An optical switch circuit network includes r input optical switches 102a each having n input ports, m 1xr optical switches 125a, and an nxm optical switch for switching a path connecting the input ports and the 1xr optical switches, and r output optical switches 125 each having rx1 optical switches, n output ports, and an mxn optical switch for switching a path connecting the output ports and 1xr optical switches. The i-th 1xr optical switch of each input optical switch is connected to the i-th rx1 optical switch of each output optical switch.
