Attend the Nokia Optical Diagnostics and Troubleshooting course or purchase the course materials.

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)

After completing the course, students should be able to leverage Nokia resources for product documentation, describe the optical signal flow through an 1830 PSS node, explain different amplifier configurations, understand Raman amplification with Erbium Doped Fiber Amplification, locate configured span information and commissioning data, describe active alarms and conditions, retrieve and export alarms, conditions, and logs, recognize Performance Monitoring measurements (PMs), configure loopbacks, and configure power management settings for troubleshooting.

This document covers various topics related to power-related alarms and messages, manual power adjustments, troubleshooting power adjustment failures, tracing a service along an optical path, performing channel power monitoring, detecting wavelength tracker detection points, identifying wave key sources, detecting unexpected or missing channels, determining alarms in a fiber cut situation, detecting unidirectional and bidirectional fiber cuts, describing the OTDR card, calculating span loss, identifying optical supervisory channel information and alarms, troubleshooting common OSC issues, resolving transponder configuration issues, resolving FEC configuration issues, resolving payload type and encapsulation mode issues, and resolving fiber connection issues through the Trail Trace Identifier (TTI).
