5.13 Strictly observe the following precautions when working with the Tellabs
7300 NEs:
• Avoid direct exposure to fiber ends or any other portion of the system
where the eye can be exposed to laser light.
• Protect unterminated optical fiber connectors with dust caps at all
times.
• Handle optical fibers with care during installation. Position them in a
safe and secure location.
5.14 The use of optical instruments with this product increases eye hazard.
Never view any unterminated optical fiber cable or connector with optical
instruments, as viewing optics tend to concentrate the radiation energy and thus
may increase the potential risk of injury.
DANGER:
Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
Warning:
Do not tamper with or open sealed module components.
DANGER:
Invisible laser radiation ⎯ do not stare into the beam or view it directly with
optical instruments. Looking into the end of an optical cable or connector can
cause permanent eye damage.
DANGER:
Viewing the laser output with certain optical instruments (for example, eye
loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an
eye hazard.
