Siecor 5000 Series - Making an Attenuation Splice; Setting the Default Parameters; Program Selection and Adapting the Parameters; Preparing Fibers

Operating Instructions 5-3 M90 Fusion Splicer
Issue 02/97 Attenuation Splice
Operation of the Attenuation Splice Program
The fibers are positioned in the same way as with all LID programs. Immediately before
it commences fusion, the fusion splicer automatically sets a radial offset of the fiber
axes. The fusion process consists of an initial fusion phase followed by one or more
fusion pulses and runs fully automatically until the required attenuation is reached (see
drawing).

Making an Attenuation Splice
Setting the de-
fault parameters
The default parameters stored in the fusion splicer provide the basis for all parameter
settings. You can set these parameters (for all programs jointly) by keeping button
depressed when you switch on the splicer. Please note, however, that you will then lose
the set parameters of all programs.
Program selec-
tion and adapt-
ing the parame-
ters
Use the Parameter menu to select the attenuation splice program and set the
"Attenuation" parameter to the required value. If you have set the default parameters
and are using standard fibers, you do not need to perform any further parameter set-
tings at this point. If you do not wish to set the default parameters or are using special
fiber types, refer to the Parameter Recommendations section.
Conclude parameter setting with button
.
Preparing fibers
If you use a heat-shrink splice protector, slide this over one of the two fibers. The fibers
are stripped, cleaved and inserted in the same way as with all other LID programs.
Setting the re-
quired attenua-
tion
Start the program by pressing button
. The set attenuation will be displayed. To
change the value, use buttons
and . This change then applies for the next splice
only. (You can change the default value in the Parameter menu.)
Starting the
splicing proce-
dure
Start the splicing procedure in the usual way. You can only select fully automatic /
automatic operation.
Fault message
"Bad endfaces"
If the fault message
"Bad endfaces"
is displayed during positioning, you can still con-
tinue the splicing process. In this case, however, you must expect an additional inaccu-
racy of approx. 0.1 to 0.2 dB in the attenuation displayed rsp. in the attenuation value
obtained. Press button
if you want to continue the splicing process or abort the pro-
cedure with button
.
