Activating a fiber-optic network involves several critical steps, and one of those is adjusting attenuation levels. This adjustment takes place during the equipment activation stage. In this phase, the individual components of the network, such as the fiber-optic cables and associated equipment, are powered and tested to ensure they function correctly and meet the required specifications.

During equipment activation, technicians have the opportunity to monitor the signals and make necessary adjustments to the attenuation levels, ensuring that the signal strength is optimized for the network’s operational requirements. This step is crucial as it establishes the foundation for a reliable and efficient data transmission system.

The other stages, while important in the overall process of network activation, do not specifically focus on the adjustment of attenuation levels for the first time. Initial setup typically involves the physical configuration and connection of equipment but not the fine-tuning of system performance. Final quality assurance occurs after all testing has been completed and the system is confirmed to operate as expected, while preliminary testing focuses on verifying basic functionality before moving on to more detailed assessments. Thus, the correct answer highlights the specific moment when critical adjustments to attenuation are first made within the network activation process.
