PURPOSE:To control switchingly many inputting optical signal lines to a line in an optional direction of many outputting optical signal lines at the same time, by changing the rotating angle of a mirror for changing an inputted selecting signal. CONSTITUTION:When an output selecting signal is applied externally via a signal line 15, a conversion circuit 14 outputs a turning driving signal to a turning driving body 12, which turns a turning shaft 11 of a mirror 10 up to a prescribed angle in response to the inputted turning driving signal. Light making incident and emitting adaptors 131-1-13i-1 are used as an light making incident adaptor and a light is applied to an optical fiber cable connected to the adaptor, then the optical beam made incident from the adaptors 131-1-13i-1 are used as light making incident adaptors and a light is applied to the optical fiber cable connected to them, then the optical beam made incident from the light making incident and emitting adaptors 131-1-13i-1 is reflected on a mirror 10 and applied respectively to light making incident and emitting adaptors 131-3-13i-3. |
