Laser Safety

This equipment contains an infrared laser that transmits intensity-modulated light and emits invisible radiation.

Warning: Radiation


Warning

  • Avoid personal injury! Use of controls, adjustments, or procedures other than those specified herein may result in hazardous radiation exposure.

  • Avoid personal injury! The laser light source on this equipment (if a transmitter) or the fiber cables connected to this equipment emit invisible laser radiation. Avoid direct exposure to the laser light source.

  • Avoid personal injury! Viewing the laser output (if a transmitter) or fiber cable with optical instruments (such as eye loupes, magnifiers, or microscopes) may pose an eye hazard.


  • Do not apply power to this equipment if the fiber is unmated or unterminated.

  • Do not stare into an unmated fiber or at any mirror-like surface that could reflect light emitted from an unterminated fiber.

  • Do not view an activated fiber with optical instruments (e.g., eye loupes, magnifiers, microscopes).

  • Use safety-approved optical fiber cable to maintain compliance with applicable laser safety requirements.

Warning: Fiber Optic Cables


Warning

Avoid personal injury! Qualified service personnel may only perform the procedures in this manual. Wear safety glasses and use extreme caution when handling fiber optic cables, particularly during splicing or terminating operations. The thin glass fiber core at the center of the cable is fragile when exposed by the removal of cladding and buffer material. It easily fragments into glass splinters. Using tweezers, place splinters immediately in a sealed waste container and dispose of them safely in accordance with local regulations.



Warning

Eye injury can occur - do not pull optical connector or look into the connector or the fiber cable while the node is energized.
