Optical and electronic integrated switch

A optical and electronic integrated switch comprising a packet switch and an optical switch, wherein

• the packet switch includes an electronic circuit and a plurality of optical transceivers provided near the electronic circuit and having a photoelectric conversion function,
• paths connecting between the electronic circuit and the plurality of optical transceivers are formed of wiring through which an electrical signal passes,
• a plurality of optical waveguides are connected to an input side and an output side of the optical switch,
• part of the plurality of optical transceivers have a regeneration function that, using the photoelectric conversion function, converts an inputted optical signal into an electrical signal by signal conversion, turns back the electrical signal and converts the electrical signal into an optical signal by signal conversion, and outputs the optical signal, and the part of the plurality of optical transceivers have optical waveguides that are configured such that at least part of the input sides of the part of the plurality of optical transceivers are connected to part of the plurality of optical waveguides on the output side of the optical switch, and that at least part of the output sides of the part of the plurality of optical transceivers are connected to part of the plurality of optical waveguides on the input side of the optical switch, and
• optical waveguides are used for paths for connecting, to input and output ports of the optical and electronic integrated switch, the input and output of the optical transceivers not having the regeneration function, the input and output of the optical transceivers having the regeneration function but not connected to the optical waveguides, and the plurality of optical waveguides for the optical switch, not connected to the optical waveguides.
