LASER SAFETY:Class 3R Laser ProductThis is a Class 3R Laser Product as defined by International Standard IEC 60825-1, Edition 2. Invisible Laser radiation is emitted from the end of
the fiber or connector. Avoid direct eye exposure to the beam. Laser safety labels are not attached to the module due to space limitations but
instead are affixed to the outside of the shipping carton.
