What kind of testing is performed before installing fiber optic networks?

Before installing fiber optic networks, it is essential to conduct a comprehensive series of tests to ensure that the installation will be successful and reliable. A visual inspection is the first step, where the fiber components, connectors, and the overall installation environment are examined for any visible defects or issues that could affect performance. This includes checking for proper handling and ensuring that no physical damage has occurred to the fibers.

Continuity testing follows the visual inspection and is crucial in verifying that there are no breaks or faults in the fiber optic cables. This test confirms that a signal can successfully pass through the fiber, indicating that the fibers are intact and correctly terminated. By performing these preliminary tests, installers can identify any potential problems early on, leading to a more efficient installation process and minimizing the risk of future network failures.

The other options focus on specific aspects of network operation or performance that generally occur after installation is complete. While optical loss testing is important, it is part of a wider array of checks that are necessary before proceeding with installation. Functional testing of network devices and network performance benchmarking are critical phases but would typically take place after the installation is finalized. Thus, the series of tests including visual inspection and continuity testing are foundational steps that ensure the integrity and readiness of the fiber optic cab
