Basic Operation
9. Splicing procedure
To assure a good splice, the optical fiber is observed with the image processing system
equipped in the FSM-50S. 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. Procedure 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. 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.
The splicing procedure pauses.
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.
(2) After fiber inspection, the fibers are aligned core-to-core or cladding-to-cladding.
Cladding axis offset and core axis offset measurements can be displayed.
• Pause after cleave angle check and fiber alignment can be set to disabled.
See [Splice Option] (Page 46) for details.
• The cleave angle threshold can be changed. See [Splice Option] (Page 46)
for details.
• The cleave angle error message can be ignored by pressing
SET
to go on to
the next step. To disable the cleave angle error, see [Splice Option] (Page 46)
for details.
• Cleave angle, cladding axis offset and core axis offset during the splicing
operation can be hidden. See [Splice Option] (Page 46) for details.
