look into the end of an optical fiber cable or open receptacle. Although shining light into
one end and looking into the other end of a disconnected optical fiber to verify the
continuity of optic fibers many not injure the eye, this procedure is potentially
dangerous. Therefore, verifying the continuity of optical fibers by shining light into one
end and looking at the other end is not recommended. To verify continuity of a fiber
optic cable, use an optical light source and power meter. (C027)
