Problems solved by technology
However, this solution is technically feasible, but there are two disadvantages or deficiencies: First, in a multi-wavelength channel PON system, the optical module of each wavelength channel needs to add such a built-in top adjustment module, which increases the module volume and Reduce module integration and increase a lot of cost; second, when the initial network ODN construction does not meet the OLT test conditions, the optical path detection function of ODN cannot be provided

The invention discloses a method, management system and optical time domain reflectometer device for realizing optical path detection and relates to the field of optical communication. The method comprises the steps that the management system determines AWG (Arrayed Waveguide Grating) channel ports OLTx corresponding to to-be-detected branch optical fibers and obtaining OLTx working wavelength information corresponding to the AWG channel ports; the management system confirms the adjusting capability for the OLTx working wavelength information corresponding to the AWG channel ports with the OTDR (Optical Time Domain Reflectometer) device; and under the condition of having the adjusting capability, the management system sends the OLTx working wavelength information corresponding to the AWG channel ports to the OTDR device and informs the OTDR device of carrying out optical path detection on the to-be-detected branch optical fibers at the OLTx working wavelength information corresponding to the AWG channel ports. Under the condition of not adding a hardware module, the optical path detection of a WDM-PON (Wavelength Division Multiplexing-Passive Optical Network) containing an AWG is realized, and the optical path detection when an optical distribution network has no optical line terminal test condition is realized.
Description
technical field [0001] The present invention relates to the field of optical communication, in particular to a method and management system for realizing optical path detection of WDM-PON (Wavelength Division Multiplexing-Passive Optical Network, wavelength division multiplexing passive optical network) containing AWG (ArrayedWaveguide Grating, Arrayed Waveguide Grating) And OTDR (Optical Time Domain Reflectometer, Optical Time Domain Reflectometer) equipment. Background technique [0002] In recent years, the construction of urban optical networks has gradually increased. The deployed PON system is mainly composed of OLT (Optical Line Terminal, Optical Line Terminal) equipment, ONU (Optical Network Unit, Optical Network Node) equipment and ODN (Optical Distribution Network, Optical Distribution Network). Among them, the ODN equipment is mainly composed of a backbone optical fiber, a branch optical fiber, and an optical splitter connecting the two. The optical splitter is ...
