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 polish-

ing fixture can be used to polish

two simplex connectors or simplex

latching connectors simultane-

ously, 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

connectors, 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.

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

transmitter-receiver 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/

connector face results in a tip

diameter between 2.5 mm

(0.098 in.) minimum and 3.2

mm (0.126 in.) maximum..
