Grinding and Polishing BFOC Connectors
To grind the BFOC connector, insert it in
the black polishing disc. Grind down the excess fiber by
describing a figure-of-eight on polishing
paper (400 grit) on a flat solid surface by
applying gentle pressure to the
connector. Remove the connector from the polishing
disc and remove the debris with a soft
lint-free cloth.
Fit the connector into the white polishing
disc Finally, place the light gray polishing
paper (1500 grit) on a firm flat surface
and polish the connector end face by
describing a figure of eight while applying
gentle pressure to the connector.
Repeat the figure-of-eight movement
approximately 25 times. Remove the connector from the polishing
disc and remove the debris with a soft
lint-free cloth.
Repeat this procedure with the second
connector.
