1. Safety instructions
Before installing and using products, please read the following carefully. The
company shall not be responsible for any loss caused by any breach of safety.
The output of the laser and erbium-doped fiber amplifier is high-power invisible
radiation. When the device works, it must not look directly at its connecting ends, so
as to avoid burns to the eyes and skin.
The device contains precision optical devices to avoid damage caused by severe
impact. Avoid severe vibration and collision. The tail fiber is easily damaged. Please
operate carefully.
The device contains electrostatic sensitive devices. Please be careful to operate
and ensure good grounding and normal power supply.
It is best to use AC voltage stabilizer to supply power in areas with unstable grid
voltage or poor voltage waveforms.
Special attention to optical fiber connector:
before using device, please make sure that the connector of the input and output
tail fiber is kept clean, especially if the output fiber connector has dirty goods, it
is easy to burn out output tail fiber and make the output optical power become
smaller. When cleaning the optical fiber end or inserting optical jumper, please
shut down the input light first. If you use alcohol to clean the fiber end, only it is
completely dry, you can connect fiber to use.
the correct order of plugging and unplugging is: for plugging optical fiber, first
inserting the output optical fiber and then inserting the input optical fiber. For
unplugging optical fiber, first pulling out input optical fiber, and then pulling
out the output optical fiber..
this EDFA is a high precision and high stability product. In order to make the
output power have high stability, please use excellent quality optical fiber . In
principle, the optical fiber should be as short as possible, and do not allow the
optical fiber to move random.
When the EDFA is not used, if there is no active cable connector connected to the

input and output optical port of EDFA, please cover dust-proof cap to prevent the
input and output end from being contaminated.

3. Operation instructions
To ensure the normal operation of EDFA, you must operate in accordance with
the following methods:
3.1 Connection
Ensure that the device is well grounded;
Measure input optical power, confirm within the EDFA input optical power
range, check the input and output optical fiber connector whether is
consistent with EDFA optical interface connector, and cleaning the connector
ends;
Connect input and output optical fiber.
3.2 Turn on/off procedure
when key switch is closed, plugging the power line of rear panel, turning on
power switch, at this time, the LCD screen is on and LED indicator displays
green. After a moment, turn on key switch, Preheating 5-10 minutes, and
EDFA enters the normal working state.
The sequence of shutting down is opposite to the starting order. Firstly , turn
off key switch, secondly, turn off power ,and unplug power line.
3.3 LED indicator description
The front panel LED indicator shows the following contents:
Power Indicator
When connecting power, green LED is on.
Alarm state display
When normal working, alarm led should turn off. After turn off pump laser,
alarm led flash red(including key switch shutting down and all kinds of
alarm state. Example for: input optical power below -5dBm)
Alarm indicator

Various alarm status LED flash red lights.
Remote monitor and control
When the external computer and EDFA are connected, you can view the
working parameters of the device through the Web page. First, input the
192.168.1.100 (default IP address) in the browser's address bar, second, click
the “enter”, and enter the login page to input the default username "admin",
and the password "admin".
3.4 Button description
NEXT
Pressing this button can view EDFA all kinds parameters from top to bottom.
When modified parameters, this button is downward value.
ENTER
Enter next level sub-menu, when finishing modifying, please press this
button to confirm change.
3.5 Display menu description
