Abstract: A data transfer method includes that a first device displays a first interface. The first interface includes image information of a first file. When a distance between a Near-Field Communication (NFC) chip of the first device and an electronic tag of a second device is less than a preset threshold, the first device obtains a BLUETOOTH address of the second device. The electronic tag includes device information of the second device, and the device information includes the BLUETOOTH address or a tag identifier (ID) used to obtain the BLUETOOTH address. The first device exchanges a WI-FI connection parameter with the second device through a BLUETOOTH connection corresponding to the BLUETOOTH address. The first device establishes a WI-FI connection to the second device. After the WI-FI connection is established, the first device automatically transfers the first file to the second device through the WI-FI connection.

Abstract: Embodiments are provided for a novel multi-wavelength coherent receiver (MWCR) design and operation capable of detecting multiple optical wavelength channels. The embodiments include an optical receiver comprising a polarization-diversity optical hybrid module, a multiple wavelength local oscillator (MWLO) coupled to an input of the polarization-diversity optical hybrid module, a plurality of PIN diodes coupled to the polarization-diversity optical hybrid module, a plurality of analog-to-digital converters (ADCs) coupled to the PIN diodes, and a digital signal processing (DSP) module coupled to the ADCs. The polarization-diversity optical hybrid module splits an optical signal into multiple polarization components, wherein the optical signal includes multiple channels at multiple wavelengths. The MWLO locks the optical signal to the multiple wavelengths of the channels simultaneously. The DSP combines the signals from the ADCs corresponding to the polarization components and detects the channels at the wavelengths.

Abstract: This application provides a model training-based communication method and apparatus, and a system, to effectively decrease a data amount of a parameter transmitted between the communication device and the central server. The method includes: The communication device determines a change amount of a first model parameter value. If the communication device determines, based on the change amount of the first model parameter value, that a first model parameter is stable, the communication device stops sending an update amount of the first model parameter value to the central server in a preset time period. The update amount of the first model parameter value is determined by the communication device based on user data in a process of performing model training. The communication device receives a second model parameter value sent by the central server.
