Abstract: 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.

Abstract: This application provides an optical component including a base, a light splitting structure, a first filter, and a collimation lens, where a first optical signal on a first path is incident on a light splitting surface of the first filter through a light inlet/outlet; the light splitting surface of the first filter reflects the first optical signal to the collimation lens along a second path, where the collimation lens disposed on the second path is configured to convert the first optical signal on the second path into parallel light; and the first optical signal includes a signal of at least one type of wavelength, and the light splitting structure is disposed on an emergent path of the first optical signal after the first optical signal passes through the collimation lens, and is configured to output, based on the wavelength type, the first optical signal adjusted by the collimation lens.

Abstract: The present disclosure relates to message transmission methods in a PON system. One example method includes sending, by an optical line terminal (OLT), a first message to an unregistered optical network unit (ONU), where the first message includes at least one piece of indication message, and one piece of indication message of the at least one piece of indication message indicates a first power range and a first time range associated with the first power range, and receiving, by the OLT in the first time range, a registration message sent by the ONU, where a downstream receive power of the ONU falls within the first power range.
