Details of each parameter are shown below.
Parameter Explanation
ARCPER This parameter determines discharge current by bit unit. The possible
range is 0 – 31 bit. The discharge current is approximately
10.0+0.3*DATA(mA).
ARCTIME Arc discharge time
FORWARD Movement time of the left fiber during Arc discharge. If fiber stuff amount
is not suitable, adjust this parameter.
PREFUSE Heating time before stuffing. The fiber end surfaces must be slightly
melted by preheating before stuffing. It is not needed to change this
parameter usually. But if bubble often happens after splicing, changing
PREFUSE may efficient.
GAP The distance between both fiber ends just before the arc discharge. “Line”
is the unit of the “GAP” value. One line is approximately 2um. It is not
needed to change this parameter usually.
ECF “ECF” is the acronym for Eccentricity Current Factor. It is not needed to
change this parameter usually.
ANGLE The rotational angle after θ axis alignment of the PM fiber. Unit is degree.
The left fiber rotates by this amount after θ axis alignment.
PMALIN Method for aligning PM fiber in P3 mode. It determines θ axis alignment
is performed by MAX method or MIN method.
In the case of MIN aligning,
θ axis alignment is done so that power meter
reading should be minimum. It means the polarization axis of the
polarizer and the analyzer are set 90 degrees difference. MIN method
enables high precision aligning when measurement system has large
dynamic range.
In the case of MAX aligning,
θ
axis alignment is done so that power meter
reading should be maximum. It means the polarization axis of the
polarizer and the analyzer are matched. MAX method is effective when
measurement system doesn’t have large dynamic range.
[NOTE] The discharge current is automatically compensated for atmospheric
pressure.
