Disclosed are a reflection-type passive optical tag, an optical read/write device and an intelligent optical distribution network. The passive optical tag comprises: an optical receiver, an optical reflector, a chip, and a photovoltaic cell. The optical receiver is connected to the chip, and is configured to receive an optical signal, convert the optical signal into an electrical signal, and send the electrical signal to the chip. The chip is configured to process the electrical signal, store tag information, and control the optical reflector to reflect or absorb a continuous light sent by the optical read/write device, so as to send a signal to the optical read/write device. The optical reflector is connected to the chip, and is configured to be controlled by the chip to reflect or absorb the continuous light. The photovoltaic cell is arranged to convert light energy into electrical energy and store the electrical energy, and provide the electrical energy to the optical receiver, the optical reflector, and the chip. A contactless-type passive optical tag is implemented by the present invention. |
