3.2 Front Panel Guide
3.2.1 VFD（LED）Screen
It dispels the parameters of the optical amplifier. There is several second’s delay after the power connected. When the light turn from red to green, the machine begin to work. If the light is still red and the screen shows READY:KEY OFF, this means the power connected but no optical input.
3.2.2 In
The optical input
3.2.3 Out
The Optical Output
3.2.4 Power
Turn to green after connected
3.2.5 Laser In
Green means the machine is working properly
3.2.6 Laser Out light
Green means output is properly, the light turn off if no optical out.
3.2.7 Status Light
Green light menus the amplifier is working, red means no output or trouble, at the same time the screen will display the trouble information.
3.2.8 ENT button
Press this button to see the parameters in the screen.
3.2.8.1 Model number
3.2.8.2 OUTPUT This output is the value tested after the pump laser out
3.2.8.3 BIAS
The bias current of pump laser. If the value comes out of the set value, the machine will shine.
3.2.8.4 Laser Temp（TEMP）
The laser works between 20℃ and 30℃，if the tested value comes out of this range , the machine will warm.
3.2.8.5 Cooling/Heating Current（HEATING）
This displays the working current of the pump laser(mA) when the pump laser is cooling or heating，The best working temp of the pump laser is 25℃, if higher or lower, the power laser will begin to heat or cool.

- Notes
- The main component of the amplifier laser is sensitive to the static electricity, so please keep the amplifier away from the static electricity. Furthermore, please keep it away from caustic things. Please keep the amplifier in temperature between -25℃and 65℃.
- Because big power may damage the output port, so it is advised to split to more than 4 outputs.
- Please don’t now attempt to look into the optical connectors when power applied, eye damage may result.
- Please don’t block up the heating dispersion hole and keep the machine aired.
- Please don’t unfold the machine or remove any parts of the machine.
- Please don’t insert the connectors when the power is on.
- Please don’t test the EDFA more than 5 times.
- Big power may damage the output port, so it is advised to split to more than 2 outputs.
- Input power influences C/N, so advised input value is 4dBm.

- Solution to some ordinary problem
5.1 Power supply light STATUS: green
LED light LASER: red
VFD display: NO LASER INPUT
Reason: N0 1550nm optical input
Solution: Input 1550nm optical signal
5.2 In VFD screen it displays the output value from the pigtail from pump laser, if the tested value is lower than screen.
Reason:
- The output of amplifier is out of the range of optical meter
- the input optical power is out of the requested value( -3～10dB).
- Too big loss in the test pigtail.
- There is dust in the connectors.
- The wavelength of the transmitter is big different from 1550nm will make the output value down.
Solution:
Use absolute alcohol to wash the all the connects and the test point of optical meter.
Note:
- Don’t use Chinese optical meter to test EDFA.
- Don’t test EDFA with pigtail again and again, it will hurt the fiber connector and make the factual power become smaller.
- Warranty Terms
ZJ1550nm optical amplifiers are covered by TWO YEAR Limited Warranty, which starts from the initial date of your purchase. We provide its customer whole-life technical supports. If warranty is expired, repair service only charges parts (if required). In the event that a unit must be returned for service, before returning the unit, please be advised that:
- Warranty mark pasted on the housing of unit must be in good conditions.
- A clear and readable material describes model number, serial number and troubles should be offered.
- Please pack the unit in its original container. If the original container is no longer available, please pack the unit in at least 3 inches of shock absorbing material.
NOTE: we do not assume responsibility for damage caused by improper packing of returned unit(s).
The following situation is not covered by warranty:
- The unit fails to perform because of operators’ faults.
- Warranty mark is modified, damaged and/or removed.
- Damage caused by Force Majuro.
