1. INTRODUCTION
9000EDFA-D-AGC is an Erbium Doped Fiber Amplifier (EDFA) for 1529~1561nm Dense wavelength
Division Multiplexing DWDM networks. It features low noise figures, high gain, adjustable gain, flattened
gain, stable output power and fine environmental stability. It can realize the fiber optic communication
for super span and extend relay distance. It is the ideal optical amplifier for the DWDM networks.
The DWDM EDFA consists of the amplifier module and the electrical system, see Figure 1-1.
Figure 1-1: Optical & Electrical Schematic Drawing
Amplifier Module
The amplifier module incorporates a powerful, processor-controlled gain and transient control system
for optimum performance. Input and output powers are instantly monitored to dynamically maintain the
desired operating gain under changing input conditions. This scheme enables the module to maintain
performance of the remaining channels when the numbers and the power of wavelength are added or
dropped.
External Control System
The control system is indispensable to the EDFA, to ensure the amplifier module is working in the
optimum state. Controlled by the micro-processor, it monitors the states of the amplifier module, such
as pump power, pump temperature, pump current, input and output power, and adjusts all the

parameters to ensure a stabilized output power from the gain module, and also maintains the ideal
working states. Moreover, this system provides a warning function, which can give warning signals
through the LEDs on the front panel of EDFA when the working state of the amplifier is abnormal. The
detailed working parameters of the EDFA are shown by the LCD on the front panel. This information
can also be accessed via RJ45 interface by an external computer.
Figure 1-2 portrays the front panel of 9000EDFA-D-AGC EDFA. The key switch is to control the pump
lasers; the switch button is to switch the LCD’s information.

3. OPERATION
3.1. CONNECTION
- Connect the EDFA to the power supply when EDFA power switch and key lock are both off.
- Be sure that the input optical power is in the right range (-29dBm～+7dBm), and the optical
interfaces of the linkers in use are in accordance with those of the EDFA.
- Connect the optical linkers to the input and output flanges of the EDFA.
3.2. TURN EDFA ON AND OFF
- First turn on the power switch (in the back panel), the LCD will work and LED will light. Then
open the key switch to PUMP ON, wait for half an hour and EDFA will be in the normal working
state.
- To turn off the EDFA, first close the key lock to OFF, and then turn off power switch after a few
minutes.
- Three options of the key switch:
oPUMP ON
oEYESAFE (the output power is less than 10mW)
oPUMP OFF
3.3. LED INDICATORS
The six LEDs indicate as follows:
Input power - input power indicator
- Color of the LED based on the LOS (limit of no signal). It shows red when the input power is
less than LOS.
Output power - output power indicator
- CG: the deviation of the gain from upper and lower limits exceeds 2dB, the LED shows red.
- CP: the deviation of the output power from upper and lower limits exceeds 2dB, the LED shows
red.
- CC: no alarm.
- In addition, it shows red when the input power is less than LOS or no input signal.
Remote - remote connection (optional) indicator
- Remote control shows green when the SNMP work normally.
Inside temp - inside temperature indicator
- It shows red when the inside temperature higher than 65 °C, or less than -2 °C, otherwise shows
green.
Pump bias - pump current indicator
- It shows green when the pumps work in their normal states, and shows red when the pump
current is higher than 656mA.
- The pumps will be shut down in these cases: input power is less than LOS; pump temperature is
higher than 35 °C or less than 15 °C; pump current value exceeds its limitation.
Pump temp - pump temperature indicator
- It shows green when pump temperature is below 35 °C or less than 15 °C, otherwise it shows
red.

4. ERROR AND MAINTENANCE
When EDFA is in its normal working state, the first five LEDs on the front panel will be green. If any of
the LEDs show red, it indicates an abnormal working state of EDFA. In this case, please make sure
that:
a) The key lock is on
- If the key switch is not on, the indicator of output power will show red.
b) The input power is in the correct range
- If the value of the input power is less than LOS, the input power and output power will show red.
In this case the pump will turn off, and the EDFA will stop working.
c) Be sure EDFA working temperature is in its normal state
- The working temperature for EDFA is between -2 °C to 65 °C. Any temperature over the range
will cause TEC current beyond its limit, and inside temp will show red to give a warning. If the
temperature is higher than 35 °C, the fan will run.
d) Be sure EDFA working temperature is in its normal
- When pump temperature is between 15 °C to 35 °C, EDFA will shut off the pump automatically;
the pump temp will show red.
e) The pump current is normal
- The pump bias shows red when the pump current is higher than 656mA.
f) The output power is normal
- CG: the deviation of the gain from upper and lower limits excess 2dB, the output power will
show red.
- CP: the deviation of the output power from upper and lower limits excess 2dB, the output power
will show red.
- In addition, CP/CG: if the difference of the two setting value is large (over 4dB), the output
power will show red instantly, then it will shows green. This phenomenon is normal.
g) the setting is invalid
- CP/CG/CC: if the setting value cannot be set properly several times, try the different value.
