T-BERD /MTS-5800 Modular Test Set
CWDM OTDR Smart Test Assistant
This quick card describes how to connect to a fiber under test and use the Smart Test Assistant to
configure test setups, run tests, and analyze results on a VIAVI T-BERD/MTS-5800 equipped with a
4100-series CWDM OTDR module.
The CWDM OTDR is meant to test a specific wavelength on a live Coarse Wavelength Division
Multiplexed (CWDM) network. Care must be taken to select and test the correct wavelength.
Equipment Requirements:
• T-BERD/MTS-5800 equipped Software
Release V18.0 or greater
• E4100 Series CWDM OTDR Module
(E41CWDMC10L, E41CWDM10U, or
E41CWDM8U)
• Fiber optic cleaning and inspection tools
• Launch Cable (minimum 20-meter Fiber optic
patch cable) with connectors matching the
OTDR port and Fiber Under Test
• Optical Coupler to connect Launch Cable to
fiber under test
The following information is required to
complete the test:
• Type of Connectors (SC UPC, SC APC, LC, etc.)
• Distance unit (feet, meters, miles, kilometers)
• CWDM Wavelength to be tested
Fiber Inspection Guidelines:
• Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every
connection being used (OTDR Port, Launch
Cable, bulkhead connector, patch cables, etc.)
• Focus the fiber on the screen. If dirty, clean
the connector.
• If it appears clean, run inspection test.
• If it fails, clean the fiber and re-run inspection
test. Repeat until it passes.
