Hi there!
This post is about the error code of the NG WDM network. Please have a look below.
BACKGROUND INFORMATION
NG WDM system line optical power, system dispersion value, single-wave optical power, transmission equipment components and other issues can introduce business errors. Therefore, the analysis of BER errors in wavelength division systems requires analysis of system indicators in many aspects, and comprehensive analysis of various phenomena. Positioning. The key to analyzing the error problem is to find out the source of the error introduction, in order to effectively locate the fault point.
HANDLING SUGGESTIONS
1. The key to error processing is to find out the source of the error. Therefore, it is necessary to eliminate the external fault of the system, that is, to ensure that the input service on the customer side is normal.
2. Error processing suggestion from multi-wave to single-wave, that is, multi-wave simultaneous error of the common channel, focusing on analyzing common channels of multiple wavelengths.
3. When there is a bit error in the service layer service, there is usually a bit error in the sub-layer service. For example, when there is an error in the ODUk SM segment, there is usually an ODUk PM segment error, and vice versa is not necessarily established. Therefore, when the error is processed, press SM/PM sequential processing, processing segment errors first, and then processing channel errors.
4. Wavelength division equipment switching will cause service interruption, so there may be several error counts at the receiving end. Therefore, it is necessary to eliminate business interruption caused by business switching.
5. Automatic adjustment of system optical power or optical power, dispersion, etc. of the device may also cause sporadic errors.
6. Observe whether the associated board service is normal. You can determine whether the fault is on the cross-board or by creating a broadcast cross-assisted fault analysis.
7. When the crossover and clock board failure are suspected, cross-board switching can be performed to confirm that the backplane connector is in good contact and the backplane bus state.
8. Under normal adjustment of the crossover and clock board, you can try to replace the operation of the service board to check whether the fault is related to the slot.
9. Replace the faulty board to determine whether the board is faulty.
This would be all on the error code of the NG WDM network. Thanks for reading this post!
