Why might a technician who is troubleshooting an outage in an optical network want to refer to the network's as-built documentation?

Referring to the network's as-built documentation is crucial for a technician troubleshooting an outage in an optical network because this documentation provides comprehensive details about the installed system. By reviewing the as-built documentation, the technician can determine specific cable lengths, which is essential for understanding the physical layout and structure of the network. Accurate knowledge of cable lengths aids in identifying potential issues such as fiber breaks or losses that may occur over longer runs or in particular sections of the network.

Additionally, knowing the exact lengths allows the technician to plan for repairs or replacements effectively, ensuring that the right amount of materials is available and suitable for the task at hand. This detailed understanding can expedite troubleshooting, ultimately aiding in restoring the service more efficiently.
