General splicing steps

This section explains the steps involved in automatic splicing process and
describes how various program parameters are related to this process. The normal
splicing process can be divided into two sections; pre-fusion and fusion.

Pre-fusion

During pre-fusion, the splicer performs automatic alignment and focusing, where
the fibers are subjected to a low pre-fuse current for cleaning purposes; a pre-fuse
image is also taken. At this point, the user is informed of any problems recognized
in the pre-fuse image, such as a poorly prepared fiber. The splicer will then issue a
warning before the fibers are fused together.

Fusion

During fusion, the fibers are joined together and subjected to five different
currents as illustrated below. An important parameter, which changes during
splicing, is the distance between the fibers. During pre-fusion, the fibers are apart.
With the current phase changing, fibers are spliced gradually.

Splicing process

Arc power and arc time are considered as the two most important parameters (as
shown in the figure below). The name and purpose of those parameters as well as
the effect and importance of the parameters will be described in the next section
"Splice program parameters under general splicing process". The below figure
shows the arc discharge conditions (relationship between "Arc power" and "Motor
motion"). These conditions can be modified by changing the splicing parameters
listed below. However, depending on the splice mode, certain parameters cannot
be changed.
