Ethernet switch for fiberoptic network

Ethernet switch for an optic fiber network comprising:

• a first light emitter designed to transmit a light signal in a optic fiber,
• a first photodetector configured to transform a light signal coming from the optic fiber into an electric signal,
• at least one electric communication port configured to communicate electric signals with a terminal,
• a power supply circuit configured to supply power at least to the first light emitter and to the first photodetector,
• a wake-up circuit connected to the first photodetector and to the at least one electric communication port, the wake-up circuit being configured to generate an electric wake-up signal on receipt of a light signal by the first photodetector and/or of an electric signal on the at least one electric communication port, the wake-up circuit being connected to the power supply circuit to trigger power supply of the first light emitter and of the at least one electric communication port.
