SECTION D
Scoring
1. CAREFULLY REMOVE THE LOAD ADAPTER
2. SCORE THE FIBER
Hold the connector in a vertical position with the fiber pointing
upward. Score the fiber by drawing the scoring blade lightly
against the fiber, just above the epoxy bead (Fig. D1). The fiber
should merely be touched and not severed.
3. DETACH THE SCORED FIBER
Using your fingers, carefully remove the fiber by pulling straight up
from the ferrule. If the fiber is too short, use the scoring tool to
gently press against the fiber from the scored side until it breaks
along the score mark.
Note: Be sure to dispose of all fiber ends per company practice.
If the fiber should break off accidentally without the benefit
of proper scoring, polishing should still be attempted.
4. CHECK THE FIBER END
Check the quality of the score using the jeweler's loupe. The fiber
should not protrude from the epoxy bead more than one fiber
diameter (Fig. D2). If the fiber is longer than one diameter,
proceed as follows: Hold the connector in one hand and a sheet
of brown
5 ϑm acetate in the other. Using small circular strokes, shorten
the fiber to an acceptable length (Fig. D3).
