting a parts having a light branching, synthesizing or switching function into the means. CONSTITUTION:An optical plug socket colimates the light from an optical fiber 1 through a colimating lens 2, reflects the parallel beam through a prism 3 and collects the reflected light through a colimating lens 2'' to form an optical path coupled with an optical fiber 1'. When an expanding terminal 7 is to be connected to the optical plug socket, optical connectors 6 are connected to optical fibers 1'', 1''', the connectors 6 are inserted into a case 4 and the prism 3 is removed from the light path by depressing a pushbutton or the like, so that the light from the optical fiber 1 is inputted to the terminal 7 through the colimating lenses 2, 2' and the light from the optical fiber 1''' is connected to the optical fiber 1' through colimating lenses 2''', 2''. In the same manner, light can be easily branched, synthesized or switched. |
