Abstract: A method for implementing a variable optical splitter and a variable optical splitter are provided. The method includes that: the variable optical splitter is divided into one or more virtual optical splitting units according to wavelengths/wavebands of optical signals, wherein the virtual optical splitting units and the wavelengths/wavebands are in a one-to-one correspondence, and moreover, the wavelengths/wavebands and splitting ratios are also in a one-to-one correspondence; and optical guiding or optical splitting is performed on the incident optical signals through the virtual optical splitting units. By adopting the technical solutions provided by the present disclosure, the technical problems that there is yet no optical splitter with a variable splitting ratio in the related technology and the like are solved, and controllability of the splitting ratios of the optical splitter is achieved.

Abstract: The disclosure relates to the technology of optical communication, and specifically, to a passive photoelectric tag. The passive photoelectric tag includes: an photocell used to receive an optical signal; a service separation unit used to separate the received optical signal into a DC voltage and an AC signal; a transceiver unit used to perform photoelectric conversion and electric signal processing on an optical signal in the AC signal under power supply of the DC voltage to generate a signal to be transmitted; and an LED emission unit used to transmit the signal to be transmitted in a form of an optical signal. The passive photoelectric tag realizes power provision and signal receiving through a photocell, and power supply is not needed, the cost and the size of the passive photoelectric tag is reduced and the service life of the passive photoelectric tag is prolonged.
