Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. The photonics-electronics convergence switch according to claim 3, wherein
at least some of the optical transmitter-receivers have a regeneration relay function that converts an inputted optical signal into an electrical signal by optical-electrical conversion, turns back the electrical signal and converts the electrical signal into an optical signal by electrical-optical conversion, and outputs the optical signal, and
each of the optical transmitter-receivers having the regeneration relay function receives input of an optical signal outputted from one of the optical-relay-input-path setting switch and the optical-relay-output-path setting switch included in at least one of the pairs composed by combining the pair of the optical-relay-input-path setting switches and the pair of the optical-relay-output-path setting switches, the one of the pairs being farther from the packet switch, converts the optical signal into an electrical signal by the optical-electrical conversion, turns back the electrical signal and converts the electrical signal into an optical signal by the electrical-optical conversion, and inputs the optical signal into the one of the optical-relay-input-path setting switch and the optical-relay-output-path setting switch.
