PERFORMANCE CHECK
6.1
Precautions for Testing
In this chapter after completing installation of the Shelf Type EDFA the proper operation,
power supply procedures, monitor connection, start test method, and other instructions are
explained. Before applying power to the Shelf Type EDFA check the Optical cable
connections on the rear panel of the EDFA once more before turning the Power Switch on.
6.2
Power Supply
Below shows the circumstances that occur when the Shelf Type EDFA is first powered up.
Check if the Power Switch on the front panel is in the OFF state.
Connect power-cords to the power sockets on the rear panel.
Turn on the Power Switch on the front panel.
All the LED’s on the front panel turn on.
The LCD on the front panel shows the Start state.
When the Start state of LCD ends, all the LED’s on the front panel turn off and, the
related LED’s turn on.
If the optical input power is normal, the EDFA stays in the “Laser ON” state.
