3. Insert the cable connector into the optical transceiver (see

4. Secure the cables so that they do not support their own weight. Place excess cable out of the way in
a neatly coiled loop. Placing fasteners on a loop helps cables maintain their shape.
CAUTION: Do not bend fiber-optic cables beyond their minimum bend radius. An arc
smaller than a few inches in diameter can damage the cables and cause problems that
are difficult to diagnose.
Do not let fiber-optic cables hang free from the connector. Do not allow fastened
loops of cables to dangle, which stresses the cables at the fastening point.
