Pre-Caution and Warning
Grounding
The EDFA includes Laser Diodes and Photo Diodes those are extremely sensitive to electrical static. The
operator/user must always handle the EDFA with extra care.
When the operator/user unpack or install the EDFA he
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.
Optical Connector Cleaning
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.
Sufficient Air Flow
The user must ensure there is enough air flow and convection through the upper and lower panels. The Module Type
EDFA has its own internal circuitry for Pump Laser Driving and Temperature control.
Unrestricted air flow is required for proper operating conditions.
