The T‑BERD/MTS‑5800 with the OCC‑4056C module provides fast DWDM channel verification by measuring channel presence and power levels. Before testing, all connectors must be inspected and cleaned using a VIAVI P5000i or FiberChek probe until they pass inspection. The quick card explains how to connect the tester to the fiber under test, configure DWDM Optical Channel Checker settings, run measurements, and analyze results. This workflow helps technicians quickly identify wavelength or power issues, ensuring accurate DWDM channel validation and efficient troubleshooting in high‑density optical networks.
