4.3 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-
fusion current for cleaning purposes; a pre-fusion image is also taken. At this point, the user is informed of any problems
recognized in the pre-fusion 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.
