4.8 Optical fiber connecting procedure
State of optical fiber can be observed by using image processing system installed on Swift K11. For
better splice result, however, visual inspection is additionally required.
Upon auto mode, splice procedure automatically starts when windbreak cover is closed.
i.
Optical fibers installed on sealer advance toward each other. Advancing optical fibers
move to a location where splice can be done after cleaning discharge. After that, the
sealer checks cutting angle of optical fiber, the state of tip’s cross section, dust, etc.
When the measured cutting angle is bigger than the preset limitation or when damage
is detected on optical fiber, error message is displayed on the screen. And splice
procedure stops as well. Even when there is no error message displayed, however,
visual inspection on the monitor screen is always recommended.
ii.
Optical fibers are arrayed core vs core after inspection. Deviation on clad axis and
deviation measured on core axis can be displayed on screen.
iii.
After alignment completes, arcing is conducted to splice fibers.
iv.
After splice completes, estimated loss value is displayed on screen. Estimated value of
splice loss is subject to various factors related to error. These factors related to error
affect 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 limitation, error message is displayed on the screen. The error message is also
displayed when the spliced optical fiber is too thick or thin or when bubbles are
generated on the joint. Even when there is no error message displayed, however, it is
recommended to conduct sealing yet again when the splice result on screen is
considered not good enough.
v.
Splice result is saved as follows.
When splice completes, splice result is automatically saved.
