it is also strongly prohibited from iterating of power on/off in very shot interval. The
recommended on/off interval is at least 5secconds.
The optical adapters for the EDFA input and output are located on the front panel of the
Shelf Type EDFA. When received from the factory the optical adapters have a cap on
them for safety and protection. Until the Shelf is installed you need to leave the caps on.
The operator/user must keep the surface of the optical connecter clean. If the surface of
the optical connecter is contaminated with dirt or obstructions the surface of the optical
connecter may be damaged as soon as the Laser is turned on.

Grounding Considerations
The Shelf Type EDFA includes Laser Diodes and Photo Diodes those are extremely
sensitive to electrical static. You must always handle the EDFA with extra care. When
you unpack or install the EDFA you must obey all the ESD (electro static discharge)
precautions as well as work with a grounded wrist strap. Therefore, proper ESD
precautions are always recommended. To avoid performance degradation or loss of
functionality, install in a properly grounded working shelf. The F.G. terminal must be
connected to Earth Ground for protection of the unit during installation and operation.
To protect the installation and to prevent unexpected accidents, such as lightning, static
electricity, short circuit, surges, etc..., you must use a grounded receptacle for the AC
power cord.
