Free Practice Questions for Nokia 4A0-265 Exam

The statement that WT uses a unique identifier based on a pair of numbers encoded by Optical Transponders (OTs) into each service wavelength direction is TRUE. WT is a feature of the 1830 PSS that allows for automatic identification and tracking of wavelengths across different network elements and domains. WT uses Wave Keys, which are unique identifiers composed of two numbers: a Wave Key ID and a Wave Key Code. The Wave Key ID identifies the OT that generates the wavelength, while the Wave Key Code identifies the wavelength itself within a given OT6. The Wave Keys are encoded by OTs into each service wavelength direction using phase modulation, and can be decoded by other OTs or amplifiers that have WT capability. WT enables various applications and benefits, such as simplified commissioning, automated wavelength routing, enhanced fault localization, and improved network security. References : Nokia Optical Diagnostics and Troubleshooting Course | Nokia, Optical User Guide - Nokia, Alcatel-Lucent 1830 PSS-8 and PSS-16 Photonic Service Switch

The command show wavekey wtsource power displays a list of the expected and measured output power for the channels whose admin state is up. This command is useful to monitor the power levels of the channels that are encoded with Wave Keys, which are unique identifiers for wavelength tracking. The command output shows the channel number, wavelength, Wave Key ID, Wave Key Code, expected output power, measured output power, and power difference for each channel1. The command can be used on both OTs and amplifiers that support WT capability2. References : Nokia Optical Diagnostics and Troubleshooting Course | Nokia, Optical User Guide - Nokia
