3.7. Splicing operation
It uses image processing to identify abnormal conditions that sometimes occur during the splicing process. A
small portion of these defects sometimes goes undetected and a poor quality splice occurs. Visually inspect the
fiber image on the monitor to confirm acceptance or rejection during the various stages of the splicing process.
Start of splicing
Press to move the left and right fibers forward. After completion of cleaning the arc discharge, the fibers
stop at the predetermined position.

Note: When the fiber are moving forward and they appear to hop up and down, contamination may be
present in the V-grooves or the fiber surface, Clean the V-grooves and redo fiber preparation.
Cleave angle measurement and alignment operation
Visually examine the condition of the fiber end-face while the splicer is in operation or at a pause.

Check: Even if no cleave angle error is displayed, press and redo fiber preparation if the following
cases occur.
Fig.3-7 Fiber End Face
When the threshold of cleave angle is exceeded, an error message is displayed: “Left Fiber End-face badness” or
“Right Fiber End-face badness”. Redo cleave fiber.
