This value w ill estimate the minimum splice loss, w hen special o r different f ibers
splice will generate high splice loss, even it is in best splice discharging condition. In
order to make actual splice loss access to the minimum splice loss, we must set the
minimum estimated value according to the optimal actual splice loss.

description
LCD
Splice mode chart is stored in the data base of fusion splicer, according to the proper
input splice mode to store in the data base, the selected splice mode will copy to user
programmable zone.
parameter
Name
Subjects of splice mode, seven characters at most.
Note
Detailed expound of splice mode, fifteen characters at most will display on select
splice mode option.
Discharging
adjustment According to the fiber to adjust the arc power.
Overlap volume
Strain relief test If set Strain relief test to ON, when open the wind-proof after finish splicing will
complete strain relief test, or click SET key.
Loss evaluation
Loss evaluation should be viewed as the evaluation of continuous loss value.
According
to the fiber image to calculate the continuous loss will be deviation with the true value.
The arithmetic of estimation loss based on monomode optical fiber; take 1.31um
transmission wavelength to advance. This estimated value possesses preferable
reference value when in good splice condition, but it can’t be viewed as the evidenc
e
of project acceptance.
Minimum loss
Set prefusing discharging power, this is the discharging current strength when begin
discharging to propel the fiber time. If the “prefusing discharging current strength” is
too low while t he cut a ngle is relative b ad, then axial o ffset w ill o ccurred. I f the
“prefusing d ischarging current s trength” i s too high, t hen f iber e nd f ace w ill m elt
excessively, and the splice loss will increased.
Prefusing discharging
current strength
Distance
Set the end spacing distance of alignment fibers and prefusing discharging.
Fiber core offset
limiting value
If the curvature of two fibers beyond the threshold values it will display error message.
Splice discharging
current strength
Set electric arc discharging current strength.
Splice discharging time Set electric arc discharging time.
Clean discharging time
Set the overlap volume in fiber propel stage, if the “prefusing discharging curre nt
strength” is low, we recommend “relative lower overlap volume”, if the “prefusing
discharging current strength” is relative larger
, we recommend “relative larger overlap
value”.
Clean discharging can burn the tiny dust on fiber surface in very short dischargi ng
circle, so discharging time can make parameter changes through this .
Preheat discharge time
Set prefusing discharging circle, this is the length when begin discharge to propel fiber
time. “Preheat discharge time” is high synchronous with “prefusing dischargi ng
current strength”
Cutting angle
limiting value
If the fiber end cutting angle of the left and right fiber or either of each beyond the
selective value will display error message
