摘要： The present disclosure relates to information transmission methods in a passive optical network (PON) system. One example method includes sending, by an optical line terminal (OLT), a first power range and time indication to an unregistered optical network unit (ONU), where the first power range and the time indication indicate the ONU to send a serial number of the ONU to the OLT at a time indicated by the time indication in case a downlink receive power of the ONU is within the first power range, and receiving, by the OLT, the serial number of the ONU.

摘要： Embodiments of this application provide an OLT, an ONU, and a system. In a downlink direction, the first OLT is configured to convert received downlink data packets of M1 paths into one downlink optical signal whose wavelength is λo, and the first ONU is configured to receive the downlink optical signal, and output a target user data packet after processing the downlink optical signal. In an uplink direction, the first ONU is configured to convert received uplink data packets into an uplink optical signal whose wavelength is λi, and the first OLT is configured to receive a plurality of uplink optical signals of different wavelengths, and output user data packets of a corresponding quantity of paths after processing.

摘要： A computer-implemented method for automated operation of network devices within a home communication network includes detecting actuator actions for a plurality of actuators within the home communication network, each actuator of the plurality of actuators configured to change a state of at least one network device. The detected actuator actions are correlated with one or more sensor values from a plurality of sensors within the home communication network to generate configuration data. The configuration data includes a trigger graph with one or more trigger conditions and an action graph corresponding to the trigger graph. The action graph indicates one or more actuator actions associated with at least one actuator of the plurality of actuators. Upon detecting a trigger condition of the one or more trigger conditions, the at least one actuator of the plurality of actuators is triggered to perform the one or more actions indicated by the action graph.

摘要： 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.
