Maintenance of Splicing Quality

Periodical Checking and Cleaning
In order to maintain the splicing quality of the splicer, periodical inspection and cleaning
are recommended.

Cleaning Objective Lenses
If the objective lens’s surface becomes dirty, normal observation of the core position
may be incorrect, resulting in higher splice loss or poor splicer operation. Therefore,
clean both of them at regular intervals. Otherwise, dirt may accumulate and become
impossible to remove.
To clean the objective lenses, do the following:
(1) Before cleaning the objective lenses, always turn off the splicer.
(2) Gently clean the lenses’ (X-axis and Y-axis) surface with an alcohol-impregnated
thin cotton swab. Using the cotton swab, start at the center of the lens and move the
swab in a circular motion until you spiral out to the edge of the lens surface.
Remove excess alcohol from the mirror surface with a clean dry swab.
(3) The lens surface should be clean and free of streaks or smudges.
(4) Turn on the power and make sure no smudges or streaks are visible on the monitor
screen. Press X/Y key to change the screen and check the state of the lens surface
on both the X- and Y-screens. Perform dust check.
• Fujikura recommends to clean the objective lens when replace the electrode.
• Remove electrode before cleaning objective lens.
• Do not hit or touch tip of electrode when cleaning it.
