Description

technical field [0001] The invention relates to the field of communication, in particular to an automatic test system and method of a wavelength selection device in the field of communication, which is beneficial to realizing intelligent management and utilization of resources in an optical transmission network. Background technique [0002] In a Dense Optical Wavelength Division (DWDM) network, an Optical Add-Drop Multiplexer (OADM) is often used to increase the flexibility of the system, especially in a metropolitan area network. The original OADM can only realize the add / drop function of a fixed wavelength, and once the network configuration and construction are completed, the network architecture cannot be modified. With the increase of emerging services, the improvement of flexibility requirements for metro WDM, the evolution of metro WDM to grid, and the growth of operators' interest, the demand for reconfigurable optical add-drop multiplexer (ROADM) system Gradually ...

Problems solved by technology

After the current WSS is provided for production, it is still unable to quickly and accurately judge whether the assignment of all channels to any port is normal. It can only rely on manual adjustment of the input wavelength channel, by issuing wavelength assignment commands, and manual observation is required when recording the results. Changing the light detection channel of the spectrometer or multi-wavelength meter, this manual test method has the following defects: 1) the test efficiency is low, it needs a lot of manpower and working hours, and the productivity is poor; 2) it is difficult to guarantee the wavelength of WSS and upper, lower The test coverage of all wavelength assignments and combinations of the drop channels; 3) The test environment is not well maintained, and it is difficult to ensure a fixed test environment for a long time; 4) Frequent plugging and unplugging of the add and drop channels during the test Optical fiber is easy to cause damage to optical fiber enamel
