Embodiment Construction
[0017] In the following description, for purposes of illustration rather than limitation, specific details such as specific device structures and techniques are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0018] see figure 1 , figure 1 A schematic structural diagram of a node device in an optical network provided by an embodiment of the present invention. Depend on figure 1 It can be seen that the node device 100 at least includes: a first unit 101, a second unit 102, a management control unit 105, and two storage units; wherein, the first unit 101 is connected to the first storage unit 103, and the first stora...

The present invention provides a method for obtaining optical link relationship, a panel point device and an optical networking system. The method is applied to the internal panel point device. In the panel point device, a first unit is connected with a first storage unit which is connected with a first terminal of the optical; a second unit is connected with a second storage unit which is connected with a second terminal of the optical; and a management control unit is respectively connected with the first unit and the second unit. The method comprises the steps that: the first unit obtains a first port identification information of the optical prestored by the first storage unit and associates the port identification information connecting with the self with the first port identification information; the second unit obtains the second port identification information of the optical prestored by the second storage unit, and associates the port identification information connecting with the self with the second port identification information; the management control unit obtains the associated information and determines the optical link relationship between the first unit and the second unit.
Description
technical field [0001] The invention relates to the technical field of optical communication, in particular to a method and a device for detecting an optical fiber connection relationship. Background technique [0002] With the rapid development of communication networks, optical networks have become the core of future wide area networks and metropolitan area networks. Among them, a wavelength division multiplexing (Wavelength Division Multiplexing, WDM) optical network has received extensive attention. Usually, in a node device in a WDM optical network, some internal units are connected through a large number of optical fibers. The method adopted in the prior art is: modulate a low-frequency signal on the optical wavelength, and the node device can obtain its own internal optical fiber connection relationship according to the detected low-frequency signal. [0003] However, before modulating low-frequency signals, it is necessary to ensure that the laser at the source end...
