Basic Operation
Splice loss increase: Cause and remedy
Symptom
Cause
Remedy
Axial offset
Dust on v-groove or
fiber clamp chip
Clean v-groove and fiber clamp chip.
Fiber angle
Dust on v-groove or
fiber clamp chip
Clean v-groove and fiber clamp chip.
Bad fiber end-face
quality
Check if fiber cleaver is well conditioned.
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 if fiber cleaver is well conditioned.
Prefuse power too low
or prefuse time too
short.
Increase [Prefuse Power] and/or [Prefuse Time].
Separation
Fiber stuffing too
small
Perform [Motor Calibration]
Prefuse power too
high or prefuse time
too long.
Decrease [Prefuse Power] and/or [Prefuse
Time].
Fat
Fiber stuffing too
much
Decrease [Overlap] and perform [Motor
Calibration].
Thin
Arc power not
adequate
Perform [Arc Calibration].
Some arc parameters
not adequate
Adjust [Prefuse Power], [Prefuse Time] or
[Overlap].
Line
Some arc parameters
not adequate
Adjust [Prefuse Power], [Prefuse Time] or
[Overlap].
A vertical line sometimes appears at the splice point when MM fibers or
dissimilar fibers (different diameters) are spliced. This does not affect splice
quality, such as splice loss or tensile strength.
