WARNING: Do not look directly into the ends of fiber-optic cables or into the
transceivers on the interface faceplate. Single-mode fiber-optic cable and the
interfaces that use it (such as ATM and SONET/SDH interfaces) emit laser light
that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting
or removing cable. The safety cap keeps the port clean and prevents accidental
exposure to laser light.

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.
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.

Connecting PIC Cables
Insert the cable connector into the cable connector port on the PIC faceplate.
Arrange the cable in the cable management system to prevent it from
dislodging or developing stress points. Secure the cable so that it is not
supporting its own weight as it hangs to the floor. Place excess cable out of the
way in a neatly coiled loop in the cable management system. Placing fasteners
on the loop helps to maintain its shape.
