Parameter
Description
Prefuse and Stuff
Prefuse
Power
Sets the power of the prefuse arc, which is an arc discharge
occurring from the beginning until the fibers begin stuffing.
If [Prefuse Power] is set too low, axial offset may occur if
cleaved angles are relatively poor. If [Prefuse Power] is set
too high, fiber end faces are fused excessively and splice
loss gets worse.
Prefuse
Time
Sets the duration of the prefuse arc, which is arc discharge
occurring from the beginning until the fibers begin stuffing.
Longer [Prefuse Time] is synonymous with higher [Prefuse
Power].
Overlap
Sets the overlap amount of fibers at the fiber stuffing stage.
Relatively small [Overlap] is recommended if the [Prefuse
Power] is low, while relatively large [Overlap] is
recommended if the [Prefuse Power] is high.
Arc
Arc1 Power
Arc discharge can be separated into two stages. Arc1
Power is the first stage. This sets Arc1 Power.
Arc1 Time
Sets Arc1 time.
Caution If Arc1Time is set 1 sec. or less and Arc2 Power
is set to "OFF", the splice may break during proof-
test stage.
Arc2 Power
Arc2 is the second arc discharge stage. This sets Arc2
Power.
Arc2 Time
Sets the total Arc2 time. Usually set this value to “0sec”.
It is possible to set a very long arc time. However, when
the total of the Arc 1 time and Arc2 time exceeds 30
seconds, always adjust the function [Arc2 ON Time] and
[Arc2 OFF Time] to weaken the arc power. A continuous
arc over 30 seconds, without weakening the arc power, may
damage the arc discharge unit.
Arc2 On-
Time
During Arc2 discharge, arc power can be pulsed by turning
the arc on and off. This sets the amount of time that Arc2
is ON.
Arc2 Off-
Time
Sets Arc2 OFF Time during Arc2. When the Arc2
discharge is intermittent, re-arc discharge is also
intermittent. When continuous re-arc discharge is
necessary, set this parameter to “OFF”.

Parameter
Description
Tapering
Taper Splice
Splice loss is sometimes improved when the fiber is tapered
(pulled) during arc discharge to make the splice thinner.
This sets taper function "ON". The following three
parameters determine the taper shape.
Taper Wait
Sets the taper wait time from the end of fiber stuffing until the
start of pulling fiber.
Taper Speed
Sets the fiber pulling speed.
Taper Length
Sets the fiber pulling length.
Estimation
Estimating
Mode
Selects splice loss estimation to "OFF" ”Clad” ”Core” ”Core-
Fine”
MFD-Left
MFD-Right
Sets MFD of the fibers. This MFD value is taken into
account for estimating splice loss.
Minimum Loss
This amount is added to the estimated splice loss originally
calculated. When splicing specialty or dissimilar fibers, a
high actual splice loss may occur even with optimized arc
conditions. To make the actual splice loss concur with the
estimated splice loss, set the minimum value of estimate to
the minimum optimized actual splice loss.
Wave Length
Sets the wave length. This value is taken into account for
estimating splice loss.
Core Bending
Coef.
Determines how Core bending ( core step / core curve )
influences splice loss estimation. If “Estimating Mode” is set
“OFF” or “CLAD,” Core bending is automatically set “OFF.”
MFD Mismatch
Coef.
Determines how MFD mismatch influences splice loss
estimation. If “Estimating Mode” is set “OFF” or “CLAD,” MFD
mismatch is automatically set “OFF.”
