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.
