I. INTRODUCTION
The BTEA Series Erbium Doped Fiber Amplifiers are designed for 1550nm transmission
networks. They feature low noise figure, stable output power and fine environmental stability.
The EDFA is made up of two main parts:
Fiber Gain Module This is the core of the EDFA by which the EDFA can amplify the optical
signal in 1550 nm wavelength band. It is made of high quality optical components provided by
world famous companies, and carefully designed to ensure the desired specifications for its
overall performance
.
The Structure Diagram of EDFA:
Gain module of EDFA
External Control System This part is necessary to the EDFA to ensure the gain module is
working in optimum state. Controlled by micro-processor, it monitors the states of the gain
module, such as pump power, pump temperature, pump current, input and output power, and
adjusts all the parameters to ensure a stabilized output power of the gain module, and also to
maintain ideal working states. Moreover, this system provides a warning function, which can
give a warning signal 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.

III. OPERATION INSTRCTIONS
1. Connection
Connect the EDFA to the power supply when EDFA’s power switch and key lock are
both off
Be sure that the input optical power is in the right range, and the optical interfaces of
the patch cords used are in accordance with those of the EDFA.
Connect the patch cords to the input and output interfaces
2. Turn EDFA on and off
First turn on the power switch (in the back panel), the LCD will display and LED will
light. Then open the key switch, and EDFA will be in the normal working state.
To turn off the EDFA, first close the key lock, then turn off power switch after a
moment.
3. LED Indications
The six LEDs indicate as follows:
POWER, power indicator
Shows green when the power is on.
PUMP STATUS, pump states indicator
Shows green when the pump works in normal states, and shows red when the pump
is not working. The pump will be shut down in these cases: input power is less than
default setting / pump temperature is higher than 35C / pump current value exceeds
its limit value.
INPUT POWER, input power indicator
Shows green when the input power is in its right range, and red when the input power
is less than default setting.
OUTPUT POWER, output power indicator
Shows red when the output power is 3dB less than the rated output power, otherwise
shows green.
OVER TEMP, over temperature indicator
Shows green when pump temperature is below 35C, otherwise shows red. Moreover,
it will flash green when the fan is broken out and flash red when pump TEC current is
higher than 3A.
REMOTE, Remote connection
Shows green when remote control function is normal. If the indicator is not lit up there
is an internal communication problem.

IV. ERRORS AND MAINTENANCE
When the EDFA is operating normally, the front panel LEDs will all be green. If any of the
LEDs are red, it indicates an abnormal working state. In this case, please make sure that:
1. The key lock is on
2. The input power is in correct range
If the value of input power is less than default setting, the INPUTSTATUS LED will show
red. In this case the pump will turn off, and the EDFA will stop working.
3. Environmental temperature is suitable for EDFA working in its normal state
The working temperature for EDFA is from 0C to 50C. Too high environment temperature
will cause TEC current exceed its limit，thus OVERTEMP LED will show red to give a
warning. When pump temperature exceed 35C, EDFA will shut off the pump automatically,
and the PUMP STATUS LED will also show red. Besides, EDFA can not work in too cold
condition as well.
Please contact us if the problem cannot be solved by considering the above facts. Do not
repair it by yourselves.

V. SAFETY PRECAUTIONS
When the amplifier is working in normal state, the output power of light with wavelengths in
the invisible range (infrared light) may be over 16dBm (40 mW). Therefore, to avoid damaging
your eyes, please do not look into the output port of the EDFA directly.
Please do not clean the output connector when the pump laser is on in order not to damage
the connector.
The fiber amplifier is fine equipment. Therefore, please do not open the case of the amplifier
to avoid damaging the internal component devices. Opening the case of the amplifier without
the permission of us, the warranty of the EDFA will be void.

FAQ
Q: Why communication is failed between management server and SNMP agent.
A: Please try the following steps first.
1). Make sure Physical link is connected.
2). Test the connection to the administrative station through ping orders.
3). Check your IP setting (IP address, sub netmask and broadcasting address) make sure
it is correct. If SNMP administrative station is in different networks, make sure to establish
a suitable gateway IP address.
4). If SNMP can't communicate to management server and SNMP agent, please check
SNMP parameter.
5). Check read community and write community.
6). If traps are not received , check whether the address of the administrative station is
trap address, and whether IP address and community are correct.
IF the problem can not be solved through above steps, please contact us.
