Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a method and an apparatus for determining a path of a wavelength division device. Background technique [0002] With the development of optical communication technology, wavelength division multiplexing equipment (referred to as "wavelength division equipment") has been more and more widely used. A WDM device is generally composed of multiple boards that implement different functions. The ports of each board inside the device are connected through the optical fiber in the network element or the electrical crossover on the backplane. The ports of the boards between different devices The networks are connected through optical fibers between NEs. The WDM equipment path refers to a series of WDM boards and optical fiber connections between boards or a combination of backplane crossovers formed to complete a certain service transmission. WDM trail...

AI Technical Summary

Problems solved by technology

The existing methods for determining the path of WDM equipment are mainly aimed at old OTM WDM equipment, because OTM (Optical Terminal Multiplexer, Optical Terminal Multiplexer) WDM equipment does not have the method of collecting signal flow direction or internal fiber connection , resulting in the routing relationship basically relying on manual maintenance, complicated and error-prone

Therefore, when the communication service opening involves optical channel scheduling, it is generally impossible to carry out refined management and quality monitoring due to unclear pathfinding of the internal routing of the optical channel.
