Product and personnel safety guidelines

This section contains safety guidelines that you must follow for personal safety and
to operate the equipment correctly.
LG-Ericsson documentation contains precautionary messages and safety procedures
that refer to specific tasks or conditions. You must read and follow all precautionary
messages before you start to work on the equipment.

Audience

Personnel working directly on equipment must be

• trained, authorized, and qualified to carry out the tasks required

• able to follow safety guidelines specific to the product and all local customer-specific
safety procedures

Precautionary messages

To prevent personal injury, equipment damage, and service interruptions, you must
follow all precautionary messages in LG-Ericsson documentation and all local safety
standards required by your service provider.
The following precautionary messages appear in LG-Ericsson documentation:

Safety standards

LG-Ericsson products conform to all relevant safety standards. The EARU 1112 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-Ericsson 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 EARU 1112 .

Laser wavelength 1530 - 1600 nm

Maximum laser output power <= 0.299 mW (-5.25 dBm)

Standards: IEC 60825-1:2001 Edition 1.2

FDA 21 CFR 1040.10:2000

Using optical fibers

All activity described herein regarding the optical interface of the EARU 1112 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.

• 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.

• 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.

Repairing optical fibers

When an accidental break occurs in the optical fiber, do the following:

• Report the location of the damaged optical fiber to both the service provider and
the field repair personnel.

• Power down all laser sources to the optical fiber or disconnect the remote optical
fiber end from the laser sources.
