There’s dust in V-grooves and fiber
hammer
Clean the V-grooves and fiber hammer
Bad fiber end-face quality
Check the cleaver
Fiber core bend-
ing
Bad fiber end-face quality
Check the cleaver
Pre-fuse power too low or pre-fuse
time too short.
Increase [Pre-fuse Power] and/or[Pre-fuse
Time].
The mode field
diameters mis-
match
Arc power not adequate
Increase [Pre-fuse Power] and/or[Pre-fuse
Time].
Dust combustion
Bad fiber end-face quality
Check the cleaver
Dust still present after cleaning fiber
or cleaning arc.
Clean fiber thoroughly or
increase[Cleaning Arc Time]
Bubbles
Bad fiber end-face quality
Check the cleaver
Pre-fuse power too low or pre-fuse
time too short.
Increase [Pre-fuse Power] and/or[Pre-fuse
Time].
Separation
Fiber stuffing too small
Perform [Arc Calibration].
Pre-fuse power too high or pre-fuse
time too long.
Decrease [Pre-fuse Power] and/or [Pre-fuse
Time].
Fat
Fiber stuffing too much
Decrease [Overlap] and Perform [Arc Calibra-
tion].
Thin
Arc power not adequate
Perform [Arc Calibration].
Some arc parameters not adequate
Adjust [Pre-fuse Power], [Pre-fuse Time] or
[Overlap]
Splicing line
Some arc parameters not adequate
Adjust [Pre-fuse Power], [Pre-fuse Time] or
[Overlap]
⚠ Note:
When different optical fibers (different diameters) or multi-mode fibers splicing, they will produce a vertical line which we
call the "splicing lines" in a subsequent point, this does not affect splicing quality (splicing loss and splicing strength).
