CATV PON WDM Fiber Amplifier 1550nm EDFA Support 1 2 4 Output For
FTTH Solution
Product Overview
JZEDFA series 1550nm fiber amplifier is a important optical relay
transmission equipment during 1550nm optical communication
system.In order to reach high index and dependability, main
instruments are all adopted imported famous brand to cooperate
microprocessor automatic control circuit and high dependability
switch power to assemble up. High dependability, low noise,
especially double pump design makes noise index better. Each main
technique performance index and technique plane can compare with
foreign similar machine. And with high performance to price ratio,
it is suitable for using at large or middle-size network.
Performance Characteristic
■Adopt international famous brand pump laser with the advantage of
low noise , low distortion, wide frequency band and, high output
optical power.
■Imported high-performance erbium-doped fiber, high energy
conversion efficiency.
■Support 1, 2, 3 or 4 output.
■Support two detachable backup power supplies.when the power supply
module failure, just pull out the fault power module.220 vac and 48
VDC power supply module for option.
■Adopt radiator and fan cooling together, the cooling capacity
tenfold increase.When the machine temperature more than 38 ℃, axial
flow fan automatically start, regulate internal temperature, make
the pump laser ATC control more accurate.
■Built-in microprocessor automatic monitoring circuit, real-time
accurate monitoring of all kinds of working state of the input and
output power and laser light, make sure the stability of the
optical output power, and prolong the working life of the laser
■.When the scope of work parameter deviates from the set of safety
equipment, the device automatically shut off the laser power, sound
and light alarm at the same time.
The output power is able to adjust 5dB lower by front panel button.
■Built-in LCD display on the front panel, accurate display the
working state parameters of the equipment accurately.
■With RS232 interface,RS485 industrial standard interface and RJ45
Ethernet interface (option) .It meet the needs of the various
conditions, making it easy for users to choose convenient network
management environment.
■Ethernet interface provides advanced network management function
based on the SNMP protocol.Which meet the international standards.
■Meantime with integrated network card , with functions of Web
Server, through the Ethernet interface connected to the Internet
network, complete equipment under the HTTP browsing capabilities.
