Maintenance of Splicing Quality
1. Cleaning and Checking before Splicing
Critical cleaning points and maintenance checks are described below.
1-1. Cleaning V-grooves
If contaminants are present in the V-grooves, proper clamping may not occur, resulting
in higher splice loss. The V-grooves should be frequently inspected and periodically
cleaned during normal operation. To clean the V-grooves, do the following:
(1) Open the wind protector.
(2) Clean the bottom of the V-groove
with an alcohol-impregnated thin
cotton swab. Remove excess
alcohol from the V-groove with a
clean dry swab.
(3) If the contaminants in the V-groove
cannot be removed with an
alcohol-impregnated thin cotton
swab, use a cleaved fiber end-face
to dislodge contaminants from the
bottom of the V-groove. Repeat
step (2) after this procedure.
•Be careful to not contact the
electrode tips.
•Do not use excessive force
when cleaning the V-groove.
The V-groove arm may get
damaged.
