3.6.2 Check fiber
3.6.3 Splice
1) Before splicing, you should check and confirm whether the fiber surface is clean
and smooth.
2) Through adjust the position of displayer to finish switching foresight and back vision
.
3) If any flaw appears, please take off the fiber and rehandling it. Please refer to the
following picture.
Note: Fiber check is automatically, press splice button, fusion splicer will auto- focus
and checks the fiber whether there is damage or dust particle.

In order to guarantee better splice, an image processing system has been installed
in M INI4R to observe fiber. H owever, under some situation, t he i mage p rocessing
system may not check some splice error. So, to achieve better splice result, we need
to do v isual i nspection via displayer, t hen t he f ollowing described s tandard splice
procedure.
1) Fiber will do opposite direction movement after putting in fusion splicer, after clean
discharging, the fiber will stop to a specific position, and then fusion splicer will check
the cutting angle and end quality. If cutting angle is large than threshold value or the
fiber end face is not smooth, then the buzzer will ring, at the same time, displayer will
show error message to warn operator. After finish checking, fusion splicer will stop
work, the screen will display offset, clearance distance and cutting angle value.
If no error message display, we should check the following fiber end, if similar
situation appear, we should take down the fiber from fusion splicer and prepare again.
Surface flaw on the fiber may lead to a failure splice.
