The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: This application discloses a PON system, an OLT, and an ONU, and relates to the optical communications field. The PON system includes an OLT and at least two ONUs, and the OLT and the at least two ONUs exchange data on one downstream channel and two upstream channels. The OLT sends downstream data to each ONU on the downstream channel, where the downstream data includes an upstream bandwidth grant, and the upstream bandwidth grant is used to control the ONU to send upstream data; the ONU receives the downstream data on the downstream channel, and sends the upstream data on a first upstream channel or a second upstream channel based on the upstream bandwidth grant included in the downstream data; and the OLT receives, on the first upstream channel and the second upstream channel, the upstream data sent by each ONU, where a registration function is disabled on the first upstream channel, and the registration function is enabled on the second upstream channel.
