3. Arc Calibration
Atmospheric conditions such as temperature, humidity, and pressure are constantly
changing, which creates variability in the arc temperature. This splicer is equipped with
temperature and pressure sensors that are used in a constant feedback monitoring control
system to regulate the arc power at a constant level.
Changes in arc power due to electrode wear and glass adhesion cannot be corrected
automatically. Also, the center position of arc discharge sometimes shifts to the left or
right. In this case, the fiber splicing position has to be shifted in relation to the arc
discharge center. It is necessary to perform an arc power calibration to eliminate both of
these issues.
Operation procedure
(1) Select [Arc Calibration] in [Splice Menu] to display Arc Calibration screen.
(2) Set prepared fibers in the splicer.
(3) The following is performed after pressing .
1. Arc discharge is performed without fibers in the view screen to detect the center
of arc discharge and adjust the gapset position.
2. Fibers are spliced with an intentional axis offset for arc power calibration.
3. Axial offset decreases by the surface tension effect when multiple re-arcs are
performed. During the process, the change of axial offset amount is measured
and this is taken into consideration to calibrate arc power.
• Arc calibration is performed automatically using [AUTO] mode only. So arc
calibration does not have to be performed when splicing in this mode.
• Performing the [Arc Calibration] function changes the arc power “factor”
value. The factor value is used in the algorithm program for all splicing. The
arc power value will not change in the splice modes.
• Use standard SM or DS fiber for arc calibration.
• Use well prepared fibers for arc calibration. Dust on the fiber surface affects
arc calibration.
• Cleave angle threshold does not link to the parameter "Cleave Limit" in
splicing modes. Cleave angle threshold is independently set for arc
calibration. See [Other Option] (Page 56) to change cleave angle threshold.
