摘要： This application provides a port detection method and apparatus. In the technical solutions in this application, an OLT or an ONU may determine, based on at least two wavelengths and a preset correspondence, port information that is of an optical splitter and that corresponds to the ONU. That is, a branch port directly or indirectly connected to the ONU is defined by using the at least two wavelengths. In this way, different branch ports can be distinguished by using combinations of a plurality of wavelengths, to define a large quantity of branch ports of the optical splitter by using free combinations of a small quantity of wavelengths. This helps avoid a problem of an insufficient quantity of monitoring wavelengths due to a limitation of a monitoring wavelength range, and helps accurately determine a connection relationship between an ONU and a branch port of the optical splitter.

摘要： Embodiments of the present invention provide an apparatus and a method for detecting an uplink optical signal. The apparatus includes: a control module and a test module, where the control module is configured to determine a remaining bandwidth in a target uplink frame as a test window, where the remaining bandwidth in the target uplink frame indicates an unallocated bandwidth in the target uplink frame; and the test module is configured to detect an uplink optical signal in the test window determined by the control module. Therefore, a remaining bandwidth obtained after bandwidth allocation in a target uplink frame is used to detect an uplink optical signal, which can effectively use a resource without the need of independently opening a test window and using an extra resource to detect the uplink optical signal, thereby avoiding waste of a resource and improving test efficiency.
