Nokia Optical Diagnostics and Troubleshooting

Course Overview

This course provides students with the skills and knowledge required to troubleshoot and resolve problems on the Nokia 1830 PSS-16/32, using direct web and command line interfaces. Topics include: optical signal flow through a node; using the Nokia 1830 Engineering and Planning Tool (EPT) reports for fault analysis; retrieving optical power data and current alarms/conditions; troubleshooting and repair of transmission, system and optical transponder faults. The course includes extensive hands-on lab exercises to ensure students acquire practical skills on the topics presented.
