Abstract: Embodiments include transistor-outline packages, methods, optical sub-assemblies, and optical modules associated therewith. In some embodiments a transistor-outline package includes a transistor base, a transistor cap, a first lens, a light filtering assembly, a lens assembly, a first optical receiving chip, and a second optical receiving chip. The transistor base and the transistor cap are fastened to form an accommodation cavity. The first lens is disposed on the transistor cap, and the first optical receiving chip and second optical receiving chip are disposed on the transistor base. The lens assembly includes a second lens and a third lens. The light filtering assembly is disposed between the first lens and the lens assembly. The transistor-outline package receives and collimates a first light ray by using the first lens on the transistor cap, and the light filtering assembly splits the first light ray into a second light ray and a third light ray.

Abstract: An optical communication device includes two optical transmitting devices, two optical receiving devices, an optical path component, and an optical fiber adapter. A first converging lens packaged in each of the optical transmitting devices converges a light beam emitted by a light source, and provides the converged light beam for the optical path component. A second converging lens packaged in each of the optical receiving devices converges a light beam from the optical path component, and provides the converged light beam for a photoelectric detection element. The optical path of the optical communication device is simplified and the process costs are reduced. In addition, the quantity of used lenses is reduced, correspondingly reducing the quantity of optical coupling dimensions between mechanical parts and improving production efficiency of combined passive optical network (Combo PON) products.

Abstract: Embodiments of this application provide a communication method and apparatus. The apparatus includes a receiving module and a sending module. When the receiving module receives a user equipment UE capability query message sent by a network device, the sending module sends a first UE capability message (including a first UE capability specification) to the network device, and when determining that a network exception occurs, sends a second UE capability message (including a second UE capability specification that is lower than the first UE capability specification) to the network device. This helps implement mutual compatibility between the terminal device and the network device, thereby ensuring that a communication link can be quickly established between the terminal device and the network device. In this way, a user can normally use the terminal device, and the terminal device can keep using a high-standard network as much as possible, thereby improving user experience.

Abstract: A terminal device includes an application layer, an operating system layer, a hardware driver layer, and a hardware layer. The operating system layer includes a hardware abstraction layer, and the hardware layer includes a master chip and a television receiver chip. The hardware abstraction layer is disposed between the hardware driver layer and the player application at the application layer, so that the hardware abstraction layer shields the player application from an interface difference of television receiver chips, and provides a unified interface protocol between the player application and the television receiver chip, to be compatible with and support television receiver chips with different interfaces.
