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.
1.6

LED State Information
„ POWER LED
When an electric power is applied to the EDFA and the power switch is turned on, the
POWER LED in the power switch turns on.
„ ACT LED
When the EDFA is properly installed, the ACT LED turns on.
However, if the Provision Menu is selected the DEACT state, the ACT LED turns off.
„ LOS (Loss of Signal) LED
When the input optical signal power to the EDFA is lower than the minimum input
conditions, the LOS LED turns on (see the TEST REPORT). The threshold for
triggering the loss of input signal alarm is set below the minimum optical input level.
Commonly 3dB below the minimum input power level is set as the threshold.
If the LOS alarm is activated the EDFA automatically changes to the Laser Shutdown
state, the output power is turned off, and the LOP LED turns on.
In response to a loss of input signal, the bias current of the pump laser diode goes into a
shutdown state to prevent the development of dangerous laser diode operation conditions.
If laser shutdown does not occur, the pump laser diode can be damaged.
This condition is automatically reset when the input power is restored to a power above
the alarm threshold for the EDFA. The EDFA returns to its normal state, the LOS LED
turns off, and the Laser ON state condition returns. If the output power of the EDFA is
normal, the LOP LED turns off.
„ LOP(Loss of Output Power) LED
When the optical output power of the EDFA is lower than the reference power, the LOP
LED turns on. (see the TEST REPORT) This level is commonly 3dB below the
reference output power.
If the Laser OFF state is selected from the LCD menu, the LOP LED turns on.
The LOP alarm turns off when the output optical power of the EDFA is normal.
„ BIAS LED
The Pump Laser Diode provides pumping energy to the Erbium Doped Fiber in the EDFA.
The pumping power of the Pump Laser Diode is controlled by applying a bias current. If
the bias current of the pump laser diode is loaded above 95% of the end-of-life (EOL)
value, the pump bias current alarm is activated. The EOL bias current is defined as 120%
of the beginning-of-life (BOL) bias current. The pump laser diode driver is limited to
never exceed the EOL bias level. This is an indicating LED for an over current
condition of the Pump Laser Diode bias current.

User’s Manual
November 2007
If the BIAS alarm is activated the EDFA changes automatically to the Laser Shutdown
state, the EDFA output power is turned off, and the LOP LED turns on.
„ TEMP LED
The internal temperature of the Pump Laser Diode must be kept constant. If the internal
temperature of the Pump Laser Diode goes outside of the operational range, the TEMP
LED is activated.
If the TEMP alarm signal is activated the EDFA automatically changes to the Laser
Shutdown state and the LOP LED is activated.

In SNMP, SNMP Manager (console) first request data and then SNMP Agent (Shelf-OFA)
response with requested data. When an alarm occurs, SNMP Trap containing the alarm
information, created by SNMP Agent, is sent to SNMP Manager without request from the
recipient. SNMP Manager should be prepared with SNMP Trap Receiver for this feature.

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.

6.3
Check if the Power Switch on the front panel is in the OFF state.
Connect power to the related power sockets on the rear panel.
Turn on the Power Switch on the front panel.
The green LED of the Power Switch turns on.
All the LEDs 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 LEDs on the front panel turn off and the
Alarm Signals are activated normally. If the EDFA is installed, the related ACT
LED turns on.
If the optical input power is normal, the EDFA stays in the “Laser ON” state.

Test procedure of the Shelf Type EDFA
1) Connect the measuring instrument in Figure 4.
2) Check the optical signal power from the optical source ⓐ by using the optical power
meter. The optical signal power from the optical source must be above the minimum
optical input power of EDFA. The minimum optical input power and operating
wavelength referred to the TEST REPORT.
3) Next make sure to check the input power range of the optical power meter. The
EDFA optical output power is very high, the optical power meter may be heavily
damaged if not properly adjusted.
4) Connect the output adapter of the EDFA to the optical power meter through the optical
jumper cord.
5) If the optical power meter is unable to measure the optical output power of the EDFA
directly you must use the optical attenuator.
6) Under normal operating conditions, that is, LASER ON state, and the optical input
power condition is within the optical input power range of the EDFA, check the optical
output power of the EDFA (ⓑ).
6.4
Alarm Test
The LOS Alarm of the Shelf Type EDFA occurs when the optical input power of the
EDFA is lower than the minimum optical input power condition (see the TEST REPORT).
If you want to check the LOS Alarm, tune the input power of the EDFA by using the
optical variable attenuator to a value below optical input signal minimum.
When the LOS Alarm is activated the related LOS LED on the front panel turns on.
At this time the Shelf Type EDFA automatically changes to the Laser Shutdown state and
the LOS Alarm is also activated.
The state information value of the Shelf Type EDFA stores both the occurred events and
the time they happened.
If the Buzzer selection in the LCD menu is in the ON state, the Buzzer sound goes beep.
The Buzzer sound can be eliminated by pushing the any switch on the front panel or by
selecting the correct condition within the Buzzer ON/OFF menu of the LCD menus.
If the Buzzer selection in the LCD menu is in the OFF state the Buzzer sound does not
sound and just the state information and time values are stored. When the optical input

power of the Shelf Type EDFA is normal, the LED on the front panel and the Buzzer
sound automatically turn off. In this case the state information also is automatically
stored.
