1.4 Safety Precautions for Using Fibers

Use fibers in a safe and correct manner to ensure proper operation of the equipment and
prevent personal injury and equipment damage.
The laser beam on an optical interface board or from a fiber may cause eye injury. Do not
look into optical interfaces or fiber connectors during installation and maintenance.
Cleaning Fiber Connectors and Optical Interfaces
Use special cleaning tools and materials to clean fiber connectors and optical interfaces.
Common tools and materials are as follows:

When not in use, the optical interfaces on the equipment and fiber connectors on fiber
jumpers must be covered with dust-proof caps.
After removing a fiber jumper that connects to an optical interface on the equipment,
cover the optical interface and the fiber jumper connector with dust-proof caps.
When performing a hardware loopback test by connecting a fiber jumper to an optical
interface, add an attenuator to prevent the risk of damage to the optical module caused by
excessively strong optical power.
When using the Optical Time Domain Reflectometer (OTDR), disconnect the fiber
jumper between the peer equipment and the local equipment to avoid damage to the
optical module caused by excessively strong optical power.
Unless necessary, do not remove or insert the modules connecting to fibers.
Special cleaning solvent (Isoamylol is preferred, propyl alcohol is the next option,
however ethanol and formalin are forbidden.)
Non-woven lens tissue
Dedicated compressed gas
Cotton stick (medical cotton or long fiber cotton)
Special cleaning roll (used with preceding special cleaning solvent)
Magnifier for optical connectors
