The fiber optic interface product used in Option 11C is considered
safe. However, as a precaution do not view the optical port or the end
of fiber optic cable. Under certain conditions (such as during cable
testing or under light magnification) the cable or port may expose the
eye beyond the limits of Maximum Permissible Exposure
recommended in some jurisdictions. Do not remove protective caps or
plugs until ready to connect the cable.
