Abstract:
1. An optical switching apparatus that receives optical signals from a plurality of input circuits and outputs the optical signals to an arbitrary one of a plurality of output circuits, comprising: an optical signal adjusting unit for adjusting the optical signals after being received at the plurality of the input circuits to generate an adjusted optical signal; an optical signal switching unit connected to said optical signal adjusting unit for switching the adjusted optical signal to one of a first output port and a second output port; a first optical signal monitoring unit connected to said optical signal switching unit for monitoring the optical signal sent to said first output port; a second optical signal monitoring unit connected to said optical signal switching unit for monitoring the optical signal sent to said second output port; and a controlling unit connected to said optical signal adjusting unit, said optical signal switching unit and said first and second output signal monitoring units for controlling said optical signal adjusting unit based upon an output signal, the output signal being sent from said first optical signal monitoring unit if the optical signal is sent to the first output port, the output signal being sent from said second optical signal monitoring unit if the optical signal is sent to the second output port.
