Product installation should only be performed by trained service personnel.
Do not bend the fiber optic cable to a diameter smaller than 7.5cm/3 inches. Doing so
may damage the fiber or prevent the signal from passing through properly.
Laser Safety
D !
Personnel handling fiber optic cables must be trained for laser safety.
ANGER
D !
Optical Fibers emit invisible laser radiation. Avoid direct exposure to the
ANGER
beam. Never look into the end of a Fiber or into a Fiber connector on a cable or a
device. Permanent eye damage or blindness can occur quickly from laser radiation.
Electrical Safety
D !
Do not open the enclosure unless directed to do so by Tellabs technical
ANGER
support. Doing so is dangerous and voids the warranty.
• Check that the DC power supply polarity is correct. The ONT will not be damaged
by reversed polarity but will not operate until the polarity is corrected.
• Do not install electrical equipment in wet or damp conditions.
• Ensure that the power source for the system is adequately rated to assure safe
operation and provides current overload protection.
• Do not allow anything to rest on the power cable, and do not place this product
where people can stand or walk on the power cable.
