4. Fine polishing
Now use the pink polishing sheet for fine polishing in the same manner. Apply the connector with the
sanding gauge to the matt side of the polishing sheet with slight pressure and polish in the form of a figure of
8 up to 25 times. After the procedure the fiber end should be flat, smooth and clean.
Improving the transfer performance by fine polishing
Fine polishing with a polishing sheet can improve the transfer performance between the transmitter
and the receiver or in the cable joint by up to 0.5 dB compared with to treatment with abrasive paper
alone. For short transfer distances the polishing step can be omitted.
