Safety Standards - LG-Nortel NS 161 series Manual

Safety standards

LG-Nortel products conform to all relevant safety standards. NS 161XX
(NS 16100 NN and NS 16 1G NN) complies with the following safety standards:
• IEC/EN 60950-1:2001+A11:2004—Information technology equipment - Safety,
Part 1 : General requirements
• IEC 60825-1:2001 and IEC 60825-2:2004—Safety of Laser Products
• FDA 21 CFR 1040—Performance Standards for Light-Emitting Products
Laser radiation—eye safety hazards
LG-Nortel optical products use laser or light-emitting diode (LED) sources that
emit light energy into optical fibers. This energy is within the red (visible) and
infrared (not visible) areas of the electromagnetic spectrum. FDA 21 CFR 1040
Performance Standards for Light-Emitting Products
Laser radiation hazards
When operating the product normally, with all optical connectors in position and
correctly terminated, the optical radiation is completely enclosed. The system is
a Class 1(IEC)/Class I (FDA) product, regardless of the power transmitted within
the optical fiber.
If you have unterminated optical cables (breaks in the fiber-optic cable or
disconnected connectors) the output from circuit packs containing optical
transmitters does not exceed Class 1 (IEC)/Class I (FDA) and is therefore
considered safe under all reasonably foreseeable conditions.
The following text includes additional information on the laser for the NS 161XX.
Laser wavelength 1524 - 1570 nm
Maximum laser output power <= 5 mW
Standards: IEC 60825-1:2001 Edition 1.2
Using optical fibers
All activity described herein regarding the optical interface of the NS 161XX is
intended only for trained personnel operating under the direction of the service
provider. Users and homeowners should not attempt to access or disconnect the
optical interface or damage the optical cable. Consult with the service provider
before undertaking any action involving the optical interface.
Handling optical fibers
When you work with optical fibers, you must take the following general precautions:
• Wear safety glasses when you install optical fibers.
WARNING
!
Risk of laser radiation exposure
Do not look directly into the optical beam. Invisible light can
severely damage your eyes. Keep all optical connectors capped.
• Do not look into the opening of an optical fiber, or the opening of an optical fiber
connector, if the optical fiber is active or the unit has the power turned on.
• Avoid direct exposure to optical fiber ends or optical connector ends where you
can access the laser signal directly.
• Clean your hands after you handle optical fibers. Small pieces of glass are not
always visible and can damage your eyes.
DANGER
!
Risk of eye injury
If you have a piece of a glass in your eye, get medical
assistance immediately.
• Do not handle pieces of optical fiber with your fingers. Use tweezers or adhesive
tape to lift and discard any loose optical fiber ends.
• Wear rubber gloves when you clean optical connectors. The gloves prevent direct
contact with the isopropyl alcohol and prevent contamination of the ferrules with
skin oils.
• Place all optical fiber clippings in a plastic container provided for that purpose.
• Handle optical fibers with caution. Place the optical fibers in a safe location during
installation.
• Protect all optical fiber connectors with clean dust caps at all times.
• Follow the manufacturer instructions when you use an optical test set. Incorrect
calibration or control settings can create hazardous levels of radiation.
Splicing optical fibers
When you must look at a spliced optical fiber with a small magnifier, take the
following precautions:
• Power off all laser sources to the optical fiber or disconnect the remote optical
fiber end from the laser sources before you start splicing. Make sure that all laser
sources remain disconnected or have the power turned off.
• Disconnect all optical test sets from the optical fiber before you start splicing. The
connections can be local or remote.
• Use only the optical instruments approved by your company.
