Nokia Optical Diagnostics
and Troubleshooting

Course number: TOP00007
Course duration: 4 days
Price: €3,200

Course overview

This course provides students with the knowledge and hands-on skills required to troubleshoot and resolve Nokia photonic nodes' issues using direct web and command line interfaces. Participants will learn optical signal flow through a node using the Nokia 1830 Engineering and Planning Tool (EPT) reports for consistency analysis, retrieving optical power data and current alarms/conditions, troubleshooting and repairing a transmission, and system/optical transponder faults. The course includes extensive hands-on lab exercises to ensure students acquire practical skills on the topics presented.

Recommended prerequisites

Nokia Optical Networking Fundamentals

Alternatively, familiarity with the following topics:

Optical transmission concepts (e.g., optical fiber types, WDM functional blocks, etc.), equipment and protection schemes
Familiarity with standard optical node architectures (e.g., FOADM, ROADM, CDC-F)
