PURPOSE:To prevent each signal from being mixed up together by constituting the titled device so that an area where each optical signal is brought to space propagation adjacently and in parallel can be eliminated, in case when an optical signal for propagating each core is separated into each different fiber, or a different optical signal is made incident on each core. CONSTITUTION:Optical signals 3a, 3b which have arrived by propagating each core 1a, 1b of a multicore fiber F1 are made incident diagonally on fiber end faces 2a, 2b, therefore, deflected to the respective different directions, and made incident on cores 1c, 1d of fibers F2, F3. Accordingly, an area where the optical signal 3a and 3b are brought to space propagation adjacently and in parallel does not exist, therefore, there is scarcely the possibility that the optical signal 3a and 3b are mixed up together, and they are separated from each other and made incident on the cores 1c, 1d of the fibers F2, F3. In case when the optical signal is made incident on each core 1a, 1b of the multicore fiber F1 from the fibers F2, F3, as well, each signal is scarcely mixed up together. |
