Juniper EX4650 Series User Manual

CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening point.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause problems that
are difficult to diagnose.
