摘要： The Ethernet switch for an optic fiber network includes: a first light emitter designed to transmit a light signal in the optic fiber, first photodetector configured to transform a light signal coming from the optic fiber into an electric signal, at least one communication port of electric signals with a terminal, a power supply circuit configured to supply power to the light emitter and to the first photodetector, a wake-up circuit connected to the first photodetector and to the communication port 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 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 communication port.

摘要： The position detector of an object includes a body defining an input receiving an optical fibre delivering a light signal, and an output delivering a signal representative of the position of the object. A mirror is mounted to move between first and second positions in the body with respect to the input. The first position or the second position ensures transmission of the light signal from the input to the output. The other of the first position and the second position prevents transmission of the light signal to the output. A spring is mounted in the body in order to place the mirror in the first position. A tip is movable relative to the body between a first position and a second position along a direction of movement and is intended to cooperate with the object to be monitored.
