PROBLEM TO BE SOLVED: To attain large scale processing without the use of a large scale optical switch, while suppressing the increase in crosstalks. SOLUTION: The system is provided with a path unit 12 that distributes an optical signal received from a first input port 16 or a second input port 20 to a first output port 18 or a second output port 22, a connection unit 14 that distributes an optical signal which is received from a third input port 24 to a third output port 26, a first optical connection means 28 that connects the 2nd output ports and the third input ports without duplicate to connect each path unit to each connection unit respectively, and a second optical connection means 30 that connects the third output ports and the second input ports without duplicate and connects each connection unit to each path unit. |
