Safety Guidelines and Warnings

When removing and installing PICs that use fiber-optic cable on any routing platform, note the following guidelines.  

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.

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.

When connecting and disconnecting cable at the ports on the PIC faceplate on any routing platform, note the following guidelines. 

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.

Secure cables in the cable management system so that they do not support their own weight. Use the cable management system to place excess cable out of the way in a neatly-coiled loop. Placing fasteners on a loop helps to maintain its shape.

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.
