Laser Safety for Fiber Optic Back
Modules
WARNING!
Use of controls, adjustments, and procedures other than those specified in this document may result
in hazardous laser radiation exposure.
Optical fiber telecommunication systems use semiconductor laser transmitters that emit infrared light
that is normally not visible to the human eye. Although a conventional laser produces a small beam of
light, the power density is very high, and it can damage your eyes.
If a beam of laser light enters the eye, the eye magnifies and focuses the energy on the retina. The
energy that reaches the retina can be as much as 100,000 times more than at the cornea and, as a
result, it can burn the retina.
Laser transmission products are classified in four major groups (Class 1, 2, 3, and 4), according to their
emissions and potential for causing injury. Fiber optic transmitter modules in this series are designated
Class 1.
Precautions for Enclosed Systems
In its normal operating mode, an optical fiber communication system is totally enclosed and presents no
risk of eye injury. However, if the fiber optic cables that interconnect various components of an optical
fiber disconnect or break, you may be exposed to laser emissions. Also, technicians may be exposed to
laser emissions during installation and servicing.
