Below is a figure showing the Arc discharge conditions (relationship between
"Arc power" and "Motor motion"). The conditions can be edited by changing
the splicing parameters listed below. Depending on splice mode, certain
parameters cannot be changed.
Select Splice Mode
AUTO splice mode
In AUTO mode, the amount of heat applied to the fiber is calibrated in real time by
analyzing the cladding illumination during arc discharge and adjusting the arc
current accordingly. This splice mode does not require the operator to perform an
arc calibration.
This mode identifies the type of fiber and selects optimized splice condition
automatically and splice.
If the fiber type is identified, you can work splicing with stability by selecting AUTO
mode for each fiber type.

Splice mode
Description
AUTO
SM/NZ/DS/BIF/
MM
This splice mode can splice standard telecommunications grade
fiber, including SMF (ITU-T G652), NZDSF (ITU-T G655), DSF
(ITU-T G653), BIF (ITU-T G657) and MMF (ITU-T G651).
This mode uses the standard parameters. Therefore, the splice
loss may be higher than another Auto mode. If the fiber type is
identified, uses the specific Auto mode.
SM AUTO
This splice mode can splice standard SM fiber.
MFD: 9 to 10µm, Wavelength: 1310nm, ITU-T G.652
MM AUTO
This splice mode can splice the standard MM fiber.
Core diameter: 50.0µm, 62.5 µm, ITU-T G.651
NZ AUTO
This splice mode can splice the standard NZDS fiber.
MFD: 8 to 10 µm, Wavelength: 1550nm, ITU-T G.655
DS AUTO
This splice mode can splice the standard DS fiber
MFD: 7 to 9 µm, Wavelength: 1550nm, ITU-T G.653

Points to note: AUTO SM/NZ/DS/BIF/MM mode
NZDS is specified using the splicing mode for standard NZDS fiber.
However, for best results, it is recommended that the optimum splice
mode be selected for a specific type of NZDS fiber. This is due to the
variation in the NZDS fiber properties and optimum splicing parameters
are different from one type of NZDS fiber to the next.
