Inspection Precaution: Sharp bends, kinks, and deep nicks in the
cable may greatly affect cable performance. Consider replacing the
cables if they are not in good condition.
Troubleshooting Tip: To test a fiber optic cable, flash a light
through one end of the cable and see if the light comes out the other
end.
