Service support
The splicer provides what is referred to as "Service support". With the service support it
is possible to detect various problems including loss of alignment and contamination of
the optical components.
To use the service support, this function must be activated. It then remains active until
either the splicer is switched off or, as described below, the "splicer software" (normal
splicer function) is selected.
Activating the
service support
- The splicer must be switched on.
- Ensure that the electrode flap is closed.
- Press button
to switch into the parameter menu.
- Repeatedly press button to select the menu section "Additional functions" -
"Service data".
- Press button
to confirm the menu section.
- Press button 4 times.
The 2nd monitor page of the service data is now visible with the software section
"Service support". The two functions
• LID profile display and
• Optical test functions (with sub-functions)
are selectable for service support.

Deactivating the
service support
The service support is deactivated when the menu item "Splicer software" is confirmed
with button
. Alternatively the splicer can be switched off.
Menu "LID profile
display"
Meaning / Function
The menu item "LID profile display" is used when the timing of the splicing process
needs to be checked e.g. for determining optimum splice parameters. It can also be
used for checking the quality of the fiber ends.
Since this functions only active during the positioning and splicing process itself, the
splicer must be ready for splicing, i.e.
two correctly prepared fibers must have been
inserted in the fiber guides and all flaps must have been closed
. When the splicing
process is started after selecting the "LID profile display" menu, the optical power
transmitted across the splice point during the splicing process is measured in relation to
time and, at the end of the splicing process (or after termination of the positioning proc-
ess due to a cleave angle error), it is displayed on the monitor. The curve indicates
whether the splice parameters are correctly set and whether the cleave angle quality is
adequate.
