Laser Components Safety
Due to the small size of the Fiber optic module, the box packaging is labeled with the laser radiation hazard symbol and safety warning labels shown below:
User Safety
Safety and Operating Considerations
The laser light emitted from this laser diode is invisible and may be harmful to the human eye. Avoid looking directly into the fiber when the device is in operation.
CAUTION: THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT INCREASES EYE HAZARD.
Operating the laser Components outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with this component cannot exceed maximum peak optical power.
