The ONA‑800 with a 4100‑series OTDR module uses the Smart Test Assistant to simplify fiber testing by guiding users through setup, execution, and analysis. After cleaning and inspecting all connectors, technicians connect the launch cable and the fiber under test using an optical coupler. The quick card explains how to configure Smart Test OTDR settings, run automated measurements, and interpret results. With support for multimode or single‑mode fiber, the system ensures accurate link characterization, reduces setup errors, and streamlines testing for efficient troubleshooting and certification.
