Abstract: Embodiments of the present invention disclose a fiber recognition method, an optical line terminal, and a system. The method includes: obtaining, by an optical line terminal, identification information of a fiber connected to an optical line terminal and to be recognized; generating, by the optical line terminal, a data frame that includes the identification information of the fiber to be recognized; transmitting, by the optical line terminal, optical signals that are generated according to the data frame to the fiber to be recognized, so as to make a fiber recognition instrument implement identification for the fiber to be recognized. The present invention can implement fiber recognition easily and conveniently. When a new ONU user is added to a distributed network, service interruption can also be avoided for a user who is normally using a service, and the cost is low.

Abstract: The present disclosure relates to passive optical network (PON) systems, optical line terminals (OTLs), and optical network units (ONUs). One example PON system includes an OLT and at least two ONUs. The OLT and the 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 used to control each ONU to send upstream data. Each 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. 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 enabled on the second upstream channel.
