Step 3: Trimming and Polishing
Any fiber in excess of 1.5 mm (0.06 in) protruding from
the connector end should be cut off with wire cutters or
scissors.
Insert the connector fully into the polishing fixture
with the trimmed fiber protruding from the bottom of
the fixture. This plastic polishing fixture can be used to
polish two simplex connectors simultaneously or one
duplex connector.
Step 4: Finishing
Place the flush connector and polishing fixture on the
dull side of the 3 µm pink lapping film and continue
to polish the fiber in the same figure eight pattern for
approximately 25 strokes. The fiber end should be flat,
smooth and clean.
Note: The four dots on the bottom of the polishing fixture
are wear indicators. Replace the polishing fixture when
any dot is no longer visible.
Press the polishing tool down on the 600 grit abrasive
paper. Polish the fiber using a figure eight pattern until
the connector is flush with the bottom of the polish-
ing fixture. Wipe the connector and fixture with a clean
cloth or tissue.

Note: Use of the pink lapping film fine polishing step
results in approximately 2 dB improvement in coupling
performance of either a transmitter-receiver link or a bulk-
head/splice over a 600 grit polish alone. This fine polish is
comparable to the Avago Technologies factory polish. The
fine polishing step may be omitted for short link lengths.
