When inserting the wires into the connector ensure the optical channels are crossed (Tx1 → Rx2; Tx2 →
Rx1). The 'nose' at the connector hinge can be used as a guide.

3. Grinding and polishing
Any fibers protruding more than 1.5 mm from the connector should be shortened with a cutter knife or a pair
of scissors.
Now push the connector fully into the sanding gauge, so that the ends to be polished protrude from the lower
side. The sanding gauge is suitable for polishing one or two simplex connectors or a duplex connector.
