<p>PROBLEM TO BE SOLVED: To provide a compact optical multiplexing device.SOLUTION: A second optical fiber 120 has a plurality of cores 122. A plurality of first optical fibers 110 is optically connected with different cores 122 at one end 124 of the second optical fiber 120. A lens member 130 is provided to face another end 126 of the second optical fiber 120. A third optical fiber 140 is located such that one end 144 thereof faces the other end 126 of the second optical fiber 120 with the lens member 130 in between. The one end 144 of the third optical fiber 140 is preferably located at a focal point of the lens member 130.</p> |
