Laser Safety

  CAUTION: Use of controls or adjustments, or performance of procedures other than those specified herein may result in hazardous laser radiation exposure.
  Invisible laser radiation may be emitted from the ends of un- terminated fiber cables or connectors. Never look directly into an un-terminated cable or connector.
  Some ONTs use a class I laser device.  

WARNING: Personnel handling fiber optic cables must be trained for laser safety.

  CAUTION: Do not bend the fiber optic cable to a diameter smaller than 7.5 cm/3 inches. Doing so may damage the fiber or prevent the signal from passing through properly.
