4.9 Splice procedure The status and cleaved quality of the fiber can be
monitored by using an image processing system by Swift KF4A. For better
splice result, however, visual inspection is required also.
In auto mode, the splice procedure begins automatically as the wind cover is closed.
i. Fibers installed on the splicer advance toward each other and stop. The
fibers align once cleaning arc is done. After that, the splicer checks cutting
the cleaved angle of each fiber, the shape of the end faces, contaminations
and so on. When the measured cleaved angle is bigger than the preset value
or damage is detected on fiber, error message is displayed on the screen.
And splice procedure stops as well. Even if there is no error message
displayed, visual inspection on the monitor screen is always recommended.
ii. Fibers are aligned cladding to cladding after inspection. Deviation on clad
axis can be displayed on screen.
iii. After alignment completes, arcing is conducted to splice fibers.
iv. After splicing is completed, the estimated value of loss is displayed on the
screen. The estimated value of splice loss is subject to various factors
related to error. These factors related to an error affect the estimation and
calculation of estimated loss value as well. Calculation of estimated loss is
based on factors such as MFD. When estimated loss value exceeds the
preset value and error message is displayed on the screen. The error
message is also displayed when the spliced fibers are too thick or thin or
when bubbles are generated on the spliced point. If the splice result shown
on the screen is not considered good enough, it is recommended to conduct
splicing again
v. The splice result is saved as follows.
When splice completes, splice result is automatically saved.
