    摘要： 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 present invention 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.

    摘要： A data mapping method and a data mapping device for an optical transport network are provided. The method includes: mapping packet service data or constant bit rate data to a Super Optical Channel Data Unit (ODUS) and mapping the ODUS to a Super Optical Channel Transport Unit (OTUS); distributing the OTUS to a plurality of electrical lane signals, dividing the plurality of electrical lane signals into one or more groups and mapping the one or more groups of electrical lane signals to corresponding Super Optical Channels (OChSi), wherein rates of the ODUS and the OTUS are both N times of 100Gb/s, a rate of the OChSi is M times of 100Gb/s, tributary slot sizes of the ODUS and the OTUS are both 100Gb/s, where N is a positive integer equal to or greater than 2, i is a positive integer, and M is a positive integer equal to or greater than 1 but less than N. The present invention enables an operator to deploy a beyond-100G optical transmission system more flexibly, without being limited to select a fixed rate, and improves the spectrum utilization rate of fiber as well as the flexibility and the compatibility of a system.

    摘要： Disclosed are a method and device for managing optical channel overhead, and an optical signal receiving node. The method comprises: optical channel overhead information is structured, wherein the optical channel overhead information comprises at least one of the following: the optical channel nominal central frequency, the optical channel application code, and the optical channel trail trace identifier; and the optical channel overhead information is sent to the optical signal receiving node. The present disclosure solves the technical problem in the related art of an inability to negotiate a single, unified optical channel nominal central frequency and application code between the optical transmitter and the optical receiver, i.e. the present disclosure enables an optical transmitter and the optical receiver to negotiate such the nominal central frequency and application code, thereby achieving the technical result of an optical signal being correctly sent and received.

    摘要： A method and device for mapping data in an optical transport network are provided. The method includes: packet service data is mapped to a Super Optical Channel Data Unit (ODUS) and the ODUS is mapped to a Super Optical Channel Transport Unit (OTUS); and the OTUS is mapped to a Super Optical Channel (OChS), wherein rates of the ODUS, the OTUS and the OChS are all N times of 100Gbit/s, a tributary slot size of the ODUS is100Gbit/s, and N is a positive integer equal to or greater than 2. The present invention enables an operator to deploy a beyond-100G optical transmission system more flexibly without being limited to select a fixed rate, improving the spectrum utilization rate of fiber as well as the flexibility and the compatibility of the system.
