4.4 Parameters for Normal Splicing Process
parameter
description
Template
A list of splice modes stored in the splicer database is displayed.
Upon inputting the appropriate mode, the selected splice mode
stored in database area is copied to a selected splice mode in user-
programmable area.
Name
Title for a splice mode expressed in up to seven characters.
Note
Detailed explanation for a splice mode expressed in up to 15
characters. It is displayed at “Select splice mode” menu.
Arc adjust
Set to adjust arc power according to the fibers’ conditions.
Pull test
If “Proof test” is set to “ON”, a pull-test is performed upon opening
the windproof cover or by pressing the SET button after splicing.
Loss
estimate
Loss estimate should be regarded as a reference. Since the loss is
calculated upon the fiber image, there is certain difference with the
real value. The estimate method is based on a single mode fiber and
calculates at the wavelength of 1.31μm. The estimated value can be a
valuable reference, but cannot be used as the basis of acceptance.
Minimum
loss
This amount is added to the estimate splice loss originally calculated.
When splicing specially 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 actual splice
loss to minimum value (minimum loss).
Core angle
limit
An error message is displayed if the bend angle of the two fibers
spliced exceeds the selected threshold (Core angle limit).
Cleave angle
limit
An error message is displayed if the cleave angle of either the left or
right fiber ends exceed the selected threshold (cleave limit).
Gap
Set the end-face gap between the left and right fibers at the time of
aligning and pre-fusion discharge.
Overlape
Set the overlap amount of fibers at the fiber propelling stage.
Relatively small [Overlap] is recommended if [Preheat Arc Value] is
low, while relatively large [Overlap] is recommended if [Preheat Arc
Value] is high.
Cleaning Arc
time
A cleaning arc burns out micro dust on the surface of the fiber with
an arc discharge for a short period of time. The duration of the
cleaning arc can be changed by this parameter.
