Abstract: A receiver optical subassembly includes an optical receiving housing, and a first optical receiver, a second optical receiver, and a first glass are packaged in the optical receiving housing. The first glass is disposed obliquely relative to an optical receiving direction, and includes a light incident surface and a light emergent surface. The first optical receiver and the second optical receiver are opposite to the light emergent surface of the first glass. A first light splitting film is disposed on the light emergent surface of the first glass. A first reflective film is disposed on the light emergent surface of the first glass. The first light splitting film can transmit an optical signal of a first wavelength and reflect an optical signal of a second wavelength.

Abstract: A communication method includes: a first device determines a first channel access manner based on network status information, wherein the first channel access manner is a carrier sense multiple access with collision avoidance (CSMA/CA) channel access manner or an intelligent channel access manner, and the intelligent channel access manner is a manner of accessing a channel based on a channel access decision obtained by a neural network; and sends data on a channel in the first channel access manner. The first device selects the first channel access manner based on the network status information, and sends the data in the first channel access manner.

Abstract: A parallel transmission method and apparatus to improve channel resource utilization are described. A first configuration parameter for a first access point is configured by a WLAN control device. A second configuration parameter for a second access point is configured by the WLAN control device. The first configuration parameter is used to indicate that the first access point can send a first WLAN frame to at least one station in a first station set at a starting time by using a channel resource. The first station set includes one or more stations associated with the first access point. The second configuration parameter is used to indicate that the second access point can send a second WLAN frame to at least one station in a second station set at the starting time by using the channel resource. The second station set includes one or more stations associated with the second access point.
