Note: If excess epoxy is found, continue to use type J polishing paper (purple) to remove
the
excess
epoxy.
Step 3. Dome Ferrule End
a. Place the following consumables on the glass plate: one white foam pad, five clear spacers,
and on top place a sheet of type F polishing paper (yellow).
Note: Type F polishing paper can be reused by cleaning with alcohol and wipes as needed.
b. Using light pressure, polish the connector for 20 figure-8 strokes.
Note: Step 3 concludes the polishing procedure for multimode fibers. Steps 4 and 5 are to
be performed for singlemode fibers only.
Step 4. Improve Dome Surface Finish
a. Replace the sheet of type F (yellow) polishing paper with a sheet of type K (gray) dull side
up. Leave the five clear spacers and foam pad on glass plate.
b. Polish the connector for 20 additional figure-8 strokes.
Step 5. Singlemode Final Polish
a. Remove all polishing material from glass plate and replace with type L felt polishing pad
(purple).
Note: Step 5b is critical for excellent return loss. Perform carefully by guiding the polishing
tool and plug slowly and gently, never increasing pressure.
b. Dampen one-fourth of sheet with distilled water (do not flood). Buff polish 20 light figure-8
strokes, approximately 3 inches high and 1 ½ inches wide.
c. Clean fiber end with wipe dampened with water, then with a second wipe dampened with
alcohol.
d. The felt can be stored damp in a clean plastic bag and reused. The glass plate should be
immediately cleaned with water and dried completely before storage to prevent polishing
residue from permanently drying on glass plate.
Note: Step 5 provides the necessary steps for high performance return loss. Type L felt
polishing pad (purple) is imbedded with ultrafine polishing material.
