The T‑BERD/MTS‑5800 with a 4100‑series DWDM OTDR module uses the Smart Test Assistant to simplify DWDM fiber testing by guiding setup, execution, and results analysis. Before testing, all connectors must be inspected and cleaned with a VIAVI P5000i or FiberChek probe until they pass inspection to ensure accurate measurements. The quick card explains how to connect the tester to the fiber under test, configure DWDM OTDR settings, run automated scans, and interpret results. This workflow improves testing efficiency, speeds troubleshooting, and ensures reliable validation of DWDM channels and fiber conditions.
