Problems solved by technology
[0006] After careful analysis and research, the inventor found that the above method can realize the automatic discovery of optical fiber connections, but this method has strict requirements for maintenance operators, that is, it is required to insert optical fiber jumpers in order to find the connection between the optical ports. However, in actual operation, the operation and maintenance personnel often perform unified operations on all the optical ports of a single board. If the optical ports are operated according to the connection relationship, there will be great differences with the existing operating habits.
Moreover, when the optical fiber connection relationship between optical ports has both one-to-one and one-to-many situations, the control unit or network management unit must constantly switch working modes, otherwise misjudgment may occur
Therefore, this method has the problem of inconvenient operation for both the maintenance operator and the control unit or network management unit of the optical network node, and it is difficult to apply in practice

The invention provides methods for determining connection relationship between light ports, and one method comprises the following steps: on every light outlet through which an optical wavelength signal or an optical multiplexing section signal passes, the optical wavelength signal or the optical multiplexing section signal is loaded with marks, and the loaded marks are detected; according to theresult of the detection for the marks, the connection relationship between a light inlet and the light outlet is determined. The invention also provides a device for determining the connection relationship between the light ports. The technical schemes are completely technically feasible and have no special requirements for maintenance and operating personnel; therefore, the technical schemes canbe completely used for determining the connection relationship between the light ports and are full practical.
Description
technical field [0001] The invention relates to the optical network technology, in particular to the determination technology of the connection relationship between the optical ports. Background technique [0002] The progress of optical devices has greatly promoted the development of optical communication technology, especially the progress of erbium-doped fiber amplifier (EDFA, Erbium-Doped Fiber Amplifier) and optical multiplexing technology, which has promoted the development of wavelength division multiplexing (WDM, Wavelength Division Multiplex) Large-scale application of equipment. At present, the industry can already provide a Dense Wavelength Division Multiplex (DWDM, Dense Wavelength Division Multiplex) system in which a single optical fiber transmits signals of up to 320 wavelengths. [0003] A WDM device is composed of many functional units with different functions. For example, a WDM device may include a wavelength-level optical signal processing unit. The wav...
