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
shortlinklengths. Properpolishingofthetipofthefiber/con
nector face results in a tip diameter between 2.5 mm (0.098

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.
