SmartClass Fiber OLP-82/-85 Optical Power Meters
Measuring Absolute Power
This quick card describes how to use VIAVI SmartClass Fiber OLP-82 and OLP-85 series Optical Power
Meters (OPMs) to measure absolute power (dBm).
Equipment Requirements:
• SmartClass OLP-8x Optical Power Meter:
o OLP-82 Optical Power Meter
o OLP-82P Optical Power Meter w/ Patch Cord Microscope
o OLP-85 Optical Power Meter
o OLP-85P Optical Power Meter w/ Patch Cord Microscope
• Fiber optic cleaning and inspection tools
• Fiber optic patch cord (Reference Cable)
• Optical Coupler to connect Reference Cable to
Fiber Under Test (FUT)
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 of signal(s) to measure
Connect to Fiber Under Test (FUT):
The OLP-8x may be connected to the FUT via an optical patch panel or an optical coupler as follows.
All fibers and connectors should be inspected and cleaned prior to connection:
1. Inspect and, if necessary, clean fiber end face of the Reference Cable.
2. Connect the Reference Cable to the Power Meter port, under the flap on top of the OLP.
3. If the interface to the Fiber under Test is a patch cord, connect the patch cord to an optical coupler
with the same connector type.
4. Inspect and, if necessary, clean the FUT connected to the coupler or patch panel.
5. Inspect and, if necessary, clean the other fiber end face of the Reference Cable.
6. Connect the Reference Cable to the coupler or patch panel leading to the light source.
