1.0 PRODUCT SUMMARY
1.1 Product summarize
EDFA is the great achievement of opto-electronics in the international
information field in recent decade. Its appearance leads to the revolution of
optic-communication, brings revolutionary progress for CATV transmission
with high quality, long distance and large area, and also reduces the
building cost of the network greatly.
GA5100 amplifier adopts the mature 1550nm module technology of
international famous company. The core components are all originally
imported from America, which provides high quality and high reliability for
the products.

2.1.3 Menu assistant manual
1. Input power (INPUT):
Input power >+10 dBm, display HIGHER;
Input power <-10 dBm, display LOWER.
2. Output (OUTPUT):
When input display HIGHER or LOWER, the output power displays
NO OUTPUT.
3. Laser temperature (TEMP): °C. The laser temp is seted in the
range of 20°C~30°C. If the detected temp exceeds the range, the

red light will show an alarm and the power supply of the laser will
be off automatically.
4. Bias (BIAS): Bias is the key index of the laser. If the fixed range is
exceeded, the power supply of the laser will be off automatically
to protect the laser
5. +5Vvoltage(+5V READS) >±0.5V alarm.
-5Vvoltage(-5V READS) >±0.5V alarm.
6. Press ▲\▼ key to amend the IP address menu that needs to be
amended. Press ▲▼ at the same time to enter the menu, press
▼ to choose the amended place, push ▲ to amend, and then
press ▲▼ to enter into save and exit.
For example, amend IP setup menu, IP: 192.168.000.015; if you
want to change 5 to 6, use ▲▼ to enter the IP menu, then press
▼ to choose the place of 5, press ▲ key to change 5 to 6, and
then press ▲▼ to save amended IP:192.168.000.016

4.0 DESCRIPTION OF STATUS ALARM
Working status indication (LED) is near the powers supply switch in the front panel.
When it is green, the device is working properly; when it is red, the laser does not
work; when it is red sparking, there is an alarm.
A. With 220V power supply, if the machine is good, the digital panel will display
“READY: KEY OFF” and there is Red light.
B. Turn on with the key, the digital panel will display “KEY OFF”. After a few
seconds, the laser is turned on automatically and the indication light turns
into Green from Red.
C. Pressing ▲\
▼ bottom can display parameters .
D. If any fault listed above occurred, there will be an alarm (Red sharking),
Microprocessor will cut down the laser automatically, and digital panel will
show the reason of the fault.
E. In order to protect the laser, the power supply of the laser has time-delay
function. After turning on with the key, the laser will start to work after 10
seconds.
5.0 OPERATION NOTICE
1. The machine should have good grounding with grounding resistance<4
Ω.
2. The machine adopts high performance, high reliability, and steady voltage
switch power supply. It has constant voltage overflow protection and can work
in 220 VAC electric network. The micro-processor can monitor the output DC
voltage. If the Fuse is melted broken, it will show that the machine’s inner
parts has occurred problems.
3. In order to make sure reflect loss is ≥45dB, we use SC/APC connector; other
type (such as FC/PC) cannot match with it. Keep the connector clean when

installing. After several plug-in/out, clean it with degreased cotton with
anhydrous alcohol.
4. Do not turn on the machine separately or without protection cover at the
connector end. Otherwise the laser will do harm to human body, especially
eyes.
