Cut the fiber
Cut and remove outer jacket (at least 10-15 cm)
Cut and remove aramid/kevlar yarn
For each fiberoptic line:
put on heatshrink tubing on one end
remove (colored) buffer - smallest hole on the stripper tool, take off in ~1cm chunks - ensure waxy material between cladding and buffer layer is removed as well
cleanup using kimwipes and IPA - fiber should be squeaky clean :3
put fiber in the cleaver - buffer should end up on 10mm mark
close the cover, push the button, get rid of cut fiber piece…
align cleaved fiber in the slicer - tip of the fiber should be aligned with inner edge of a blue plastic guide - remember to fully close the fiber clip
Do the above for other fiber line to splice
Press green button
Pray
After successful splice open the cover, wait for pull test, after a couple of seconds unclip both ends of the fiber
Pull on heatshrink over the exposed fiber part
Open the heater in upper half of the splicer, close it down
Wait for heater to shrink the tubing
After it finishes, take it out, ensure the heatshrink is properly sealed - otherwise repeat the heating cycle…
