Personal Injury
The laser emitted by an optical module is an invisible infrared ray, which may
cause permanent eye injury. Do not look into the optical module during device
maintenance.
Equipment Damage
To prevent equipment damage when you handle the equipment, follow these
precautions:
● When not in use, the optical interfaces on the equipment and ber connectors
on
ber jumpers must be covered with dust-proof caps.
● After removing a ber jumper that connects to an optical interface on the
equipment, cover the optical interface and the ber jumper connector with
dust-proof caps.
● When performing a hardware loopback test by connecting a ber 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
Reectometer (OTDR), disconnect the
ber 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 bers.
2.4 Safety Precautions for Using Fibers
Use bers 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 ber may cause eye injury.
Do not look into optical interfaces or ber connectors during installation and
maintenance.
Cleaning Fiber Connectors and Optical Interfaces
Use special cleaning tools and materials to clean ber connectors and optical
interfaces. Common tools and materials are as follows:
● 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
