OneAdvisor-800 Modular Test Set
Measuring Optical Power Levels with a 4100-series OTDR Module
This procedure describes how to use an E4100-series OTDR module as an Optical Power Meter (OPM).
If optioned, the OTDR module can operate as an OPM or Optical Light Source, but not at the same
time. Light Source is a standard feature on most new OTDR modules, while Power Meter is an option.

Equipment Requirements:

• OneAdvisor-800 equipped with the
following:
o Fiber Optics Software Release V19.92
or greater
o E4100 Series OTDR Module
o E41OTDRPM Power Meter option
• Fiber optic cleaning and inspection tools
• Reference Cable (patch cord) with
connectors matching the OTDR port and
Fiber Under Test
• Optical Coupler to connect Reference
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,
Reference Cable, bulkhead connectors,
patch cords, etc.)
• Focus the fiber on the screen. If dirty,
clean the end-face.
• If it appears clean, run inspection test.
• If it fails, clean the fiber and re-run
inspection test. Repeat until it passes.
