Optical Diagnostics and Troubleshooting

Ways to learn:
Instructor-led | Self-study materials | Learning labs

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.
