Foreword
This manual applies to WE-1550-YZBCW 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

-
- 3 3 - -
＜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
 CATVnetwork
2. PerformanceCharacteristics
WE-1550-YZBCW 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: 4-64optional;
 Optical output power: total output up to 8W;
 Low noise figure: <6dB when input is 0dBm;
 Perfect network management interface, in line with standard SNMP
network management;
 Intelligent temperature control system make the power consumption lower;

“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: 4-64 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.
