Title:
PORT IDENTIFICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/088839
Kind Code:
A1
Abstract:
The present application provides a port identification method and apparatus, belonging to the field of optical fiber communication technology. Said method is applied to a passive optical network (PON). The PON comprises at least one stage of splitters and at least one optical network terminal (ONT), and the wavelengths of test light reflected by reflection components of different ports of the same splitter are different. Said method comprises: acquiring reflection information of respective reflection peaks formed by the reflection of respective test light, provided by a wavelength-adjustable device, by each ONT when the respective test light is transmitted in a PON; according to the reflection information of the respective reflection peaks, determining a port of a splitter corresponding to each reflection peak group, each reflection peak group comprising reflection peaks of the reflection of the respective test light by the same ONT; and according to first transmission information of at least one reflection peak in each reflection peak group, the port of the splitter corresponding to each reflection peak group, and second transmission information between each ONT and an OLT, determining the corresponding port of each ONT in the splitter. With the present application, the efficiency of port identification can be improved.
