Claim 0:
1. A photo-electron fusion switch that includes a packet switch and an optical device and is connected to nodes of a communication source and a communication partner, wherein
the packet switch includes an electronic circuit and a plurality of optical transmit and receive components each having a photoelectric conversion function and provided in a vicinity of the electronic circuit,
a route connecting the electronic circuit and the plurality of optical transmit and receive components is wiring through which electric signals pass,
a route connecting the plurality of optical transmit and receive components and the optical device and a route connecting the optical device or the plurality of optical transmit and receive components and input-output ports of the photo-electron fusion switch are optical waveguides, and
the plurality of optical transmit and receive components configured to transmit and receive optical signals different in transmission speed to and from the nodes of the communication source and the communication partner, and are configured to input the optical signals transmitted from the nodes, output converted electric signals to the electronic circuit, and transmit optical signals obtained by converting electric signals output from the electronic circuit to the nodes, wherein
the optical device is an optical relay switch that inputs respective optical signals output from specific locations of the plurality of optical transmit and receive components, folds back the optical signals by another route, and transmits the optical signals to other specific locations of the plurality of optical transmit and receive components, and
the plurality of optical transmit and receive components can support coherent communications, and connect optical signals obtained by converting electric signals whose transmission speed is a specific amount to the optical relay switch.
