Juniper QFX3000-G QFabric, Deployment Manual, Page: 254 / 652

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.
