What does confirming splitter output levels before connecting outputs achieve when replacing splitters?

Confirming splitter output levels before connecting outputs is an important practice that helps to reinforce technician confidence in resolving the issue. When a technician measures and verifies the output levels, they can ensure that the splitter is functioning correctly and that the signals being routed through it meet the necessary specifications. This assessment provides reassurance that the installation or replacement was successful and that the system should operate as intended.

By taking this step, the technician can identify potential issues such as signal loss or gain discrepancies which could affect the performance of the network. It ultimately supports the technician's understanding of the system performance and leads to informed decisions in troubleshooting or optimizing the network setup.

This practice does not guarantee that the splitter won't fail again, as components can always experience issues after installation. Furthermore, while it is a good practice, it may not necessarily be considered a formal industry standard that must be followed in all cases. It’s more about maintaining high-quality service and reliability in network performance.
