Splice procedure
The status and cleaved quality of the fiber can be monitored by using a FX Fusion Splicer
image processing system. For better splice results, however, visual inspection is also
required.
In auto mode, the splicing 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 arc cleaning is done. After that, the splicer checks the cleaved angle
of each fiber, the shape of the end-face contaminations and so on. When the
measured cleaved angle is bigger than the preset value, or damage is detected
on the fiber, an error message is displayed on the screen. The splice procedure
stops as well. Even if there is no error message displayed, visual inspection of
the monitor screen is always recommended.
ii.
Fibers are aligned, cladding to cladding, after inspection. Deviation on clad
axis can be displayed on the screen.
iii.
After alignment completes, arcing is conducted to splice fibers.
iv.
After splicing is completed, the estimated value of the loss is displayed on the
screen. The estimated value of splice loss is subject to various factors related
to the 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, an 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 that splicing be conducted again.
v.
The splice result is saved as follows.
When splice is completed, the splice result is automatically saved.
