6.2.3 Stuff Measure
This function measures the stuffing amount of left hand side fiber. The left
fiber automatically stuffs towards the right fiber during discharge. The stuff
amount is very important for splice quality.
1. Selection of "STUFF MEASURE"
Display "Maintenance Mode" menu and move "
∗
" symbol next to the
"STUFF MEASURE"
2. Execution of the "STUFF MEASURE"
Set both left and right fibers onto the V-grooves before starting this
function. The fiber ends must be cleaved precisely.
Then press the "SET" key. The splicer checks stuff amount automatically.
3. Stuff Check Process
The splicer automatically proceeds with the following steps.
(1) Gap setting and Cleaning Arc
Both fibers move forward and a cleaning Arc occurs. Then both fibers
stop when distance between the fiber ends be proper.
(2) Stuffing and measurement
The right fiber moves backward, and the left fiber stuffs forward. Then
the splicer measures and displays the stuff amount of the left fiber.
(3) Calculate average
In order to eliminate the effect of any variability of the stuff amount,
perform this function at least 5 times, and calculate average of the
results. Acceptable stuff amount is from 26um to 32um.
(4) Adjustment of Stuff Amount
If stuff amount is not acceptable, please increase or decrease
“FORWARD” time. Concerning adjustment of the "FORWARD"
parameter, refer to Section 5.1.1.
(5) Quit from the Stuff Check Function
Press the "RESET" key.
6.2.4 ELECTRODE
This function is used to adjust the gap set position. This function is only for
trained personnel.
6.2.5 CENTER SHIFT
This function is used to adjust the relationship of X field gap set position and
Y field gap set position. This function is only for trained personnel.
