OPERATION/MAINTENANCE
CLEANING THE OPTIONAL VFL PORT
=
Isopropyl alcohol (91% or better)
IMPORTANT SAFETY NOTE: WHEN INSPECTING AN OPTICAL PORT, NEVER LOOK DIRECTLY OR INDIRECTLY
INTO THE PORT WITHOUT SUFFICIENT EYE PROTECTION. THE OPTICAL PORT MAY BE ENERGIZED WITH
POWERFUL INVISIBLE RADIATION THAT IS HARMFUL TO THE HUMAN EYE.
This cleaning procedure applies to the optional VFL port on the ZOOM 2 optical power meter. For more information about cleaning
the DETECTOR port on the ZOOM 2, see page 23.
Required Accessories:
=
In-adapter fiber optic inspection scope (200x magnification or greater recommended)
=
In-adapter fiber optic cleaning accessories, such as 2.5mm cleaning swabs or 2.5mm HUXCleaner™
Below are procedures for “wet” cleaning and “dry” cleaning. For best results, a combination of these cleaning methods is
recommended.
=
Compressed Air (optional)
INVISIBLE LIGHT IS ESPECIALLY DANGEROUS SINCE THE EYE IS NOT AWARE OF EXPOSURE TO HARMFUL
INVISIBLE ENERGY, AND BECOMES INCREASINGLY DANGEROUS WITH PROLONGED EXPOSURE.
TO AVOID ACCIDENTAL EXPOSURE TO OPTICAL ENERGY, IT IS HIGHLY RECOMMENDED TO POWER OFF
EQUIPMENT BEFORE INSPECTING OPTICAL PORTS.
IT IS ALSO HIGHLY RECOMMENDED TO USE AN LCD-BASED FIBER INSPECTION SCOPE, WHICH CAN INSPECT
OPTICAL PORTS AND FIBER ENDFACES WITHOUT EXPOSING THE EYE TO HARMFUL OPTICAL RADIATION.
Clean out the optical port according to the directions
provided with the swabs.
“WET” CLEAN PROCEDURE
Blow dry the optical port with the compressed air. If
compressed air is not available, allow 2 minutes for
the alcohol to evaporate.
Carefully insert the wet tip of the swab into the optical
port.
Inspect the optical port with the in-adapter fiber optic
inspection scope to ensure the port is clear of
obstructions.
Wet the tip of a 2.5mm cleaning swab with isopropyl
alcohol.
If the port is still dirty, another round of cleaning will be
necessary. You may also want to use a combination of “wet”
and “dry” cleaning to achieve best results.

“DRY” CLEAN PROCEDURE
Carefully insert a dry 2.5mm cleaning swab or a
2.5mm HUXCleaner™ into the optical port.
Clean out the optical port according to the directions
that came with the cleaning accessories.
Inspect the optical port with the in-adapter fiber optic
inspection scope to ensure the port is clear of
obstructions.
