Claim 2:
3. The photonics-electronics convergence switch according to claim 2, wherein
each of the optical-input-path selection switches is provided between the input port and a corresponding one of the optical transmitter-receivers,
functions as a through connection to connect between the input port and the corresponding one of the optical transmitter-receivers or connect between the dedicated input port of the one of the pair of the optical-relay-input-path setting switches on the one side and the dedicated output port of the one of the pair of the optical-relay-output-path setting switches on the other side, and
functions as a cross connection to connect between the input port and the dedicated output port of the one of the pair of the optical-relay-output-path setting switches on the other side or connect between the corresponding one of the optical transmitter-receivers and the dedicated input port of the one of the pair of the optical-relay-input-path setting switches on the one side, and
each of the optical-output-path selection switches is provided between a corresponding one of the optical transmitter-receivers and the output port,
functions as a through connection to connect between the output port and the corresponding one of the optical transmitter-receivers or connect the dedicated output port of the one of the pair of the optical-relay-output-path setting switches on the one side and the dedicated input port of the one of the pair of the optical-relay-input-path setting switches on the other side, and
functions as a cross connection to connect between the output port and the dedicated input port of the one of the pair of the optical-relay-input-path setting switches on the other side or connect the dedicated output port of the one of the pair of the optical-relay-output-path setting switches on the one side and the corresponding one of the optical transmitter-receivers.
