T-BERD /MTS-2000 Modular Test Set
E4100 OTDR Module Optical Light Source option
This procedure describes how to use an E4100-series OTDR module as an Optical Light Source (OLS).
If optioned, the OTDR module can operate as an OLS or Optical Power Meter, but not both at the same
time. Note: the E41PM built-in power meter can be used at the same time as the Light Source options.

Equipment Requirements:

• T-BERD/MTS-2000 equipped with the
following:
o Fiber Optics Software Release V17.30
or greater
o E4100 Series OTDR Module
o E41OTDRLS Light Source option
• Fiber optic cleaning and inspection tools
• Launch Cable (patch cord) 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 Fiber (Multimode or Single Mode)
• Type of Connectors (SC UPC, SC APC, LC UPC, etc.)
• Wavelength(s) to be tested (850nm, 1300nm, 1310nm, 1550nm, etc.)

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 connectors,
patch cords, 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.
