Abstract
A method, device and system for detecting optical signal are provided. The method includes that: an optical signal receiving node receives, from an optical signal sending node, an optical channel signal and the in-band overhead information of the optical channel signal; the optical signal receiving node carries out a misconnection detection on the optical channel signal according to the in-band overhead information and generates corresponding alarm information after determining that there is a misconnection, wherein an OCh TTI and Optical channel signal normal central frequency are carried in the in-band overhead information. The disclosure addresses the problem of how to effectively detect the misconnection of optical fibers after coherent reception technologies, including flexible grid, inverse multiplexing and optical devices, are introduced into related technologies and improves the optical signal receiving accuracy and the error detection and correction capability of a system.
