Step 4
Place the flush connector and polishing fixture on the dull
side of the 3 µm pink lapping film and continue to polish
the fiber and connector for approximately 25 strokes. The
fiber end should be flat, smooth and clean.
This cable is now ready for use.
Note: Use of the pink lapping film fine polishing step results in
approximately 2 dB improvement in coupling performance
of either a transmitterreceiver link or a bulkhead/splice over
a 600 grit polish alone. This fine polish is comparable to the
Avago factory polish. The fine polishing step may be omitted
where an extra 2 dB of optical power is not essential, as with
short link lengths. Proper polishing of the tip of the fiber/con
nector face results in a tip diameter between 2.5 mm (0.098
in.) minimum and 3.2 mm (0.126 in.) maximum..
Step 3
Any excess fiber protruding from the connector end may
be cut off; however, the trimmed fiber should extend at
least 1.5 mm (0.06 in) from the connector end.
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 or simplex latching connectors
simultaneously, or one duplex connector.
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. Typically, the polishing fixture can
be used 10 times; 10 duplex connectors or 20 simplex con
nectors, two at a time.
Place the 600 grit abrasive paper on a flat smooth surface,
pressing down on the connector, polish the fiber and the
connector using a figure eight pattern of strokes until the
connector is flush with the bottom of the polishing fixture.
Wipe the connector and fixture with a clean cloth or tissue.
