Foreword
This manual applies to EDFAB+PON 2U series fiber amplifier. It mainly
describes the performance characteristics, technical parameters, installation and
debugging, common troubleshooting, and other related content of the product. In
order to ensure that the equipment can be successfully installed and safely operated,
please read this manual carefully before installing and debugging the equipment. And
the installation and debugging should be strictly according to the specified steps on
the manual to avoid unnecessary damage to equipment or accident harm to the
operator. Any questions, please contact with us in time.
Special Tips:
■ Er Yb Codoped Fiber Amplifier is high end professional equipment, and its
installation and debugging must be operated by special technician. Read this
manual carefully before operating to avoid damage to equipment caused by fault
operation or accident harm to the operator.
■ While the fiber amplifier is working, there is an invisible laser beam from the
optical output adapter on the front panel. Avoiding permanent harm to the body
and eye, the optical output should not aim at the human body and human should
not look directly at the optical output with the naked eye!
■ Please make sure that the ground terminal of the case and power outlet has been
reliably grounding before turning on the power (Grounding resistance should be
＜4Ω) to prevent the static damage the pump laser device and harm to human
because of case charged.
■ To ensure the equipment can work stable over a long time, in voltage unsteady or
poor voltage wave region, it´s recommend to the customer that he equips special
AC regulated power supply, or even AC uninterrupted power supply (UPS) system
for conditional users. In the region with large temperature variation environment
(The equipment's ideal work environment temperature is 25°C) or bad room

environment, it´s recommend to the customer that he equips special air-condition
system to improve the work environment.
1. Application
 Single-mode fiber 1550 amplification network
 FTTH network
 CATV network
2. Performance Characteristics
EDFAB+PON 2U is a low noise high-performance Er Yb codoped fiber amplifier.
Each output built-in CWDM (1310/1490/1550) wavelength division multiplexer.
Conveniently multiplex the data stream of OLT and ONU to the fiber amplifier output
by 1310nm and 1490nm optical connector. Thus reduced the equipment quantity,
improved the system indexes and reliability. It is the ideal equipment for FTTx
network, provides a flexible and low cost solution for the integration of three
networks and the FTTH.
 Adopts Er Yb Codoped double-clad fiber technology;
 Output ports: 4-16 optional;
 Optical output power: total output up to 5W;
 Low noise figure: <5dB when input is 0dBm;
 Perfect network management interface, in line with standard SNMP network
management;
 Intelligent temperature control system make the power consumption lower;

1) Power indicator: One switching power supply is working – yellow; two switching
power supplies are working – green.
2) Optical input power indicator：This light turns on when the optical input power is
> -10dBm.
3) Pump working status indicator: Red light means the pump is not working, but the
machine parameters are normal; flashing red light means the machine has broken
down, related fault reason see the alarm menu of the display menu; green light
means the pump is working normal.
4) Optical output power indicator: This light turns on when the optical output power
is > +10dBm.
5) 160×32 dot-matrix LCD screen: used to display all the parameters of the
machine.
6) Display the exit or cancel key of the setup menu.
7) Display the up or increase key of the setup menu.

12) Pump laser switching key: used to control the working status of pump laser.
“ON” means the pump laser is open and “OFF” means the pump laser is closed.
Ensure the key is on “OFF” position before power on. After passing self-test,
rotate the key to “ON” position according to the displayed message.
13) Public port (COM port): This interface is the 1550nm signal output port of the
device, also is the 1310&1490nm signal in/out port. Ports number: 4-16 optional.
Warning: There is an invisible laser beam from this port while working normal.
So the port should not be aligned to the human body or the naked eye to avoid
accidental injury.

steps:
Click “start menuprogramaccessorycommunication Hyper Terminal”;
This results in the following screen:
Then you input your connection name, such as “SNMP38400”; and choose the serial
port to connect with your equipment. As follows:
Press the “OK” button shows the configuration page of serial port. As follows:
Change the serial port configuration to 38400-baud rate, 8 data bits, no parity bit, 1
stop bit, no data flow control, press the “OK” key, you have set up the Windows serial
port Hyper Terminal.

port with the computer port. Open the Windows Hyper Terminal which you have set
up. Then turn on the power, you will see the page as follows:
The application program starts normally. You can input your command in this page,
and then configure the operating parameter of the application program.
System supports the following commands:
help
ethcfg
settrap
