Basic Operation
Splicing procedure
To make a good splice, the optical fiber is observed with the image processing system
equipped in the 70S. However, there are some cases when the image processing system
cannot detect a faulty splice. Visual inspection with the monitor is often necessary for better
splicing yield. The instruction below describes standard operating procedure.
1.
Fibers loaded in the splicer move
forward toward each other. The fiber
forwarding motion stops at a certain
position shortly after the cleaning arc
is performed.
2.
Next, the cleave angle and end-face
quality are checked. If the measured
cleave angle is greater than its set
threshold or fiber chipping is
detected, the buzzer will sound and
an error message warns the operator.
3.
If no error message is displayed, the below stated end-face conditions are used for
visual inspection. If observed, remove the fiber from the splicer and repeat fiber
preparation. These visual defects may cause a faulty splice.

Pause after cleave angle check and fiber alignment can be set “disabled”. See
section [Splice Settings] for detail.
The cleave angle threshold can be changed. See section [Splice Menu]
The cleave angle error message can be ignored by pressing SET key to go on to the
next step. To disable the cleave angle error. See section [Splice Settings] for detail.
Cleave angle, during the splicing operation can be hidden. See section [Splice
Settings] for detail.
