Abstract: A data transmission and reception method and device are provided. The data transmission method includes: determining wavelength channels for data to be transmitted according to received wavelength channel information of an optical network unit (ONU); dividing the data to be transmitted in a sequence according to the number of the wavelength channels to obtain data packets; identifying the data packets according to the division sequence to obtain sequence identifiers of the data packets; and encapsulating the data packets into downstream frames of the wavelength channels in a one-to-one correspondence according to the sequence identifiers of the data packets, and transmitting the downstream frames of the wavelength channels separately to the ONU.

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.
