2.4 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:

Issue 15 (2019-12-30)
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.)
