A list of splice modes stored in the splicer database is displayed. Upon inputting the appro-
priate mode, the selected splice mode stored in database area is copied to a selected splice
mode in user-programmable area.
Title for a splice mode expressed in up to seven characters.
Detailed explanation for a splice mode expressed in up to 15 characters. It is displayed at
"Select splice mode" menu.
Set the aligning type for the fibers.
"Core" : fiber core alignment
Sets to adjust arc power according to the fibers' conditions.
If "Pull 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 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.
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).
An error message is displayed if the estimated splice loss exceeds the selected threshold (loss
limit).
An error message is displayed if the bend angle of the two fibers spliced exceeds the selected
threshold (Core 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).
Set the relative position of the splicing location to the center of electrodes. Splice loss may
be improved in the case of dissimilar fiber splicing by shifting [Gap position] towards a fiber
whose MFD is bigger than the other fiber MFD.
Set the end-face gap between the left and right fibers at the time of aligning and pre-fusion
discharge.
Set the overlape 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.
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.
Set the pre-fuse arc power from the beginning of arc discharging to the beginning of fibers
propelling. If "Preheat Arc Value" is set too low, axial offset may occur if cleaved angles are
relatively poor. If "Preheat Arc Value" is set too high, fiber end faces are fused excessively and
splice loss gets worse.
Set the pre-fuse arc time from the beginning of arc discharging to the beginning of fibers
propelling. Long [Preheat Arc Time] and high [Preheat Arc Value] lead to the same results.
Set Arc power.
Set Arc time.
