Title:
METHOD AND SYSTEM FOR ACQUIRING OPTICAL FIBER CODING, AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/031552
Kind Code:
A1
Abstract:
A method and system for acquiring an optical fiber coding, and a related device. The method is applicable in the field of optical access networks. An optical line terminal (OLT) transmits a target instruction to an optical time-domain reflectometer (OTDR), used for instructing the OTDR to transmit an optical signal to all branch optical fibers so that the OTDR receives at least one reflected signal, thus acquiring the at least one reflected signal received by the OTDR; insofar as the at least one reflected signal comprises at least two reflected signals, the OLT acquires at least two reflection peak positions of the at least two reflected signals, and performs recognition on at least one reflection peak position acquired on the basis of the at least two reflection peak positions so as to acquire an optical fiber coding of at least one branch optical fiber, thus implementing the positioning of a branch optical fiber on the basis of a reflection peak position in the spatial dimension. The present solution obviates the intervention of a third-party medium, ensures the reliability of an optical fiber positioning technique; and, implementation is possible by employing one optical signal, the solution is simple and easy to implement.
