PROBLEM TO BE SOLVED: To easily switch respective channels of multiple wavelength light signals for each wavelength by respectively relating input and output photocouplers to the correspondent input and output photocouplers of an optical switch and controlling the transmitting operation mode and reflecting operation mode of fiber grids. SOLUTION: An optical cross connector 300 receives K pieces of multi- wavelength light signals respectively having the channels of different wavelengths, routes the respective channels of multiple wavelength light signals between K pieces of cross connect inputs and M pieces of cross connect outputs and outputs M pieces of multiple wavelength light signals. As a K×1 star coupler, having K pieces of input ports and a single output port, an output photocoupler 320 is related to respective cross connect output ports 315. An input photocoupler 310 and an output photocoupler 320 are mutually bonded through a mutual connection wavelength selective optical fiber 325, and the wavelength selective optical fiber 325 transmits or reflects one of respective wavelength channels of multiple wavelength light signals. |
