    Abstract: A housing for packaging an optical transmitter module includes a body, a focusing structure, a first three-dimensional (3D) optical waveguide, and an optical fiber interface. The optical fiber interface is located inside the body and configured to accommodate a single-mode optical fiber. The first 3D optical waveguide is embedded in the body. The focusing structure is configured to receive a first single-mode optical signal and enable the received first single-mode optical signal to be focused for a first time at a focal point of the focusing structure. The first 3D optical waveguide is configured to receive the first single-mode optical signal, and output the first single-mode optical signal to the single-mode optical fiber. The focal point of the focusing structure coincides with an input end of the first 3D optical waveguide.

    Abstract: This application provides example encoding methods and example encoders. One example method includes performing bit truncation on a to-be-encoded block when a bit rate control condition is satisfied. A first cost value corresponding to the bit truncation can then be calculated. The to-be-encoded block can then be predicted to determine a prediction residual of the to-be-encoded block when the bit rate control condition is satisfied. A second cost value corresponding to the prediction can then be calculated based on the prediction residual. The first cost value can then be compared with the second cost value to determine an encoded bit.

    Abstract: Embodiments of this application provide an information obtaining method and a terminal device. The method is applicable to a device having a wireless fidelity Wi-Fi function. When the terminal device cannot be connected to a cellular network, the method includes: The terminal device configures at least one first channel and a transmit power of each first channel, searches for an access point device on a corresponding first channel by using a configured transmit power, completes an access connection to a found access point device, obtains a current geographic location of the terminal device based on a media access control MAC address of the access point device connected by the terminal device, and obtains country information (for example, a country code) based on the geographic location. Alternatively, the terminal device locates a current geographic location of the terminal device by using a built-in positioning module, and obtains corresponding country information (for example, a country code) based on the geographic location, so that the terminal device subsequently configures a correct transmit power and a correct channel for Wi-Fi based on the country code.
